On the third day of the Cozumel Expedition, OGL divers explored two new dive sites on deep walls. Moderate currents gently guided the divers past vast expanses of coral and sponge. Highlights from the dive included green moray eels (Gymnothorax funebris), a massive Nassau grouper (Epinephelus striatus)with alarge school of bluestiped grunt (Haemulon sciurus) in tow, Christmas tree worms, (Spirobranchus giganteus) and bearded fireworms, (Hermodice carunculata). In addition to coral reefs, the group explored shallow nearshore sea grass beds with diverse bivalves and of gastropods including the flamboyant flamingo tongue, (Cyphoma gibbosum) with its orange leopard spots. Tomorrow the group heads to Cozumel’s wild north coast.
