Turtles
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.

فهمها
الموئل: The open ocean; a pelagic wanderer that dives past 1,000 m for jellyfish and comes ashore only to nest
النطاق: The widest range of any reptile, from tropical nesting beaches to sub-polar feeding grounds in both hemispheres
السلوك: 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.
النظام الغذائي: Jellyfish and other gelatinous animals almost exclusively, swallowed past backward-pointing throat spines
الحجم: عادةً حوالي 1.5 m; موثَّق حتى عمق 1.8 m (carapace length; the largest turtle alive, commonly 300–500 kg, with exceptional individuals larger still).
كيف تتصرف في حضوره
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.
الحفاظ على البيئة البحرية
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.
