From Wikipedia, the free encyclopedia

Mexico Rocks is a shallow patch reef complex located off the far northern tip of Ambergris Caye, in the Belize Barrier Reef. The site consists of approximately 100 Holocene patch reefs clustered on a Pleistocene ridge of limestone and is composed predominantly of boulder star coral (Montastraea annularis)[1]. The reef has accumulated in shallow water, about 2.5 to 5 metres (8 to 16 ft) deep, over the last 420 years, under static sea level conditions.The site was recommended for designation as a marine preserve in 1978, and was approved in 2015 and is part of the Hol Chan Marine Reserve.[2]

A popular snorkelling and SCUBA diving destination, it is seen as an important addition to the Ambergris Caye's ecotourism attractions.[2]

The Montastraea annularis boulder corals that dominate here are unique to Ambergris Caye's northern lagoon and a rare occurrence in Belize; the only other such patch reefs in the country are located at Glover's Reef.[2] In addition, staghorn coral (Acropora cervicornis) occurs on the ridge's windward and leeward flanks. Thirty species of hard corals have been identified on Mexico Rocks [2] .

The reef is abundant in fish and invertebrate life. Common fish found at Mexico Rocks include Atlantic blue tang (Acanthurus coeruleus), yellowtail snapper (Ocyurus chrysurus), and southern stingray (Dasyatis americana)[3]. Nurse sharks (Ginglymostoma cirratum) and green moray eel (Gymnothorax funebris) are also found on the reef[3]. Spiny Lobster (Pallinuridae), conch (Strombidae), arrow crab (Stenorhynchus seticornis), banded shrimp (Stenopus hispidus)and many sponge species are also found throughout the reef.
