| 説明 | PLEASE, no multi invitations in your comments. DO NOT FEEL YOU HAVE TO COMMENT.Thanks.I was lucky to see this sea turtle on my last day, taken from the shore, resort staff said this was rare to see.Sea turtles are almost always submerged in water, and, therefore, have developed an anaerobic system of respiration. Although all sea turtles breathe air, under dire circumstances they may divert to anaerobic respiration for long periods of time. When surfacing to breathe, a sea turtle can quickly refill its lungs with a single explosive exhalation and rapid inhalation. Their large lungs have adapted to permit rapid exchange of oxygen and to avoid trapping gases during deep dives. However, turtles must emerge while breeding, given the extra level of activity. |
