Whitetip Reef Shark: Slender, White-Tipped, and Mellow

The whitetip reef shark is one of the Pacific's most laid-back sharks — a slim, gray shark with white-tipped fins that often rests quietly under ledges by day. These live mainly around deeper reefs and offshore islands rather than our shallow beach, but they're a classic resident of Costa Rica's Rich Coast. Here's what to know, plus five fun facts.

How to spot the whitetip reef shark near Jacó

You're very unlikely to meet one on a shallow shore snorkel at Playa Mantas — whitetips favor deeper reefs, drop-offs, and offshore islands like the Catalinas and beyond. If you do spot one on a deeper dive or boat trip, look for the bright white tips on the dorsal and tail fins and a slim gray body resting on the bottom. Calm, slow, and best admired from a respectful distance.

5 fun facts about the whitetip reef shark

• White-tipped signature. Bright white tips on its dorsal and upper tail fins make it one of the easiest reef sharks to identify.
• It can rest on the bottom. Unlike many sharks that must swim to breathe, the whitetip can pump water over its gills while lying still under a ledge.
• A night-shift hunter. By day it rests; at night it squeezes into reef crevices to hunt sleeping fish, octopus, and crustaceans.
• Homebody shark. It often uses the same resting spots for years, sticking to a small home range on the reef.
• Shy around people. It's a timid shark that generally keeps its distance from snorkelers and divers, retreating rather than approaching.
