Most of these photos were taken on reefs of Akumal (between Cancun and Tulum on the Mayan Riviera). For topside photos of this beautiful part of the world, instead go here.  I have also posted these pictures here, but they are of no better quality; this is all we were working with back then (early 2003).

Algae

Scleractinians (reef-building corals)

Fish

Non-hard coral invertebrates

Miscellaneous underwater shots (inc. turtles, seagrass, and reefs)
