Answer 1

Answer:

pls mark me as brainilist

Explanation:

When a dolphin or whale dies, the air in its body may disappear or even be replaced by water, causing it to sink. A few species of whale and dolphin (including the right whale and the sperm whale) appear to be positively buoyant even when dead, which causes them to float

Answer 2

Answer:

As they have gills in their body to breathe air in and to breathe out the air .

So ,when they have to sink them in water they usually fill up that whole (gills ) with water and so that they can easily sink in water ..

When they have to float they release that water put for ease to float ..
