"The Hol Chan Marine Park (Hol Chan is Mayan for Little Channel) is situated north of Caye Caulker. Declared the first marine park in the entire country of Belize, this area has been zone a protected area. Due to its protected status, what was once a depleted fishing area has now been allowed to re-generate.
It's a channel 30 feet deep, with steep coral-lined walls. Hidden in the coral crevices there are Moray Eels, some of the biggest fish around are the Black Groupers, now reaching fairly impressive proportions after being protected from fishermen for several years. They are there all year except spawning time between December and February. As well as the fish (over 500 species of them) there's the crustaceans, from tiny Red- banded Coral Shrimp to the sizeable crayfish Spiny Lobster.
Hol Chan is also full of coral. It's quite an exposed site so only species adapted to strong currents and waves can survive, Elkhorn Coral deeper, other types become more common. Staghorn Coral is next, then Finger and Star Coral. Biggest of all is the boulder-size Brain Coral, with its grooves carefully aligned to funnel away any sediment that could smoother its polyps."
