How do the seals dive down so far with all the pressure and not get squished?
Good Question! The reason these seals do not have the problems that we would at depth is because of their shape (shaped like a football which has advantages of being squished), the fact that they do not have air sinuses like ourselves to get squished, and some other reinforced parts (aveoli in luns for example) that all help keeping these animals diving with little ill effects of pressure.
Do you have a tent or shack or trailer that you sleep in ?
We sleep in "town" but while we are out in the field, we have the abilty to sleep in a fish hut.. its a nice warm hut with sleeping bags and FOOD!!
