Learn About the Tarantulas Family Theraphosidae

Tarantulas look big and scary, but theyre actually rather docile and virtually harmless to people. Members of the family Theraphosidae exhibit some interesting behaviors and share certain traits. Description Chances are, you would recognize a tarantula if you came across one, without knowing much at all about the traits that define it as a member of the family Theraphosidae. People recognize tarantulas by their enormous size, relative to other spiders, and by their conspicuously hairy bodies and legs. But theres more to a tarantula than hair and heft. Tarantulas are mygalomorphs, along with their close cousins the trapdoor spiders, the purse-web spiders, and the folding-door spiders. Mygalomorphic ​spiders have two pairs of book lungs, and large chelicerae bearing parallel fangs that move up and down (rather than sideways, as they do in araneomorphic spiders). Tarantulas also have two claws on each foot. See this diagram of the parts of a tarantula for more information about the tarantula body. Most tarantulas live in burrows, with some species modifying existing crevices or burrows to their liking, and others constructing their homes from scratch. Some arboreal species climb off the ground, living in trees or even on cliffsides. Classification Kingdom – AnimaliaPhylum – ArthropodaClass – ArachnidaOrder – AraneaeInfraorder - MygalomorphaeFamily - Theraphosidae Diet Tarantulas are generalist predators. Most hunt passively, by simply lying in wait near their burrows until something wanders within reach. Tarantulas will eat anything small enough to catch and consume: arthropods, reptiles, amphibians, birds, and even small mammals. In fact, theyll even eat other tarantulas given the opportunity. Theres an old joke that tarantula keepers tell to illustrate this point: Q: What do you get when you put two small tarantulas in a terrarium?A: One big tarantula. Life Cycle Tarantulas engage in sexual reproduction, although the male transfers his sperm indirectly. When hes ready to mate, the male tarantula constructs a silken sperm web and deposits his sperm there. He then sucks the sperm back up with his pedipalps, filling special sperm storage organs. Only then is he ready to find a mate. A male tarantula will travel at night in search of a receptive female. In many tarantula species, the male and female engage in courtship rituals before mating. They may dance or drum or quiver to prove their worth to one another. When the female appears willing, the male approaches and inserts his pedipalps into her genital opening, and releases his sperm. He then quickly retreats to avoid being eaten. Female tarantulas usually wrap her eggs in silk, creating a protective egg sac which she may suspend in her burrow or move as environmental conditions change. In most tarantula species, the young emerge from the egg sac as bald, immobile postembryo, which require a few more weeks to darken and molt into their first instar stage. Tarantulas are long-lived, and typically take years to reach sexual maturity. Female tarantulas can live twenty years or more, while the males  life expectancy is closer to seven years. Special Behaviors and Defenses Although people often fear tarantulas, these big, hairy spiders are actually quite harmless. They arent likely to bite unless mishandled, and their venom isnt all that potent if they do. Tarantulas do, however, defend themselves if threatened. If they sense danger, many tarantulas will rear up on their hind legs, and extend their front legs and palpi in a kind of put up your dukes posture. Although they dont possess the means to inflict much damage on their attackers, this threatening posture is often enough to spook a potential predator. New World tarantulas employ a surprising defensive behavior – they fling urticating hairs plucked from their abdomens at the offenders face. These fine fibers can irritate the eyes and respiratory passages of predators, stopping them in their tracks. Even tarantula keepers need to be cautious when handling pet tarantulas. One tarantula owner in the UK was surprised when his eye doctor told him he had dozens of tiny hairs lodged in his eyeballs, and they were the cause of his discomfort and light sensitivity. Range and Distribution Tarantulas live in terrestrial habitats throughout the world, on every continent except Antarctica. Worldwide, about 900 species of tarantulas occur. Just 57 tarantula species inhabit the southwestern U.S. (according to Borror and DeLongs Introduction to the Study of Insects, 7th edition). Sources Bugs Rule!

The Black Cat free essay sample

The man I married was tender at heart and was particularly fond of animals. When he was a child, he was pampered with many different pets, and was at his happiest when feeding and taking care of them. However, his affection for animals grew as he got older and I noticed it. We acquired birds, gold fish, a nice dog, rabbits, a small monkey, and a cat named Pluto. Pluto was a beautiful, large, black cat and was my husband’s favorite pet and playmate. He would follow his only caretaker around the house and would even follow him out into the streets if he was allowed. Their friendship had last a few years, until he unfortunately became an alcoholic. Day by day, he grew more moody, irritable, and more regardless of others feelings. He began using vulgar language towards me and even started mistreating me. He even neglected his beloved pets when they got in his way. We will write a custom essay sample on The Black Cat or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Pluto, however, was an exception because my husband tried his best to restrain himself from ill-treating him. Nevertheless, eventually poor Pluto also began to feel his wrath. In the middle of one night, I had awoken and made my way out of our bedroom after noticing that my husband was still not home. I looked out the front window and saw him walking unsteadily in the direction of the house and our black cat making his way towards the drunken man. Suddenly, I witnessed him violently snatching Pluto and the frightened cat accidently biting his hand. In horror, I watched as my once-loving husband became possessed by anger. With malice showing in his eyes, he grabbed the unfortunate pet by the throat and pulled out his pocket knife. My hand rose to my mouth in fear and I gasped as the ill-fated cat had one of his eyes cut from his socket. With tears threatening to spill down my face, I hurriedly made my way back to the bedroom and feigned sleep. The last thing I wanted was to experience the other side of my husband’s rage. My thoughts prevented me from real sleep as I thought about how much the man that is currently unconscious on the couch has changed, considering everything that is now on his conscience. As expected, the cat slowly healed, but now the creature was petrified when my husband went anywhere near him. One morning, while making my way home rom the market, I noticed something hanging from the tree in front of our home. As I got closer, realization struck me and the groceries dropped out of my hands and on to the dirt path. There was Pluto hanging from a noose from a branch on the tree. I was frozen for what seemed to be hours, but were merely minutes, before I gathered myself and made my way into my house. Terrified by the cold blooded murder my husband committed, I decided not to say a word to him about anything. That very same night, I was awoken by my husband and looked around to find a fire blazing in every direction. As we were struggling to get out of our room, I saw a small black figure in the corner of my eye, later concluding that it was our precious cat that was thrown through the window by someone attempting to wake us. With much difficulty, my husband and I, along with our servant, escaped the flaming house, which would soon be in ruins. One day, as I was preparing dinner, my husband came home with a content face. That is when I noticed the large black cat purring and rubbing against his legs. My mood suddenly uplifted and I bent down to pet and caress it. This new pet automatically made itself at home, and it greatly reminded me of Pluto. It was almost as big as him and closely resembled him, except for a patch of white nearly covering its entire breast. Unfortunately, like Pluto, it also was deprived of an eye, and that made me fonder of it. It was very affectionate of my husband, and it seemed to bring back a bit of happiness into the household. The beautiful cat followed the same habits as Pluto had, including following its founder around. However, after a while I noticed my husband growing annoyed by it yet again. He tried his best to avoid it at all costs so he would not get the chance to strike and abuse it. My husband seemed to be somewhat frightened by the creature every time it would approach him and even when it would simply show love. After a while, he became very cold-hearted and forlorn, but I just remained quiet and patient. The old building in which we were forced to inhabit in replacement of our home had a cellar under it. This cellar contained coal and other questionable junk from past residents. One day, after my husband realized that we had run out of coal, I accompanied him down to the creepy room. As we made our way down, I noticed that the cat had followed us and swooped down to pet it before continuing behind my husband. Unfortunately, I did not notice the cat making its way past me and towards the man. Suddenly, the poor creature got in the way of the husband’s feet, almost throwing him headlong. The enraged man picked up an axe, but before he could do anything he would regret, I stopped his arm to thwart him from swinging towards the cat. Only after looking in his eyes, which were full of contempt and malice, did I realize my mistake. Everything slowed down as I saw a flash of the axe making its way towards me and finally coming in contact with my skull, making everything go dark.

The Facts of Life Essay Example

The Facts of Life Essay Running Head: THE FACTS OF LIFE. Love, Marriage, Children, Ect†¦ Amanda Seigley Harford Community College Abstract Being a little older now, a freshman in college, I knew that soon I will be facing the marriage/family lifestyle before I know it. I wanted to prepare myself for what was coming in my future so I had a better understanding of what goes on. During this course, while reading the text, I was analyzing myself on how I related by doing the many scales, inventories and discussions within the class. I was able to find out that being married was not that easy. There are so many things to take into account before getting married, such as culture, different views and the different roles that will be played throughout the whole marriage. I think I can say that from taking this course I have been looked marriage and having a family in a new perspective than I had done before. I know I don’t want to rush into anything and let everything take its own course, but I can’t wait to have a family of my own. The Beginning of It All Marriage has many hidden aspects behind just the exchanging of vows. You have definitions of, frameworks, many concepts and gender role socialization.

Marriage and the Family The definition of a marriage is a legal relationship that binds a man and a woman together for reproduction and the subsequent care and socialization of children (Knox Schacht, 2008). I have never been married but I have got the chance to watch my parents have a successful one. I believe that my parents are the definition of a marriage and I think they have done a fine job raising my sister, my brother and I. The definition of a family is a group of two or more persons related by blood, marriage or adoption. There are many types of families but I think the one that best fits my family is the modern family type. My mom and my dad both have worked full time since they’ve been married, and have been able to support their family in doing so. Some people may say that having two parents who work will experience a loss of support, love and may cause delinquent behavior. I don’t believe that is the case at all in my family. My siblings and I both have gotten all the love and attention we needed, and we were brought up in a good family environment. Frameworks There are four different frameworks to describe marriage and the family. They are theoretical, social exchange, family life course development, and structural function framework. Based on the definitions of these I believe that my family was built off the theoretical framework, as well as most of the families in the world, and that I am the result of social exchange framework. Gender Role Socialization Gender roles are the social norms that we are expected to do by society as in male and female behavior. This gets into further detail when you talk about gender role socialization. From society we learn almost everything we know, from attitudes, values, beliefs and behaviors and we adapt to what we’re supposed to do. Such as women can come off moody, easily embarrassed and men are competitive, sarcastic and sexual (Knox Schacht, 2008). There are many positive and negative things that are included in these social norms for both males and females. I myself fit into some of these categories for the negative such as, negative body image and for the positive keeping relationships on track. I’m like every other girl who watches T. V. and see the skinny actresses and wishes, â€Å"Man I wish I could have a body like that†, but I know that I’m not the only one out there that does that. From my experience with men and my current boyfriend I can pinpoint the most common negative and positive norms. For the negative it would have to be limited expression of emotions and fear of intimacy, and for the positive initiating a relationship and greater available pool of potential partners (Knox Schacht, 2008). The men are more likely to ask a woman out then a woman ask the man out, and every girl has probably noticed the amount of women one guy has been with, because lets face it, their easier at it then we are. I did the relationship involvement scale, which I found out that I am very involved in my relationship now. That’s one of the social norms for a woman is the level you’re involved and I think I’m doing a good job of following those social norms. Half Way There Dating and Cohabitation To some people love is a wonderful thing, to others they hate it, but to me, I’m in the middle. Love and every other emotion consist of three parts: a behavior/and or action, a thought and a reaction such as a heart beating faster when that special person is around. Men and women both have different views and thoughts on love. But before you get to love, dating comes first. I haven’t yet been able to live with any of my boyfriends but I have had over night stays and week long trips. I feel as though cohabitating should wait until the engagement or even later. You learn so much from a person by living with them, that I don’t really like the idea of waiting until marriage to live with someone. I have dated my fair share of men, and I feel as though ever women does, is that their all the same. I did the relationship dynamic scale and got a 12, which is the highest which gives me the green light towards a good relationship. Right now I’m in a wonderful relationship with my boyfriend of almost 2 years, and I hope many more years to come. Our love style is more Eros, and we’re in the romantic stage, right now. Jealously gets a hold of me sometimes but its normal, I think. The love attitudes scale showed I was more realistic then romantic when it came to love, which I think is correct. I want things to be more on the real side so I’m never left wondering. Mating Mating may sound like something animals do, but humans do it also, in a different way. We tend to select out mate based on intelligence, education, and background. Selecting a mate then may lead to alternative life styles, such as, staying single, being a single parent by choice, and also having a mate of the same sex. The involved couple’s inventory was a good way for me and my partner to look at what we have to offer each other. We compared the same questions that were important to use to see how we’re a like. I enjoyed spending this time just learning about him, and seeing why I chose him. It came down to us being on the same level with marriage, family, and careers. Multiculturalism I and my partner come from different backgrounds, which is the result of multiculturalism. This plays a huge role in almost everyone’s life. Multiculturalism is something that consists of many cultures in society. My background includes, Polish, Irish, Indian and German, so I’m a mix of a little bit of everything. Since my dad is almost full Polish and my mom’s a mix of the others they were both brought up different based on their cultures. Now my partner is a mix of some other different things such as German, Italian, and a few others. The way he was raised is completely different from the way I was raised, but we’re learning to get a long well. We both have different views on the way to raise children and to have careers. This happens in almost every relationship and all you have to do is communicate with one another and compromise. Communication Communication is the key to success. From doing the Supportive Communication Scale and relating it to my relationship, I found out that I and my partner have good communication. We take time everyday to sit down with out the T. V. on or anything distracting us and just talk about anything and everything. When we get into arguments that a different story. We both try to avoid each other to get away from the situation, which hurts or relationship. Communication also plays a big role in sexuality, especially non-verbal communication. Each gender looks at sexuality in a different perspective. Children and Parenting Blended Families Talking about sexuality leads to the next topic on children, parenting, and blended families. There are many factors that go into how to raise a child. Such as, the wiring of the brain, genetics, institutional differences, societal influences and peer influences (Knox Schacht, 2008). I believe that the way my parents raised I and my siblings were based off of the way they were raised. My mother came from a strict home with her father being a cop and her mother being a school teacher, she also had three other siblings. Since my mom was brought up in a strict environment, she reversed her parenting to being a laid back mom. My dad was the opposite; he came from a laid back family, now my dad is the opposite in being very strict towards us. My family is somewhat what you would call a blended family. My dad was married once before my mom and had one daughter, which was way before my sister, my brother and I. So I have a step sister, and she has a step mother. Getting Older Divorce I have never experienced any sort of divorce except from my friend’s point of view. I’m one of the lucky ones whose parents have stayed married, and not for the wrong reasons. From seeing some of my closest friends go through divorces, I’m glad I have never gone through it. My friends had blamed the divorce on themselves, instead of seeing that it had nothing to do with them. There are many factors that make up a divorce, and one of them is not the children. Today in American 40%-50% of all marriages end in divorce (Knox Schacht, 2008). Sometimes is not because they want to, it’s because they have to. More divorces are brought on because the spouse cheats on the other, or it’s because they are in an abusive relationship. Violence, Abuse, Neglect The Abusive Behavior inventory reveled that I was not in an abusive relationship, which I already knew, and trust me if I was, I would have left a long time ago. Relationship violence is a pattern of behavior in which one partner uses fear and intimidation to establish power and control over the other partner, often including the threat or use of violence. This abuse happens when one person believes they are entitled to control another† (Meggs ,Margaret L. 2003). I am a walking example of that, being physically and emotionally abused in my last relationship. I didn’t think I would be a ble to get out of that relationship, so I ended up staying for two years until I finally got the courage to leave him. It was hard but it had to be done. Although I have been a victim of abuse, I’ve never been neglected. Most neglect happens in younger children and elderly people, since they are the easiest to neglect and the most attention needed. Luckily I have never seen or been around anyone that has been neglected. Stress and Older Age Stress comes into play a lot whether you’re at an older age or not. I’m only 18 and I experience more stress than I should, from going to school full time and working full time. There are a lot of things that I try to relieve my stress such as exercise, or snuggling on the couch and reading a good book. With older age, comes more stress if you’re not careful. There has been an increase in grandparents parenting their grandchildren due to the alternative lifestyles that we have now today. There are gender differences in views of marriage and dealing with losses, when we talk about older age. Older aged men view marriage as idealistic while older aged women view marriage as more realistic with disagreements (Knox Schacht, 2008). Summary There has been a great deal of knowledge that I have taken in throughout this course, from marriage to getting older and being a grandparent. Marriage is not as simple as every one takes it out to be, and that’s the major thing I learned in this course. A family is hard to keep together if you don’t try to make it work, and there are just little things that can affect a marriage or a family. Bibliography ReSPONSE, Meggs ,Margaret L. (2003).
