Are Tiger Sharks Found In the Waters Around Cozumel? At TopCozumelNews, we help Cozumel tourists plan their trips and activities using information collected on trips to the beautiful island. Cozumel’s marine ecosystem includes sharks, and diving here offers divers an amazing opportunity to observe them in their natural environment. Swimming alongside these powerful predators is both exciting and terrifying – truly an experience not to be missed! Tiger sharks can be identified by their blunt snout, stripes that fade with larger specimens, notched teeth, and distinctive long scythe-like extension of their upper caudal fin – traits only unique to this species.
