Verde vs. Caguama: Know Your Nesting Species

Two species share our stretch of beach in Akumal, and once you know what to look for, telling them apart is easier than it sounds.

The loggerhead (Caretta caretta), known locally as caguama, is the more frequent nester here. She has a large, blocky head and a reddish-brown carapace, and her tracks show an alternating, asymmetrical gait—you can often spot a slight offset between the left and right flipper marks. Loggerhead clutches average around 100–120 eggs.

The green turtle (Chelonia mydas), or tortuga verde, nests less often on our beach but is common in the seagrass beds just offshore, where adults graze almost exclusively on marine plants—the source of the greenish fat that gives them their name, not their shell color. Her tracks tend to be more symmetrical, with both front flippers moving together in a smoother, more even pattern.

Neither species can be identified from the tracks alone with total certainty—that’s why every nest gets logged with photos and, where possible, direct observation. But learning to read these signs is one of the first skills every SAVE volunteer picks up, and it changes the way you see a beach at night.
