About this site
Sieto Cocos lies off the coast of Quintana Roo, Mexico, in the Caribbean waters near the Yucatán peninsula. It reaches a maximum depth of around 20 metres and is generally considered an intermediate dive. The site's coral is mostly lobed star coral and thin leaf lettuce coral, with giant anemones scattered across the reef. Divers have also reported a range of reef fish here, including Atlantic blue tang, beaugregay, bluehead and yellowhead wrasse, four-eyed butterflyfish, slippery dicks, and white grunts.
