Photo by @BrianSkerry A Shortfin Mako Shark in New Zealand swims open-mouthed at photographer Brian Skerry. Makos are one of the fastest fish in the sea, capable of bursts up to 60mph and of all shark species they have one of the largest brains, relative to body size. The numbers of makos have declined worldwide due to over fishing and the demand for shark fins. They are currently listed as vulnerable.
After the whale shark, the basking shark is the second largest living fish, and can grow up to 32 feet long. These sharks are often mistaken for plesiosaurs, a group of long-necked, predatory marine reptiles that lived at the time of the dinosaurs
