The sharks that you run into on these dives are typically caribbean reef sharks ranging between 5 & 7 ft long. They are very impressive looking, but they aren't about to attack a Scuba diver on purpose unless provoked. A 6-ft tall Scuba diver all geared-up is every bit as large as 1 of these sharks. They are not going to mess with you if there is an easier meal to be had.

Exception #1: most shark attacks occur in poor visibility. Caribbean waters are usually clear with visibility ranging from 60 to 100 ft. Not much chance of being bitten.

Exception #2: Scuba divers that 'do' get bitten are usually involved in spear fishing activities. Spear fishermen are warned to suspend their catch at the end of a long leader & NOT clip them to their dive gear where sharks may be encouraged to grab.

This is a Caribbean Reef Shark similar to the type that you see on a shark dive like that described.

The key word there is...”typically.”
