107 species are described here, grouped from big animals (sharks, rays, turtles, marine mammals) to the small reef life you only notice when a guide points it out. Each species page lists the dive sites where it has been reported.
We tag every species as common, seasonal or rare: 82 are common, 11 seasonal and 14 rare. That tells you what to expect, and what is a bonus.
Names are linked to the species pages. The most viewed in each group come first.
Sightings are never guaranteed, and seasons shift from year to year. If a particular animal is on your wish list, check its page for where it is reported, then ask the dive center what they are seeing at the moment.
