The Gardeners of Cozumel 💚🐢
This beautiful turtle is a Green Sea Turtle (Chelonia mydas), one of the three species of sea turtles commonly seen around Cozumel. While loggerheads often steal the spotlight with their impressive size, green turtles are the true gardeners of the Caribbean.
If you look closely at this photo, you'll see it enjoying a meal of seagrass. Unlike most other sea turtles, adult green turtles are primarily herbivores. Their powerful jaws are perfectly adapted for cropping underwater meadows, much like cows grazing on land.
But they're doing much more than just feeding.
By constantly trimming the seagrass, green turtles keep these underwater meadows healthy and productive. Fresh, short seagrass grows back stronger, provides shelter for juvenile fish and invertebrates, helps stabilize the sandy bottom, and stores large amounts of carbon. In other words, every grazing turtle helps keep the entire marine ecosystem in balance.
People often ask me how many green turtles live around Cozumel. No one knows the exact number, but the island is home to one of the Caribbean's most important feeding areas for green turtles, and divers encounter them almost every day. It isn't unusual to see several on a single dive, quietly going about their work beneath the waves.
The next time you see a green turtle with a mouthful of seagrass, remember—you aren't just watching lunch. You're watching one of nature's hardest-working underwater gardeners.
