Females lay about 300 to 400 eggs per cocoon, and about four cocoon's every summer. The black widow spider is nocturnal, it hunts and moves about at night. It is a very dangerous spider. In fact its venom is 15 times more dangerous than that of a rattlesnake. It is an invertebrate animal belonging to the arachnid family, to the class of the arthropods.
A howlers roar can be heard from as much as 2 miles away and both males and females howl. The howler monkey howls for many reasons usually to warn other fellow howler monkeys of danger, male howlers howl to claim their territory, and also to look for potential mates. These primates move particularly slow for primates and mostly uses their tails to grab and hang off of branches while using its hands for grabbing food. Their tails are strong enough to support the monkey's entire body weight, also their first 2 fingers of each hand are set apart and are opposable to the other three allowing them to easily grab tree branches and other objects like food. Howlers are herbivores and usually stay in the canopy where they get most of their food which is mostly leaves and fruits.
Human induced fires are a main threat. They set fires to fields in order to improve fertility for livestock grazing, killing ticks and other insects, making scrap metals visible to collect, and stimulating fern growth. According to the World Wildlife Foundation (2014), “indiscriminate logging, forest fires, and land conversion for farming are the main causes”. Leopards are quite solitude creatures, so not having forests to take cover in is taxing on their existence. An area of about 5,000 km^2 is the last viable habitat in Russia for the Amur leopards (World Wildlife Foundation, 2014).
The babies nurse until 8-9 months old, then they are weaned nutritionally, but not socially for up to two years of age. The pandas are sometimes forced to go hungry because of the reduced food supply in their environment due to human influences. As adults, giant pandas have black and white pigmentation patches, the black part covering their eyes, arms, ears, and legs, while the rest of their bodies are white. Giant pandas are 2-3 feet tall at the shoulder, on four legs, and reach 4-6 feet long. Males can weigh up to 250 lb in the wild, but females rarely reach 220lb.
Harlow’s experiment i Attachment in Rhesus Monkeys Harlow’s experiment ii Abstract In the past 30 years, the work of Harry Harlow using rhesus monkeys while researching learning was criticized for the cruelty imposed onto animals. He noticed that many young monkeys kept in isolation became distressed when he cleaned out their cages. From there, he went onto researching attachment issues, providing the baby monkeys with surrogate mothers and observing their behavior. While most agree that he contributed to the science of early bonding and perhaps the keys to love, criticism revolves around the issue of using animals for research. This paper examines Harlow’s life and his advances in early development research.
They have special teeth which allow them to get grass low to the gound and then grind it up. They can go long periods of time without water because they have the ability to get moisture from plants. Kangaroos do not hunt for food at all. There are perceived as a pest to farmers for doing damage to their fences and eating their crops. Because of this there are several thousand that are legally shot each year.

Some of the main threats to the survival of this species are: Forest fires Inbreeding Development Lack of political commitment Illegal poaching is another major cause for concern. Amur leopards are targeted for their striking, spotted coat, which can sell for up to $1,000 in parts of southeastern Russia. With less than 40 individuals remaining in the wild, the death of one leopard can have severe consequences for the species as a whole.
A bite to the face or torso or a direct hit into a vein or artery can bring death from paralysis within 20 minutes. An aroused mamba often strikes repeatedly in blurred succession, reputedly fast enough to tag a bird in flight. A tale of colonial times tells of mambas overtaking men on horseback or dropping through chimneys to wipe out whole families. In fact they are among the nimblest of snakes, quicker than a person in thick bush and at times undeniably hostile. Around southern Africa there are loose and eccentric circle of field collectors, bush guides and native people who actually know the creature.
They are perfectly adapted to the tropical rainforest. The Tarsier is a predator, it hunts insects above ground, but only live prey. It hunts based on sound and sight, it has mobile ears that work together to pinpoint the exact location of an insect. So when it rains, it’s harder for the Tarsier to hunt since it ruins the sound adaptation. The Tarsier’s long slender fingers are for the grasping of branches.
The trading of illegal animals is the third most common illegal trading, the first being drugs and the second being human trafficking. Illegal trading of animals is not very well known because illegal trading of drugs and human trafficking is more known because of the media attention it creates. Not being educated is one of the main reasons that many people don’t actually know that the animals that they have just got are illegal where they live. Much of the global trade in these animals is accounted for by tourist souvenirs, traditional medicine and bush meat. The illegal trade for these accounts is becoming more and more common, and the laws just aren’t providing enough enforcement to prevent and stop the illegal trading of animals.
