Dichotomous Key

 

BKJ. (2013) Bolivian Gray Titi Monkey Poster. Chicago: GCE.

 

This is a project for my Population math and science class. The purpose of this project was to make a dichotomous key of an animal of our choice. I learned a lot about what a dichotomous key is and how we classify animals. I am proud of all the work I did in this project because I spent time and energy creating a product that summarizes everything I have learned so far in Population. You can read the information from my board below. 

 

Bolivian Gray Titi Monkeys are small primates with thick, fluffy fur and tails that can reach up to 19 inches in length. As their name implies, their fur is often gray, although it can range to orangish-brown in color, particularly on the belly and chest, with white ear tufts.

Bolivian Gray Titi Monkeys are also called White Eared Titi Monkeys because of the distinct markings on their ears. In the wild, one of their main predators is the ornate Hawk-Eagle.  The monkeys also camouflage well. To spot the monkeys, look for movements among the branches or as they hop from tree to tree.

Titi Monkeys are small to medium size primates, typically about the size of a rabbit, (research by Hersh Kovitz 1990-95) they do not have Prehensile tails and are not sexually dimorphic.  Pleage and body coloration differs between species of Titi Monkeys, but all species typically have thick fur or are somewhat shaggy in appearance. All species can be different in pelage, and body pelage-extremity can come in a variety of colors, such as: pale brown, black, brown, gray, orange, red, yellow, or a combination of the colors. The tail is longer than the head and body combined.
