TOP 10 ANIMAL ENCOUNTERS

The Top 3

Hawksbill Turtles | Cozumel, Mexico

This island’s windward side is a critical nesting ground for hawksbill sea turtles May to October. To protect them, as well as the loggerhead turtles that also lay their eggs on this coast, the Punta Sur Park Turtle Salvation Program was founded in 2000, making its goal to record egg layings and mark nests. Their efforts protect turtles and make it easier for tourists to participate in hatchling releases. This is one of the main reasons that divers encounter green sea turtles nearly every time they giant-stride into the waters off Cozumel. The other is that the reefs are covered in sponges, one of the staples of the hawksbill diet. Because of this, when divers come face to face with a turtle, odds are good it’ll be eating — or will be full from eating, and thus relaxed and more open to longer face-to-beak time.

Green Sea Turtles | Oahu, Hawaii

Hawaii’s honu, or sea turtles, may be smaller than their Caribbean counterparts, but what they lack in size, they more than make up for in numbers. If it’s sunny, many shorelines and lava-rock outcroppings fill with dozens of honu, and any dive site is good for sightings of at least two or more.

Pacific Manta Rays | Kona, Hawaii

Dive operators visit three sites off the Big Island where they shine massive underwater lights at night to attract plankton, which lures in manta rays. On average, 11 show up, each with a wingspan of 12 feet or greater. And keep your eyes peeled in the day for Pacific mantas cruising by in the blue.
