US Scuba Diver Bitten by Crocodile in Cozumel Waters
A US scuba diver was bitten by a crocodile while swimming in the waters off Cozumel, Mexico, prompting renewed safety warnings for divers in the area.
A US scuba diver suffered a crocodile bite while diving in the waters off Cozumel, Mexico, according to a report published by DeeperBlue.com on April 17, 2026. The incident underscores a little-discussed hazard in one of the world's most popular Caribbean dive destinations.
Cozumel is widely celebrated for its crystal-clear visibility, abundant coral formations, and proximity to the Mesoamerican Barrier Reef — the second-largest coral reef system on the planet. However, the island's coastal mangroves and inland lagoons are home to the American crocodile (Crocodylus acutus), a protected species that occasionally ventures into nearshore marine environments.
Crocodile encounters in Cozumel's dive sites are rare but not unprecedented. The species is an opportunistic predator that may investigate unfamiliar objects — or swimmers — in its territory. Divers operating close to mangrove edges or shallow lagoon entrances face the highest potential for contact.
Local dive operators are encouraging divers to stay informed about current wildlife advisories before entering the water. Recommended precautions include avoiding dive sites adjacent to mangroves at dawn and dusk, when crocodiles are most active, and immediately alerting divemasters if a crocodile is spotted in the water.
The injured diver received medical attention following the incident. Authorities in Quintana Roo state are investigating and have issued guidance to local operators to reinforce safety briefings.
Dive operators in Cozumel have long maintained strong safety records, but wildlife-related incidents serve as a reminder that the ocean remains a wild environment. Divers are advised to consult their dive operator and check local advisories before each dive.
