Where Ancient Mariners Come to Life
Sea turtles have swam the world’s oceans for over 100 million years — they watched dinosaurs come and go, and they’re still here. At Sea Turtle History, we’re passionate about sharing their stories: the science, the legends, the threats they face, and the reasons they continue to captivate us.
Whether you’re a marine biologist, a conservationist, a student, or simply someone who loves the ocean, you’ll find well-researched, engaging content here — from species profiles and nesting habits to cultural symbolism and the latest conservation breakthroughs.

How to Identify a Sea Turtle
Spot the differences between the seven living species — from shell patterns to scale counts.
With only seven species of sea turtles swimming the world’s oceans today, each one is distinct — but telling them apart takes practice. Here’s a quick primer on what makes each species unique, from the leatherback’s lack of a hard shell to the hawksbill’s ornate scutes.
1. Leatherback — The Giant
The Leatherback is the largest of all sea turtles, reaching up to 2,000 pounds. Instead of a hard shell, it has a leathery, rubbery carapace with seven distinct ridges. They are deep-diving specialists, feeding almost exclusively on jellyfish, and can migrate across entire ocean basins.
2. Green Turtle — The Grazer
Named for the greenish colour of its body fat (not its shell), the Green Sea Turtle is the only herbivorous species as an adult, grazing on seagrass and algae. Its shell is smooth and heart-shaped, with a single pair of prefrontal scales between its eyes.
3. Hawksbill — The Beauty
With a sharply curved beak and overlapping shell scutes, the Hawksbill is one of the most visually striking species. They are coral reef specialists, feeding on sponges and invertebrates, and are critically endangered due to the tortoiseshell trade.
4. Loggerhead — The Workhorse
Loggerheads have large heads and powerful jaws, adapted for crushing hard-shelled prey like clams and crabs. They are the most common species in the Mediterranean and the southeastern United States, and they are known for their long-distance migrations.
5. Olive & Kemp’s Ridley — The Social Swimmers
These smaller, greyish-green turtles are known for their synchronised nesting events called arribadas. Olive Ridleys are found in tropical waters worldwide, while Kemp’s Ridley is the rarest and most endangered, nesting almost exclusively on a single beach in Mexico.
6. Flatback — The Australian
The Flatback is the only species with a truly flat shell, and it is found only in the waters around Australia, Indonesia, and Papua New Guinea. It has a very limited range and is the least studied of all sea turtle species.
Quick tip: When identifying a sea turtle, look at the shell shape, scale patterns on the head, and the beak. Habitat and region also help narrow down the species. Our full identification guide goes deeper with photos and distribution maps.

Frequently Asked
Answers to the questions we hear most from our readers.
How many sea turtle species are there?
There are seven living species of sea turtles: Leatherback, Green, Hawksbill, Loggerhead, Olive Ridley, Kemp’s Ridley, and Flatback. They are found in all of the world’s oceans except the polar regions.
Are all sea turtles endangered?
Six of the seven species are classified as threatened or endangered under the IUCN Red List. The Flatback is listed as “Data Deficient,” but it is still considered vulnerable. The greatest threats include habitat loss, bycatch, plastic pollution, and climate change.
How long do sea turtles live?
Sea turtles can live for 50 to 100 years or more, though exact lifespans vary by species and are difficult to measure in the wild. Some estimates suggest leatherbacks may live up to 80–100 years.
Where do sea turtles nest?
Sea turtles nest on sandy beaches in tropical and subtropical regions around the world. Major nesting sites include Costa Rica, Mexico, Florida, Australia, Hawaii, and the Mediterranean. Each species has distinct nesting preferences and migratory routes.
What do sea turtles eat?
Diet varies by species. Green turtles are primarily herbivorous, eating seagrass and algae. Leatherbacks eat jellyfish. Hawksbills eat sponges and invertebrates. Loggerheads and ridleys are omnivorous, eating crustaceans, mollusks, and other marine life.
How can I help protect sea turtles?
You can help by reducing plastic use, supporting sustainable seafood choices, avoiding single-use plastics, participating in beach cleanups, donating to conservation organisations, and being mindful when visiting nesting beaches — for example, keeping lights off and giving turtles space.
