I plan do do research on and eventually give a presentation on sloths. Sloths are found in Costa Rica as well as in many other countries. Their lifestyle as well as behavior are very interesting and they are an integral part of the ecosystems in which they are found. They are also essential to the existance of other species as will be hilighted in my research paper. I have always been interested in and intrigued by sloths, their niche, and why they are so slow. Finding out why they are so important to their surrounding environments is one of my chief goals for this assignment.
