Discover the marine life in Cancun

The ecosystem in the Caribbean waters is huge!

Cancun’s reef sites are home to hundreds of different species of sea life, these are some of them that you can find

Sea Turtles

They are very common in Cancun and the island of Isla Mujeres.

The three main species of turtles found in and around the area are Green Turtles, they can grow up to 1.5 mts (5ft) long, Hawksbill and Loggerheads. The turtles come up onto Cancun’s beaches during nesting season which is from May to September. It’s very important to leave the nests alone if you come across them.

Manta Rays

They are similar to whale sharks, they are both plankton feeders and are migratory animals.

A giant manta ray can grow up to 9 mts but they tend to be smaller in these waters. They may look intimidating but Manta Rays are harmless and they usually swim amongst the reefs of Cancun or lie dormant on the seabed.


There are about 1,800 species of starfish worldwide and they are in abundance amongst in Cancun and it’s surroundings. They are marine invertebrates, and typically have five arms, though some species have a larger number of arms. Their surface may be smooth, granular or spiny. Many species are brightly coloured in various shades of red or orange, while others are blue, grey or brown.

Most can regenerate damaged parts or lost arms and they can shed arms as a means of defence.

Sea Urchin

Its black or dark purple body is densely covered with short white thorns. It lives in beds of seagrass and occasionally in shallow reefs where it often covers itself with leaves and other debris. In some places, its roe is used in gourmet dishes.


The queen angelfish is one of the most representative species of the Caribbean due to its bright colors.

Blue striped grunts are other of the most common found fish along with Trumpet fish, Yellow Goatfish and Barracuda.

Nurse sharks

They are non-threatening and often seen lying close to the coral reef. They are mainly nocturnal animals, their diet consists of crustaceans and other fish mainly, although they also eat algae and coral.

These are just some marine animals that we can find diving or snorkeling in the waters of Cancun. It is also possible to live this experience, venturing to the Sea trek, a walk by the sea.

No matter what activity you do, we are sure that the marine life in Cancun will enchant you.
