Leatherback Turtle
Dermochelys coriacea · Marine reptile, family Dermochelyidae
The leatherback barely seems like a turtle at all. There is no hard shell, just a ridged carapace of black, leathery skin flecked with white, streamlined like a seed pod, hung with the longest front flippers in the family. It is a deep-ocean animal on a jellyfish economy, warm-blooded enough in practice to cruise off Nova Scotia and Norway, and it crosses entire oceans between nesting beaches and feeding grounds. Divers almost never meet one by design; the realistic encounter is a nesting female (an armored rowboat heaving up a tropical beach by night) or a heart-stopping pass in open water during a baitball season. List it among the ocean's privileges, not its itineraries.

Onları anlamak
Habitat: The open ocean; a pelagic wanderer that dives past 1,000 m for jellyfish and comes ashore only to nest
Dağılım: The widest range of any reptile, from tropical nesting beaches to sub-polar feeding grounds in both hemispheres
Davranış: A warm-bodied ocean nomad: gigantothermy and specialized circulation let it hunt jellyfish in cold, deep water no other turtle tolerates. It almost never lingers where divers are; encounters are brief, awe-struck crossings in blue water or the regulated privilege of watching a female nest at night.
Diyet: Jellyfish and other gelatinous animals almost exclusively, swallowed past backward-pointing throat spines
Boyut: tipik olarak yaklaşık 1.5 m; şu ana kadar belgelendi 1.8 m (carapace length; the largest turtle alive, commonly 300–500 kg, with exceptional individuals larger still).
Yanında nasıl davranılır
In-water: keep distance and never touch or impede. It will not stop for you anyway. On nesting beaches: permitted guided tours only, red or no lights, no flash, stay behind the guide, and never handle eggs or hatchlings.
Koruma
Vulnerable globally with Pacific subpopulations in severe decline; egg harvest, longline bycatch, and plastic bags mistaken for jellyfish are the persistent killers. Beach protection in the Atlantic has produced real recoveries.
