Sharks in Puerto Rico

Puerto Rico is home to about 40 species of sharks. This information is not surprising, considering the water surrounding the tropical paradise remains warm year-round, which is ideal for most shark species.

Sharks tend to hang out close to beaches with shallow water and reefs that have a decent supply of food. However, they do not feed on humans and tend to avoid us altogether most times.

Recent Cases of Shark Attacks in Puerto Rico >>



Shark attacks in Puerto Rico are pretty rare. Most occur when the shark mistakes a human on a surfboard for a seal and bites them under this misconception. Other times, they are attracted by the fish captured by anglers and go into a frenzy. In 2021, two surfers were attacked by an unknown shark – possibly a species of hammerhead. This was the first such attack in a decade, the last in 2011. However, it is believed that the shark was aggressively pursuing a stingray and most likely had no intention of attacking the duo.


Several species of sharks are endangered or facing extinction due to loss of habitat and getting caught as bycatch.


Yes, there are places like Cayo Lobito and Mona Island, where nurse sharks live, the coral reefs of Vieques home to tiger and Caribbean reef sharks, and the famous Black Wall dive, inhabited by several species of hammerhead.


Though increasingly rare, great white sharks can be seen in Puerto Rico.
