The Galapagos Shark - Carcharhinus galapagensis is considered one of the larger shark species, growing up to 3-3.5 meters length.
They are also known to feed on other smaller shark species. I was shown footages during a night dive, when the smaller Whitetip Sharks were busy hunting reef fishes, one of the smaller one of around 1 meter was snapped up by a Galapagos Shark and and all eaten up within 10 seconds!
The Galapagos shark is a species of requiem shark, in the family Carcharhinidae, found worldwide. This species favors clear reef environments around oceanic islands, where it is often the most abundant shark species. A large species that often reaches 3.0 m, the Galapagos reef shark has a typical fusiform "reef shark" shape and is very difficult to distinguish from the dusky shark and the grey reef shark.
