Herbivorous Sea Turtles
Let’s dive into the munchies of your favorite oceanic vegans: Green Sea Turtles, Flatback Sea Turtles, and Olive Ridley Sea Turtles.
Green Sea Turtles
Green Sea Turtles (Chelonia mydas) are basically the salad lovers of the sea, chomping mostly on greens like seagrasses, algae, and seaweed. They’ve got cool, jagged jaws perfect for biting into these tough leaves.
- Main Menu: Seagrasses, algae, and seaweed
- Snack Options: Jellyfish, sponges, even salps in the neighborhood waters
- Feeding Habits: The big ones stick to the greens, while the kiddos start out on a seafood diet, feasting on meat before they realize vegetarian’s where it’s at (SeaWorld, Oliver Ridley Project)
| Green Sea Turtles Diet | Proportion (%) |
|---|---|
| Seagrasses and Algae | 80 |
| Jellyfish and Sponges | 20 |
Flatback Sea Turtles
Flatback Sea Turtles (Natator depressus) aren’t just about that leafy life; they like a bit of variety, nibbling mostly on seagrasses and algae.
- Food Favorites: Seagrasses, algae
- Side Dishes: Small invertebrates, soft corals occasionally
- Eating Spots: They prefer the coastal buffet where seagrasses grow aplenty.
Olive Ridley Sea Turtles
Now, Olive Ridley Sea Turtles (Lepidochelys olivacea) mix things up. They’re sort of the rebels of the group, diving into both plant life and the occasional critters.
- Usual Grub: Algae, seagrasses
- Additional Bites: Jellyfish, small crustaceans, mollusks
- Dining Preferences: They suck up whatever’s good, whether it’s in the green or seafood section, depending on what’s fresh.

Carnivorous Sea Turtles
Carnivorous sea turtles like getting their fill from a menu filled with animal goodies. Let’s chew over what three well-known meat-loving turtle species eat: Leatherback, Loggerhead, and Hawksbill Sea Turtles.
Leatherback Sea Turtles
Leatherback sea turtles (Dermochelys coriacea) are true connoisseurs of the squishy kind, earning the nickname “gelatinivores.” Their favorite meals include jellies and soft-bodied critters like tunicates and sea squirts (See Turtles). This squishy diet definitely makes them stand out in the turtle crowd.
| Food Type | Part of Their Meal Plan |
|---|---|
| Jellies | 85% |
| Tunicates | 10% |
| Sea Squirts | 5% |
Their throats are specially built to keep a grip on those slippery suckers, making chowing down on their wobbly prey a breeze.
Loggerhead Sea Turtles
Once they grow up, Loggerhead sea turtles (Caretta caretta), are meat-eaters with a knack for cracking tough shells. With jaws like vices, they munch on benthic critters like crabs and whelks (See Turtles).
| Meal | Share of the Feast |
|---|---|
| Crabs | 40% |
| Conchs & Whelks | 35% |
| Horseshoe Crabs | 25% |
Their hefty noggins and strong jaws are just the thing for busting through hard shells as if they were crackers.
Hawksbill Sea Turtles
Hawksbill sea turtles (Eretmochelys imbricata) are picky eaters opting mainly for sponges. Their sharp beaks are perfect for snagging sponges from coral nooks (See Turtles). While they’re not just sponge-exclusive, these oceanic snacks make up most of their diet.
| Snacks | Diet Portion |
|---|---|
| Sponges | 90% |
| Soft Corals | 5% |
| Anemones & Others | 5% |
Hawksbills help keep reefs in check by keeping sponge populations under control.

Omnivorous Sea Turtles
Sea turtles, especially the omnivorous ones, enjoy a smorgasbord buffet of plant and animal treats. Let’s get into the grub choices of Kemp’s Ridley Sea Turtles, and see how other sea turtles mix and match their meals depending on where they’re hanging out and what’s on the menu.
Kemp’s Ridley Sea Turtles
Kemp’s Ridley Sea Turtles (Lepidochelys kempii) loves a bit of everything on their fork. They go gobbling down swimming crabs, jellyfish, and a splash of juicy mollusks (Smithsonian Ocean). These gluttons of the ocean are typically chilling in shallow coastal zones filled with mud, sand, or gravel, often digging around in seagrass for dessert.
| Food Item | Percentage of Diet |
|---|---|
| Swimming Crabs | 50% |
| Jellyfish | 30% |
| Mollusks | 20% |
Dietary Variability Among Sea Turtles
Each sea turtle sports its own culinary tastes. Whether they’re munching on meat, veggies, or both, their feeding habits are driven by their ‘hood, sea vibes, and what groceries are available.
Take green turtles (Chelonia mydas), for instance: they graze on seagrass and algae but don’t mind tossing in some sponges, salps, and even jellyfish for a balanced meal.
Loggerheads, olive ridleys, and Kemp’s ridleys, on the other hand, are kitted out with tough jaws for smashing crabs, shells, and shrubs alike.
Factors Influencing Sea Turtle Diets
What exactly makes a sea turtle pick its dinner, you ask? Well, a few things:
-
Habitat: Whether they’re kicking it by the coast or drifting the deep blue, location decides what food is up for grabs. Those Kemp’s Ridleys relish the easy access to crabs and mollusks in the shallows.
-
Jaw Structure: The chomper setup they’ve got can sway the menu. Loggerheads with their sturdy gnashers are just right for tackling tough, crunchy meals.
-
Availability of Food Sources: What’s on hand changes with the seasons and tides—jellyfish and seagrasses wax and wane like, well, the lunar cycle (ocean currents and all that jazz).
