Data Deficient

The Megamouth Shark, otherwise known as wahanui (Megachasma pelagios) is a large deepwater shark that is very rare. Every sighting is numbered. Little is known about the data deficient shark, but it has been assumed that it consumes plankton and Jellies with its mouth wide open.

Behavior Edit

The Megamouth Shark's behavior is little known due to the lack of specimens found, but what we know stems from a single specimen. In 1990, a juvenile Megamouth was found at Dana Point, California. He was 16 feet long, and surprisingly close to the surface. He received a radio tag, which recorded him to have a steep vertical migration in order to track the abundance of plankton around them. In the day, the shark would be recorded at a depth 400-525 feet. As night came, the shark would quickly approach closer to the surface, recorded from a range of 39- 80 feet deep. The shark traveled at a low 1 mph.
