Mako Shark Toy
Not only are makos the fastest shark species, but researchers believe they may be the smartest. Mako sharks have one of the largest brain to body ratios of all shark species, prompting researches to attempt to quantify their level of intelligence. Scientists discovered that makos were relatively fast learners, and able to quickly determine threats from non-threats. Sadly, the mako is currently classified as vulnerable and its population numbers have decreased in the last 10 years.
