However, sharks are far more than this and play a vital role in the oceans and nature. Their evolution has produced several species with different sizes, anatomies, habits and behaviors. Their classification according to the features such as the fin types, spine, snout and body shape determine the genus and family of each species. For example, the great white shark has the mouth behind its eyes and a large dorsal fin by the middle of its body and a second dorsal fin behind. An angel shark, on the other hand, has a couple of fins in the dorsal area near the tail and a flat nose with the mouth underneath.
The evolutionary features of sharks, not only defined their look but also the adaptations they have to survive in the wild. There are three types of sharks according to the place they live which is closely related to the form and functions of their body. Some sharks dwell at the surface of the ocean and move slowly, other sharks inhabit the pelagic zone and have amazing swimming capabilities and some others stay at the seafloor, in the benthic zone, and move slowly searching for food on the sea floor.
According to those areas where sharks live, there are also specific ways of surviving. Therefore in each of these parts, the prey behave in different ways which led to the developing of the hunting skills that they acquired. Sharks are species belonging to the superorder Selachimorpha. The scientific classification of all sharks is as follows:. The classification continues with eight orders, organized in 37 families which include all the species. This classification includes the most primitive sharks, those with six or seven gill slits, a dorsal fin, and lack of nictitating membranes in their eyes.
This order includes species characterized by having two dorsal fins and five gill slits. Seven families. Gulper sharks. This order includes sharks with a wide flat body and pectoral fins, characteristics that make them similar to rays. The species belonging to this order have a long snout and serrated teeth. It is an order of small sized species with spikes on the front part of their dorsal fins.
The species that belong to this order are also called carpet sharks and have two dorsal fins without spines, and some species feature patterns decorating their skin. Blind sharks. It is the largest order, and its members are also called ground sharks. They have nictitating membranes in their eyes, anal fin, and five gill slits. Eight families. Requiem sharks.

I took four of them into a sixth-grade classroom I was subbing in the other day and they were an instant hit with the kids.
