What Eats Turtles? Predators of Eggs, Hatchlings, and Adults

Even with tough shells, turtles have many natural enemies. Eggs and hatchlings face the most danger, while adults have fewer predators. This guide shows what eats turtles across freshwater, sea, and land habitats and how to protect pet turtles at home.

What Eats Freshwater Turtles

Freshwater turtles are smaller than most sea turtles, so a wider range of animals can prey on them. Risk changes with life stage. Eggs and hatchlings are most vulnerable on land. In water, young turtles must avoid fish, snakes, birds, and mammals. Adults have fewer predators, but large alligators, big fish, snapping turtles, and some mammals can still attack.

Map Turtles (Graptemys)

False map turtle sitting on a branch (Graptemys pseudogeographica) — False map turtle (*G. pseudogeographica*)

Common pet species include northern map, Ouachita map, false map, and Mississippi map. In the wild, typical predators are:

Eggs raccoons, red foxes, otters, fly larvae
Emerging hatchlings on land crows, grackles, gulls, herons, blackbirds
Hatchlings in water pike, catfish, bass

As pets, keep map turtles away from unsupervised dogs and cats.

Musk and Mud Turtles (Kinosternidae)

Common musk turtle in Illinois (Sternotherus odoratus) — Common musk turtle (*Sternotherus odoratus*)

Adults are well defended and release a strong musk, so most predation targets nests and small juveniles.

Eggs and hatchlings raccoons, skunks, water snakes, largemouth bass, bullfrogs, other turtles, alligators

Slider Turtles (Trachemys scripta)

Red eared sliders stacked on a log — Red eared sliders

Red eared, yellow bellied, and Cumberland sliders meet many predators, especially when young.

Eggs and hatchlings raccoons, foxes, opossums, crows, gulls, cats, dogs, snakes
In water catfish, gar, largemouth bass, otters, alligators
Adults large alligators and humans in some regions

Cooters (Pseudemys)

Missouri River Cooter (Pseudemys concinna metteri) — Missouri River cooter

Eggs and hatchlings raccoons, opossums, foxes, crows, herons, fire ants
In water otters, large fish, alligators
Adults humans and alligators can attack large individuals

Box Turtles (Terrapene)

Ornate box turtle in grass — Ornate box turtle

Adults can fully close their hinged shells, so predators focus on small juveniles.

Eggs and young raccoons, opossums, skunks, coyotes, snakes

Softshell Turtles (Apalone in North America)

Smooth softshell turtle basking — Smooth softshell

Eggs raccoons, foxes, skunks, crows, bears
Juveniles otters, eagles, herons, water snakes, snapping turtles, alligators
Adults larger alligators and humans in some areas

Painted Turtles (Chrysemys picta)

Eastern painted turtle on a log — Eastern painted turtle

Eggs and young raccoons, foxes, minks, otters

What Eats Sea Turtles

Adult sea turtles are large and fast. They cannot pull into their shells, so flippers and head are exposed. Big sharks and orcas can attack adults. Eggs and hatchlings suffer the highest losses on nesting beaches and during the sprint to the surf.

Leatherback (Dermochelys coriacea)

Leatherback turtle nesting — Leatherback nesting

Eggs raccoons, pigs, dogs, monitor lizards, mongooses, coatis, ghost crabs, shorebirds, humans
Hatchlings gulls, frigatebirds, raptors, crabs, fish
Subadults and adults large sharks, orcas

Hawksbill (Eretmochelys imbricata)

Hawksbill sea turtle underwater — Hawksbill at a reef

Eggs humans, dogs, raccoons, rats
Hatchlings octopus, crocodiles, ghost crabs, groupers, gulls, sharks, dogs, humans
Subadults and adults sharks, crocodiles, octopus, humans

Green Sea Turtle (Chelonia mydas)

Green sea turtle feeding on seagrass — Green sea turtle

Eggs humans, dogs, foxes, golden jackals, jaguars
Hatchlings crabs, crocodiles, sharks
Subadults and adults sharks, humans

Loggerhead (Caretta caretta)

Loggerhead sea turtle swimming — Loggerhead at depth

Eggs raccoons, dogs, hogs, foxes
Hatchlings ants, armadillos, crabs, crows, gulls, frigatebirds, rats, opossums, jackals, small cats, bears in some regions
Subadults and adults sharks, humans

Kemp’s Ridley and Olive Ridley (Lepidochelys)

Kemp's Ridley nesting — Ridley nesting event

Eggs humans, dogs, raccoons
Hatchlings seabirds, crabs, sharks, orcas, humans
Subadults and adults tiger sharks, orcas, humans

Flatback (Natator depressus)

Closeup of flatback sea turtle — Flatback sea turtle

Eggs foxes, dogs, pigs
Hatchlings crabs, birds, small crocodiles near river mouths
Subadults and adults sharks, orcas, humans

What Eats Tortoises

Group of baby marginated tortoises — Baby tortoises are the most vulnerable

Adults are well protected by heavy shells and a full withdrawal. Eggs and hatchlings face the most risk. Predators vary by region.

Hatchlings and Eggs

Raccoons, boars, foxes, coyotes, feral dogs, feral cats, birds, crabs, and humans dig up nests and raid newly emerged hatchlings.

Adults

North America coyotes, bobcats, badgers, ravens, eagles, gila monsters, fire ants, mountain lions, humans
Mediterranean foxes, wild boars, magpies, badgers, hedgehogs, rats, snakes, humans
Africa mongooses, foxes, coyotes in introduced areas, humans

How to Protect Pet Turtles

Captive turtles are safe from most wild predators, but dogs, cats, raccoons, and other opportunists can still injure them. Use these safeguards indoors and outdoors.

Indoors

Use a locking screen lid on aquariums so cats cannot reach in. Choose a screen that clamps to the rim and still allows light.
Keep dogs and cats out of the turtle room unless you supervise closely.
Secure cords and intake grates so a spooked turtle cannot get stuck underwater.

Outdoors

Build a predator resistant pen with walls that cannot be dug under or climbed. Add a wire lid for smaller species.
Cover ponds with sturdy mesh at night if raccoons or herons visit.
Remove attractants like open trash and pet food that bring raccoons and foxes.

FAQs

What eats turtles in ponds and lakes

Western pond turtles basking on a log — Pond turtles share water with many predators

Large fish such as bass and pike, water snakes, otters, herons, gulls, raccoons, snapping turtles, and alligators prey on eggs, hatchlings, and sometimes small juveniles. Adults are less likely to be taken except by very large alligators or snapping turtles.

What eats turtles in the ocean

Lemon shark swimming in blue water — Sharks are major sea turtle predators

Hatchlings are eaten by seabirds, fish, crabs, and crocodiles in estuaries. Subadults and adults face tiger sharks and other big requiem sharks and orcas in some areas.

Can a shark bite through a turtle shell

Large sharks can bite through the shells of small turtles and sometimes injure adults. The largest adults are difficult targets, but flippers and soft tissue remain exposed.

Where do turtles sit in the food chain

Many turtles are mid to high level predators in their habitats. Large snapping turtles are near the top in freshwater. Adult green sea turtles are herbivores that still face occasional attacks from apex predators like tiger sharks.

Can snakes and dogs eat turtles

Yes. Water snakes will take small mud and musk turtles and other hatchlings. Dogs often raid nests and can injure pet turtles with powerful jaws. Learn about dogs and turtles and cats and turtles so you can reduce risk at home.

The Bottom Line

Turtles face many predators, especially before they reach adulthood. In the wild this is part of a natural balance. In captivity the balance is your responsibility. Use secure lids, safe enclosures, and simple night checks to protect your pets. If you have tips or questions about predators and turtle safety, share them in the comments.
