Since then, sharks have experienced major radiations in size, diet, body form, environment, and more. They’ve evolved into various forms, some unrecognizable from sharks both modern and ancient. Despite what most people think, there is a large diversity in sharks today, including skates and rays.…

    These entities are strict undulators that utilize either one of three modes of locomotion: anguilliform, carangiform, and thunniform. Anguilliform swimmers, such as nurse sharks, have elongated bodies in which they use their entire trunk and tail to move, such that, more than one wave is present (Maia, Wilga. and Lauder, 2012). Carangiform swimmers, such as thesher Sharks, use the retral half of their body in less than one wave. Sharks that dwell near the surface of open waters are often classified as such swimmers. Thunniform swimmers, such as the Great White Shark, only utilize their thick tail and caudal peduncle move, creating strong, high velocity…

Even though sharks don't have a bony skeleton like many other fish, they are still categorized with other vertebrates in the Phylum Chordata. The reason you can find shark teeth so easily is because their teeth do not have roots so they fall out within a week. However, sharks have replacements arranged in rows and a new one can move in within one day to take the old one’s place. Sharks have 5 to 15 rows of teeth in each jaw, with most having five rows.…

The surface of a shark’s jaws has an extra support in the form of tiny hexagonal plates called tesserae. Tesserae are calcium salt deposits which gives sharks cartilage more strength. There is often just one layer of tesserae, but larger sharks like the great white shark have three or more layers.…
