Why do whales get stuck on beaches?
“Every time [the whale] then tries to dive, it can’t equalize the pressure,” Robinson says. Unable to dive, the whale cannot hunt and so becomes both malnourished and dehydrated, because it gets water from its food. Weakened, it will drift with the current and, eventually, end up on the shore.
Why are pilot whales stranded?
They usually occur in highly social species such as pilot and melon-headed whales. With their herding instinct, the entire group will stay together even if one is sick or compromised, which sometimes causes them to strand while trying to support a distressed individual.
Do whales suffocate themselves?
It is actually rare for a marine mammal to “drown,” as they won’t inhale underwater; but they do suffocate from a lack of air. Being born underwater can cause problems for newborn whale and dolphin calves. And necropsies sometimes show that an animal never gets to the surface to take its first breath of air.
Why can’t whales survive on land?
Whales can only survive a few hours on land. They breathe the air just fine. The problem is that their fat holds in too much heat. When the water is not there to absorb the heat, they die.

How did the pilot whales get back into the water?
The additional whales were found in a part of the harbor where the water is a dark tannin color — so they may have been stranded, washed back into the water, then back into the bay, making them more difficult to detect, Deka said.
