Thermoregulation[edit]Most sea turt

Thermoregulation[edit]
Most sea turtles (those in family Cheloniidae) are poikilotherms.[27] However the leatherback (family dermochelyidae) areendotherms because they can maintain a body temperature 8 °C warmer than the ambient water.[27]
Green sea turtles in the relatively cooler pacific are known haul themselves out of the water on remote islands to bask in the sun.[28] This behavior has only been observed in a few locations including the Galapagos, Hawaii, Europa Island, and parts of Australia.[28]

A green sea turtle breaks the surface to breathe.
Diving physiology[edit]
Sea turtles are air breathing reptiles that have lungs, so they regularly surface to breathe. Sea turtles spend a majority of their time underwater, so they must be able to hold there breath for long periods.[29] Dive duration largely depends on activity. A foraging turtle may typically spend 5 - 40 min under water.[29] While a sleeping sea turtle can remain under water for 4–7 hours.[30][31] Remarkably sea turtle respiration remains aerobic for the vast majority of voluntary dive time.[29][31] When a sea turtle is forcibly submerged (e.g. entangled in a trawl net) there diving endurance is substantially reduced, so they are more susceptible to drowning.[29]
When surfacing to breathe, a sea turtle can quickly refill its lungs with a single explosive exhalation and rapid inhalation. Their large lungs permit rapid exchange of oxygen and avoid trapping gases during deep dives.
Ecology[edit]
Diet[edit]
The loggerhead, Kemp's ridley, olive ridley, hawksbill, flatback, and leatherback sea turtles are omnivorous for their entire life. Omnivorous turtles may eat a wide variety of plant and animal life including, decapods, seagrasses, seaweed, sponges, mollusks, cnidarians, echinoderms, worms and fish.[32][33][34][35]However some species specialize on certain prey.
The diet of green turtles changes with age.[36] Juveniles are omnivorous, but as they mature they become exclusively herbivorous.[33][36] This diet shift has an effect on the green turtle's morphology.[37]
Leatherback turtles feed almost exclusively on jellyfish and helps control jellyfish populations.[38][39]
Hawksbills principally eat sponges, which constitute 70–95% of their diets in the Caribbean.

Ăn tạp rùa có thể ăn nhiều loại thực vật và động vật sống trong đó, decapods, nguên, cỏ biển, bọt biển, động vật thân mềm, cnidarians, echinoderms, sâu và cá.
