how long can sea turtle hold their breath
Sea turtle 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.[32] Dive duration largely depends on activity. A foraging turtle may typically spend 5–40 min under water[32] while a sleeping sea turtle can remain under water for 4–7 hours.[33][34] Remarkably, sea turtle respiration remains aerobic for the vast majority of voluntary dive time.[32][34] When a sea turtle is forcibly submerged (e.g. entangled in a trawl net) its diving endurance is substantially reduced, so it is more susceptible to drowning.[32]
