Greenland sharks, which are also known as gurry sharks or grey sharks, tend to live long lives. As the longest-living vertebrate on the planet, they can swim around the ocean for up to 400 years and don't reach sexual maturity until they're 150.
A lobster's brain is located in its throat, its nervous system in its abdomen, its teeth in its stomach and its kidneys in its head. It also hears using its legs, tastes with its feet, and tends to favor one front limb, meaning they can be right-clawed or left-clawed.
