Pygmy Marmosets are not as vulnerable as their larger cousins, but only because they are small, highly adaptable and can live in secondary growth. Pygmy Marmosets can also hide in a tree hollow or foliage when predators come near. The major threat is habitat destruction usually by humans, cutting down trees for farms paper mills, and mining, especially threaten them. Although pygmy marmosets are still plentiful in the wild, other types of primates aren’t as lucky, and if we don’t conserve the rainforest/habitat in which they live, soon the pygmy marmosets could become endangered or even extinct. Until the 1970’s Pygmy Marmosets were highly persecuted. They were thought to have yellow fever, therefore, had many tests and other medical research done on them. They were also trapped to keep as pets.

          Boa Constrictors are a threat, usually 10-14 feet long as adults and live in tropical parts of Central and South America. They catch their prey by hanging from a tree branch, then blending in with the background looking like a vine. When their prey goes beneath then they will drop on the unfortunate animal, wrapping itself around the prey and squeezing the breath from it, the prey will suffocate and die. The Boa Constrictor can swallow a creature larger than the size of their head because their jaws unhook at the back allowing them to stretch the jaws extremely wide. Boa’s are not poisonous. Boa Constrictors live in French Guiana, Guyana, Brazil, Peru, and other tropical regions of South America (two types of boa’s live in the southern United States). There are over 50 species of boa’s, ranging in color from bright emerald green to rainbow colors to a camouflaged brown. These snakes eat birds, lizards, and small rodents like mice and pygmy marmosets. In captivity they usually eat dead mice because live ones may attack the snake causing minor harm. Boas give birth to up to 50 young at once. The babies are born alive, not in eggs.
