The Nature of a Humpback Whale
These whales are known for their acrobatic "breaching" displays and their long bodies, which contain the animal's long flippers. They often swim upside down near the surface of the water, sometimes just under a boat to be petted. They are also known for singing songs, though they do not vocalize with lungs like humans. Instead, they drum with their flukes on the surface of the water. Let's explore more of their nature. Size and Growth A mature whale is about 39 feet in length and weighs up to 40 tons.
