Galapagos Shark, Carcharhinus galapagensis (Snodgrass & Heller, 1905)

Scientific name: Carcharhinus galapagensis

Similar species:
The species looks similar to the Grey Reef Shark. They can be separated by the number of precaudal vertebrae (103-109 vs. 110-121). The Galapagos Shark has a higher, more erect dorsal fin and usually less distinct black markings on the second dorsal fin and lower caudal fin lobe (pers. comm. Dr Clinton Duffy).

Danger to humans

Galapagos Sharks can be aggressive towards divers. Many individuals were encountered during the Kermadec Islands expedition. Most often the sharks appeared to be 'inquisitive' rather than aggressive.
