Brazilian Wandering Spider Research Paper

Their prey includes beetles of the scarabaeidae family , wolf spiders, cockroaches, crickets, and grasshoppers. Grice provides as his evidence that “all of the widow’s prey would find lesser toxins fatal, and there is no particular benefit to killing or harming larger animals” (12). He goes on to say “even natural selection favors the inheritance of useful characteristics that arise from random mutation and tends to extinguish disadvantageous traits” (12). This proves there is no known scientific or rational reason for the venoms high toxins. By providing no logical explanation for the widow’s high virulent venom, Grice leaves the reader with a

According to Primate Info Net, there are seven species of spider monkeys recognized with the Black Spider Monkey included. The Black Spider Monkey is the largest of them all. These adorable monkeys have long, shiny black hair covering their bodies, except for the face, which is red or pink. One thing that makes these monkeys stand out against other monkeys is their long, prehensile (defined as "capable of grasping") tails. With this fifth limb, they have more stability when resting in trees and grasping branches. For extra ease in swinging through the trees, they have an extra mobile shoulder joint. These monkeys are large, but with a slender frame, a "pot belly" and spidery limbs (which is where their name comes from). Male spider monkeys are typically 52-58 cm in length, with their tail can grow to be as long as 72-85 cm by itself. Females are usually 49-62 cm with a tail length of 64-93 cm long.

Although black widow bites can be fatal to young children, most people do survive. If you think a black widow, or any other spider has bitten you, it is always best to remain cautious and to tell an adult. Chapter 20-

The Lycosidae uses its chelicerae to hold its prey before using its venomous fangs into paralysing it. (Nicholas, 2011) Similarly, snakes inject venom quickly into its prey and waits for it to immobilise before digesting it, this adaptation prevents preys from escaping and increases its chance of survival.

The Black Widow is a vilified, venomous, and vile creature. The venomous spiders were discovered in all of the continental United States. However, the Black Widow was not discovered in Hawaii or Alaska, because of the extreme temperatures. The Black Widow received the name “Widow”, because of the myth that the female may eat the male if it comes too near to its web, nonetheless this does not happen regularly. They are also highly venomous, but can only inject a small amount of toxin at a time. The female Black Widow and male Black Widow are tremendously different in size, color, and lifespan. The male lives for approximately two months, whereas the female can live up to three years. The male is long, scrawny, and brown

It is well known that some female insects and spiders eat the males during and after mating and the praying mantis and the black widow spider are two examples. Scientists have always believed that the males were eaten because they weren’t able to get away. The male it was assumed would try to survive to breed again the female simply considered the male as food. The two were seen as antagonists in a real-life “battle of the sexes.”

When examining the frequency and duration of the web vibrations being produced by Stenolemus bituberus and the prey, the researchers observed that the assassin bugs created web vibrations similar to the low-amplitude web movements generated by exhausted prey. Additionally, the researchers found that the assassin bugs never generated the distinctive vibration caused by prey landing on the web, nor did they create the high amplitude long duration web vibrations caused by the wing beats of struggling prey2. They also found that prey continuously generated high amplitude vibrations as they struggled in the web, while the leaf only generated one large wavelength from its initial impact2.The researchers also found that the spiders generally had no response to the leaf, and that the female spiders responded to the vibrations of the courting male by assuming a copulatory stance2. However, the courting male spiders generated a repeated web vibration not observed from the other forms web stimuli, suggesting a method by which female spiders discriminate courting male spiders from the other web

Gaboon vipers also one of the few snakes that has its own world record! They have the longest fangs of any other snake on Earth! Their fangs can measure up to an amazing 2 inches in length. Since their fangs are so long they also have a unique way of attacking prey. Like most snakes they sit and wait for their prey to wander by. However, unlike other snakes once they strike at

The German cockroach that lives in Brazil is a small species. It is about 1.1-1.6 troublesome insect. The Wolf Spider that lives in Brazil is like a Tarantula. They do not spin webs. They burrow in the ground. Its body is covered in hair and it is venomous.

I’ve recently learned many spiders eat their dead. I wonder if there is a specific spider who has eaten more than the rest, a leader of sorts, the Ultimate Spider. I believe this spider could have been the dreaded Ultimate Spider. It’s only a matter of time until he returns for revenge.

The Brazilian wandering spiders originate from South America and tend to sneak into bananas before they are shipped to countries like the

The African Black Mamba(Dendroaspis polylepis) :the black mamba is found in southern and Eastern Africa mostly in the savanna. It travels at a speed of

The Coquerel's Sifaka are another example from this era. They originated from the forests of Northwest Madagascar. They eat mostly leaves, flowers and fruits. They are the second largest lemurs. Sifakas have long legs, which enable them to jump from tree to tree in an upright position. Another primate belonging to this era is the Galago. They are bushed babies varying from cat to rat size. The most striking features of the Galago are its huge eyes, long tail and large hind legs. Brain size is average and their vision and hearing are well adapted to nocturnal insect hunting. Their limbs enable them to make rapid leaps from branch to branch. They claim territory with there scent leaving smelly footprints.

Tarantulas bite and venom might sound interesting, but can be quite devastating. Even tarantulas can't kill you, they can be very unfriendly once it gets out. When it does bite the venom moves through the blood spreading out a pain that us humans call today muscle cramps, and chest pain. Although scientists don't believe you should use this drug for muscle cramps, and chest pain, but because opioids are the only thing they can use.

The country's coastline is covered with national reserves designed to preserve the unique plants and animals that draw visitors from all over the world. The Madagascar Spiny Thicket is an unusual region in the south of the country. It is a cross between a forest and a desert. Most of the plants in this region are found only in Madagascar. Some trees grow tall with long, sharp spines and no branches, these are octopus trees. The famous Baobab tree has a fat trunk and stubby branches. This helps them to store lots of water along with their leaves that help store water as well. All of these characteristics help the plant survive for long periods without rain. A Baobab tree can create its own ecosystem and support the life of many different other creatures. It can support mammals all the way to thousands of tiny creatures crawling on its branches. Most birds make a nest in its wide branches, baboons come to eat the fruit. Also bush babies and fruit bats like drink the nectar and they also help pollinate the flowers on the tree. Elephants have been known to whittle down and eat an entire
