What Is an Eagle Ray? Meet Cozumel’s Winter Visitor
The spotted eagle ray (Aetobatus narinari) is a diamond-shaped ray with long, graceful wings and a striking pattern of white spots scattered across a dark back. Every pattern is unique, giving each ray its own “fingerprint.” They glide through the water with slow, sweeping fin movements that look like they’re literally flying beneath the waves — one reason divers love them so much.
Adult spotted eagle rays are pretty large, achieving a body width of up to 10.8 feet (3.3 m). With their tail fully intact, their total length can measure 16.4 feet (5 m), and their maximum reported weight is 507 pounds (230 kg). They’re ovoviviparous, meaning the embryos develop inside eggs that hatch within the mother, and she gives birth to live young. Sadly, eagle rays are now considered near threatened on the IUCN Red List of Threatened Species.
Eagle rays use their pointed snout to forage in sand, searching for clams, conch, crabs, and small invertebrates. They give birth to live young, and though they normally travel alone, winter brings something extraordinary to Cozumel: groups of eagle rays gliding together through blue water. A group of eagle rays is called a fever, a perfect name for the thrill divers feel when they appear.

Where to See Eagle Rays in Cozumel
While eagle rays can appear almost anywhere during the winter, these reefs are known as the hot spots:
Cantarel (Eagle Ray Wall)
The crown jewel of eagle ray season in Cozumel, Cantarel is famous for sightings of multiple rays flying along the wall in formation. Strong currents make this an advanced dive, but the rewards are spectacular. There are only a few dive centers in Cozumel that make trips there because it is a long trip, and only advanced divers are qualified to dive there due to the powerful currents on that reef.
Santa Rosa Wall
A Cozumel classic. Winter visitors frequently see eagle rays cruising the drop-off as they drift along. Intermediate to advanced level divers. There are strong currents and a deep wall drop-off.
Punta Tunich
Fast currents, excellent drift, and regular winter encounters make Punta Tunich a top dive site during eagle ray season. Intermediate to advanced divers recommended.
La Francesa
Shallower and calmer, ideal for divers who prefer a relaxed drift while still hoping to encounter rays. This dive site is suitable for divers of all levels.
Villa Blanca Reef
Villa Blanca Reef is located in front of Sand Dollar Sports Dive Center in Cozumel. There is a shallow reef and a deeper reef with a wall dive. This reef is a corridor between the northern and southern reefs so it is not uncommon to see eagle rays that are moving between reefs.
