Pilot whales are big with black bodies and big foreheads.
The animals breathe air, but they can get dehydrated in the sun. Whales are also very heavy. Outside of the water, their own weight can put too much pressure on their organs. Sadly, most beached whales die.
Luckily, experts came to help and saved most of the whales. Scientists aim to learn and help more whales in the future.
