An animal with a backbone. Vertebrates evolved during the Cambrian period, over 500 million years ago. Other vertebrates include the amphibians, reptiles, birds, and mammals. Sharks are vertebrates. Some sharks are viviparous.
Some whales have teeth, others have baleen that filters small animals out of the water.
It is a filter feeder and sieves enormous amounts of plankton to eat through its gills as it swims. It is not closely related to the oceanic whitetip shark. It is a sluggish, slender, and potentially dangerous bottom feeder, hunting at night in reefs. It has pointed teeth flanked by cusps. They rest by day, frequently in caves or under rock or coral outcroppings.
