Do Sea Turtles Have Teeth?

Sea turtles do not have teeth. Their jaws and mouth structures help them bite, grip or swallow food in other ways. The Florida Museum describes several of these feeding adaptations, including green turtles' serrated jaws and leatherbacks' throat papillae. Florida Museum: turtle adaptations

A beak over the jaws

In hard-shelled sea turtles, a keratin covering forms the beak over the upper and lower jaw bones. Scientists call it the rhamphotheca. Its shape differs between species. Keratin is a structural material; the beak is not a row of teeth joined together. Wyneken's anatomy guide, Rhamphotheca Structure

Imagine three feeding tools:

• Green turtle: serrated edges help cut plant food.
• Hawksbill: a narrow, pointed beak can reach into reef crevices.
• Loggerhead: broad, strong jaw surfaces help crush hard prey.

These comparisons describe structures, not a promise that every turtle eats only one food. Compare the meals in our diet guide.

What are the spikes in a leatherback's mouth?

A leatherback has sharp jaw edges and backward-pointing structures in its mouth and throat that help retain soft prey such as jellyfish and salps. The throat structures are papillae, not teeth. NOAA distinguishes this feeding system from the crushing beaks of turtles that eat hard-bodied prey. NOAA leatherback profile

Look without touching

Toothless does not mean harmless: a strong jaw can still bite. Study photographs or diagrams and give wild animals space. Never put fingers near a turtle's mouth or feed a wild turtle to see how its jaws work.
