Carcharocles

Information
Carcharocles megalodon, a shark that owes it's size to the numerous plankton of the recent Cenozoic ocean. Around five million years ago, this shark grew to the length of two school buses and learned to filter feed. It may have been related to the whale shark, basking shark, and the megamouth shark. This shark had to eventually reduce size and give up its teeth as they began to become outcompeted by prehistoric whales, such as the predatory deep-diving Livyatan melvillei, the ancestor of modern-day sperm whales, and the ever-so large baleen whales that were also taking up the krill-loving niche.

Design
Megalodon appears rather similar to todays modern whale shark, but larger and more teeth. Megalodon had a rather large mouth, helpful for filter-feeding larger gulps at a time. It is mainly grey with a light underbelly and white spots on the sides. Megalodon also has relatively large gills and large fins.
