Photo by @BrianSkerry. A Shortfin Mako Shark off the coast of New Zealand swims towards the surface in the late afternoon light. Makos are one of the fastest fish in the sea, capable of speed bursts up to 60mph. Of all shark species they also have one of the largest brains, relative to body size. The numbers of Makos have declined worldwide due to overfishing and the increasing global demand for shark fins. They are currently listed as vulnerable by the IUCN. Learn more about Mako Sharks from the feature story about these impressive animals in the August issue of National Geographic Magazine, @NatGeo.
