Galapagos shark
The Galapagos shark resembles the Grey reef shark, but can be distinguished by its more slender body, and by the slightly rounded tip on the first dorsal fin. The Galapagos shark also strongly resembles the Dusky shark, but has a much more straighter first dorsal fin, and it has larger teeth than the Dusky shark. However, this can be difficult to distinguish without direct comparison of the two species. The Galapagos shark has a brownish-grey upper body, and a white belly. A white stripe can sometimes be seen on the sides of the shark.  Their pectoral fins are solid grey with slightly dusky tips.
