Is the Leatherback Sea Turtle Going Extinct? Status, Traits, Threats & How to Help (Publisher-Re

Scientific name: Dermochelys coriacea
Common names: Leatherback, Lute turtle
Global Red List: IUCN — Vulnerable (VU) overall; some regional populations are far worse (e.g., Eastern Pacific listed as Critically Endangered)
Trade controls: CITES Appendix I (international commercial trade prohibited)

1) Quick answer: is it going extinct?

• Globally: the leatherback is currently Vulnerable, with an overall declining trend.

• Regionally: trajectories differ a lot.

• Pacific leatherbacks—especially in the Eastern Pacific—have collapsed over recent decades and could face functional extinction within ~30 years in parts of their range without stronger protection.

• Some Atlantic populations are comparatively more stable but still face serious pressures.

• Numbers in context: Historical estimates in the early 1980s suggested around ~115,000 individuals globally; conservative recent estimates often cite roughly 20,000–30,000 (true totals are uncertain because highly migratory sea turtles are hard to census).

• Law & enforcement: Most range states ban taking, trading, or eating leatherbacks and their eggs and protect key nesting beaches and turtle-safe fishing practices.

2) Identification & biology

Size & appearance

• The largest sea turtle on Earth: adults reach 2–2.5 m shell length and typically 250–700 kg (exceptionally larger).

• No hard scutes: unlike hard-shell sea turtles, the leatherback’s carapace is a thick, flexible, leathery shell with seven longitudinal ridges, giving a semi-cylindrical profile—the source of its name.

• Very long fore flippers up to ~2.7 m span aid long-distance, energy-efficient swimming.

• Coloration: dark overall with white or pinkish speckling; females often show a pink spot on the crown.

That “scary mouth” (and why it matters)

• Leatherbacks do not have teeth. The mouth, throat, and esophagus are lined with keratinized backward-pointing papillae that grip slippery jellyfish and move them down the throat—perfect for a jelly diet.

Diving, thermoregulation & lifespan

• Deep diver: routinely dives hundreds of meters; records approach ~1,000 m.

• Gigantothermy: despite being ectotherms, leatherbacks maintain body temperatures up to ~10–18 °C above seawater via large body size, counter-current heat exchange, and metabolic heat—allowing them to forage in cool waters.

• Longevity: estimated ~75–80 years; late maturity (~10–15 years).

Diet & ecological role

• Primarily jellyfish, plus zooplanktonic crustaceans, small mollusks, and fish eggs.

• By controlling jellyfish, leatherbacks help stabilize coastal ecosystems and nursery areas for fisheries.

Reproduction & natal homing

• Mating occurs at sea; females return every 2–4 years to the same or nearby natal beaches to nest.

• A season may include 4–10 clutches of ~80–100 eggs each, ~9–10 days apart.

• Very high hatchling mortality: eggs and hatchlings face intense predation and human disturbance; only a small fraction survive to adulthood.

3) Why the decline? The main threats

1. Bycatch in fisheries — longlines, gillnets, and trawls can cause entanglement, drowning, and severe injury.

2. Plastic pollution — leatherbacks mistake bags and film for jellyfish, leading to blockages, starvation, and infection.

3. Egg poaching & illegal trade — persists in some regions due to customs and black markets.

4. Nesting-beach degradation — artificial lighting, vehicles, shoreline hardening, tourism trampling reduce hatching success; sea-level rise and stronger storms erode beaches.

5. Vessel strikes — risk is high in busy coastal corridors.

6. Climate change — temperature-dependent sex determination means warmer sands skew sex ratios, threatening long-term stability.

4) What you (and your community) can do

As a beachgoer / traveler

• Use turtle-friendly lighting (low, warm, downward-directed); avoid bright lights at night.

• Do not touch or move nesting females or hatchlings; keep a respectful distance and follow local guide instructions.

• Clean up lines, nets, and trash; avoid releasing balloons.

• Check local rules before driving on beaches; never drive over dune or nesting zones.

As a consumer

• Refuse turtle products and eggs; support traceable fisheries and gear that reduces bycatch (e.g., TEDs—Turtle Excluder Devices, circle hooks, adjusted soak depth/time).

• Cut single-use plastics and join coastal cleanups.

Community & policy level

• Back seasonal beach closures, dark-sky coastal zones, and habitat restoration.

• Support patrols, enforcement, public education, and monitoring (nest counts, beach mapping).

5) Quick FAQ

Is the leatherback “endangered” or “vulnerable”?

• Globally it’s Vulnerable; some regional populations (notably the Eastern Pacific) are Critically Endangered. Status depends on scale and population.

Why does its mouth look full of spikes?

• Those are keratinized papillae, not teeth—an adaptation for holding and swallowing jellyfish.

What should I do if I encounter a nesting turtle or hatchlings?

• Keep your distance, no bright lights, no touching. If you find a nest or disturbance, contact local conservation staff.

6) Other high-profile threatened animals (examples)

• Bees (key pollinator groups at risk)

• Snow Leopard, Iberian Lynx, White Rhino

• Axolotl (Ambystoma mexicanum)

• Saiga Antelope, Sumatran Orangutan

• Blue Whale, dolphins, Vaquita (CR)

• Purple Frog, among others

Closing

The leatherback—our ocean-roaming jellyfish hunter—is also a living barometer of plastic waste, bycatch, and coastal management. If we reduce bycatch and plastics and protect dark, quiet nesting beaches, this ancient mariner can keep returning to our shores for generations.
