Definition: Conocetus is a type of marine mammal in the family Balaenoptera, which includes whales and dolphins. It was originally known as "the whale shark" due to its distinctive white skin and teeth that resemble those of a whale. They are characterized by their large size, streamlined body shape, and ability to dive deep into the ocean. Conocetuses are found in both open and closed ocean environments, with some species living in saltwater habitats while others inhabit fresh water.
