Most likely dolphins do not dive very deep though. Many bottlenose dolphins live in fairly shallow water. In the Sarasota Bay area, the dolphins spend a considerable time in waters that are less than 2 meters (7 feet) deep. Other whale and dolphin species are able to dive to much greater depths even.
Ring-tailed lemurs. The order Primates includes humans, apes, monkeys, and prosimians. Many of them may be familiar, but it would not be surprising if you cannot immediately visualize prosimians (like the ring-tailed lemurs in the picture on the right). How many living primate species exist today is not clear.
The difference between great apes and lesser apes is general size. There are two types of lesser apes: gibbons (SE Asia) and siamangs (SE Asia). There are four types of great apes: gorillas (Africa), bonobos (Africa), orangutans (SE Asia), and chimpanzees (Africa).
