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 their breath for long periods. [57] Dive duration largely depends on activity.
Some turtles, especially those specialized in diving, are highly reliant on cloacal respiration during dives. [2] They accomplish this by having a pair of accessory air bladders connected to the cloaca which can absorb oxygen from the water.
Sea turtles spend almost all their lives submerged, but must breathe air for the oxygen needed to meet the demands of vigorous activity. With a single explosive exhalation and rapid inhalation, sea turtles can quickly replace the air in their lungs. The lungs permit a rapid exchange of oxygen and prevent gases from being trapped during deep dives.
Sea turtles must surface to breathe, but not as often as you think. Diving and hunting sea turtles can stay down anywhere from five to forty minutes. While asleep, sea turtles can stay down for ...
The seven existing species of sea turtles are the green sea turtle, loggerhead sea turtle, Kemp's ridley sea turtle, olive ridley sea turtle, hawksbill sea turtle, flatback sea turtle, and leatherback sea turtle. [107] As air-breathing reptiles, sea turtles must surface to breathe.
Turtles, like other reptiles, breathe air, not water. They have lungs, not gills like fish, and so even if they live mostly in the water, they need to come up to the surface to breathe now and again.
Aquatic turtles mount in water, [88] [89] and female sea turtles support the mounting male while swimming and diving. [90] During copulation, the male turtle aligns his tail with the female's so he can insert his penis into her cloaca. [91] Some female turtles can store sperm from multiple males and their egg clutches can have multiple sires ...
Turtles can be found anywhere, from local ponds and the deep, blue sea to an aquarium tank in your bedroom. These aquatic, semiaquatic or terrestrial creatures are easily recognized thanks to ...
