3 Animals That Are Endangered

Brown spider monkey


Female brown spider monkeys and male brown spider monkeys are the same length - about 1.2 meters long. The females weigh up to 7.5 kilograms, whereas the males only weigh up to 7.3 kilograms. Their scientific name is “Ateles hybridus”. They usually have light brown eyes. Some of them have blue eyes, but that is unusual. They have a white belly and a long white patch on their forehead. Brown spider monkeys are found in the forests of north western Venezuela and the north of Columbia. The brown spider monkey has been listed on the 25 most endangered animals list six times already. Its diet is mostly fruit-based, but it also eats leaves, flowers and seeds. Brown spider monkeys require a primary lowland forest to thrive, most likely to be seen at the top of canopies. They are called brown spider monkeys because of the habit of using their tail as another limb to hold on to three branches when moving around, hence the name brown spider monkey. The population continues to decline because of deforestation and the continued hunt for their meat and fur. There are only 250 left in the world.


Vaquita

Female vaquitas are 1.5 meters long, whilst the males of the species grow up to 1.45 meters. While the weight of male vaquitas is unknown, female vaquitas can reach a weight of 50 kilograms. For comparison: dolphins weigh 150-250 kilograms. Its scientific name is

"Phocoena sinus” which means “purpose of a gulf”. Male vaquitas have larger fins than their female counterparts. Their body is rather small but powerful and sturdy. They have a round face and no beak. There are black patches around their eyes and lips, their teeth are jagged and knifelike. They are found in the northern part of the Gulf of California, Mexico. They enjoy feasting on small fish, shrimp and octopuses. The vaquita has the smallest geographical range of any marine animal. There are only 10 left of them. They are endangered due to illegal fishing and because they share waters with the Totoaba fish. Fishermen fish the Totoaba fish, and whilst they do so the vaquitas get stuck in the net.


Siamese crocodile



Both male and female Siamese crocodiles weigh the same – up to 120 kilograms – and are the same length. They have a wide range of habitats, such as low rivers, streams, lakes, marshes and swamps. They have a smooth and broad snout and elevated bony crests behind each of the eyes. Their colours range between different variations of green, but the most common is olive green. They mainly feed on fish and snakes, but they also enjoy feeding on amphibians and small mammals. They are under threat from human habitat disruption which has made 99% of the original amount go extinct. The Siamese crocodile is the least studied crocodile in the world. It is native to Indonesia, Brunei, East Malaysia, Laos, Cambodia, Vietnam and Thailand. They are called Siamese crocodiles, because they are originally from Siam, known as “Thailand” since 1939. They are also hunted for their valuable skin. There are only 1,000 Siamese crocodiles left in the world.
