Leatherback Sea Turtle

Snapshot

The world’s largest turtle — ~4.5–6+ feet, often hundreds of pounds — ridged rubbery shell without hard scutes; jellyfish specialist. Rare but regular in Georgia offshore waters; nesting mainly farther south. Federally Endangered (ESA); IUCN Critically Endangered globally.

Description and identification

SREL: 53–74 in; typically 650–1,200 lb (record >2,000). Smooth rubbery grey-black to bluish shell with seven longitudinal ridges; pink/white blotches common on plastron, flippers, and head. Scissor-like jaws for soft prey. No hard scutes. Males: more concave plastron and longer tails. Nothing else in Georgia waters matches the ridged leatherback profile.

Look-alikes

All hard-shelled sea turtles — scutes and different profiles. Loggerhead, green, hawksbill, and Kemp’s ridley all retain hard carapace scutes; leatherbacks do not.

Range in Georgia

Pelagic worldwide in Atlantic, Pacific, and Indian oceans. Nests in tropics (southeastern Florida, Caribbean, etc.). Georgia: mainly offshore foraging and migration rather than routine nesting.

Habitat preferences

Open-ocean upper layers; deep dives (often hundreds of meters, sometimes deeper) for prey; coastal waters when following jellyfish blooms or breeding. Can maintain body temperature slightly above ambient water, allowing high-latitude foraging unusual for reptiles.

Natural history

Jellyfish predator with extreme dive ability and regional endothermy relative to water temperature. Nest infrequently on tropical beaches; females nest only every several years. Open-ocean biology remains incompletely known. Plastic bags mistaken for jellyfish are a major mortality source — a calm conservation teaching point without fearmongering.

Food preferences

Almost exclusively jellyfish; also tunicates and seaweed. Backward-pointing spines in the mouth and esophagus help swallow soft prey.

Temperament and encounters

ESA Endangered — report sightings and strandings; never approach a nesting or stranded animal without responders. Georgia encounters are mainly offshore or stranding events.

Conservation and legal notes

U.S. federally Endangered rangewide; IUCN Critically Endangered (global IUCN category — keep labels distinct). Threats: fishing-gear entanglement, propeller strikes, nesting-habitat loss, and plastic ingestion. Older estimates cited tens of thousands of nesting females worldwide — status remains dire.

All sea turtles in U.S. waters are federally protected under the Endangered Species Act. It is illegal to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect them, or to disturb nests. Report strandings and nesting activity through current Georgia DNR / USFWS channels. Do not invent statutes. Beach lighting, coastal development, bycatch, and marine debris remain major threats. Educational observation from a distance is the default.

If you meet one

Watch from a respectful distance on the beach or from shore. Never approach nesting females, hatchlings, or nests; never shine lights at turtles; never dig in marked or unmarked nest areas. If you find a stranded, injured, or dead sea turtle, report it through current Georgia DNR / stranding-network contacts rather than attempting rescue yourself.
