Whales are large mammals living in the sea. Like humans, they breathe with their lungs.
There are many types of whales. Whether the whales have teeth or not would determine what the type of food they eat.
As higher animals living in the sea, whales also need to sleep just like humans.
A whale can eat about 4000 kilograms of krill every day, and the amount excreted after passing through the digestive tract should not be small.
Whales have adapted to the high pressure environment of the deep ocean. The organs, tissues and certain functions of whales have also undergone tremendous changes.
Whales are experts in long-distance communication. They will have different acoustic characteristics to send signals at different depths of the ocean.
Whales are endothermic, or warm-blooded mammals. Endothermic animals refer to animals that can regulate their own body temperature in zoology.
We all know that most land animals originated in the ocean. However, some marine animals originated on land, the most famous example is whales.
