The Galapagos
shark, also known as the grey reef whaler, is an aggressive
requiem shark that is dark gray on top and has an off-white
belly. Its tail has a black edge. There is a ridge running
between the dorsal fins (the fins on the shark's back).
The Galapagos shark was named in 1905 from specimens
found near the Galapagos Islands (in the Pacific Ocean
off the coast of Ecuador).
