Habitat & Fossil Locality

Shallow coastal waters (with seagrass beds and marine algae) of tropical, subtropical, and temperate seas; hatchlings live in the open ocean

💡 Everyday Comparisons for Size, Mass & Speed

💡 A weight of 181 kg is slightly heavier than two traditional Korean sacks of rice (80 kg each) combined (Comparison).
💡 In the waters off Jeju, sea turtles caught in fishing nets or washed ashore are recorded every year. From 2013 to 2022, 24 out of 38 individuals were green seaturtles.
💡 NOAA cites fishery bycatch and ingesting or becoming entangled in marine debris as major threats to the green seaturtle.

📖 1. Overview

The green seaturtle is a large sea turtle widely distributed across tropical, subtropical, and temperate seas, nesting on beaches in more than 80 countries.

🦴 2. Anatomy & Morphology

Full-grown adults measure 3–4 feet (about 0.9–1.2 m) in body length and weigh 250–400 pounds (about 113–181 kg). Newly hatched young head out to the open ocean and spend several years there.

🔍 3. Ecology & Behavior

As the only herbivorous sea turtle species, it feeds mainly on seagrasses and marine algae. Females reach maturity at 25–35 years of age and swim hundreds to thousands of miles every 2–5 years to return to their nesting beaches.

🇰🇷 4. Connection to Korea

It is designated as a protected marine species in Korea. Among 38 sea turtles caught in fishing nets or washed ashore in the waters off Jeju from 2013 to 2022, green seaturtles were the most numerous at 24 individuals, and the waters around the Korean Peninsula mark the northern limit of the western Pacific green seaturtle distribution.
