1. Whales need to breathe air
You likely already know that whales breathe by taking in air though their blowhole.
2. Whales can’t sleep for very long?
This is because they have to remember to go to the surface for air as needed.4. Whale Males are not easy to
3. Whales' brain sleep one half at the time
In order to make sure that whales perform the basic functions to breathe, only one half of their brain will sleep
at a time. This is the only way that they are able to get the amount of rest that they need and still take care of
this function that is necessary for their bodies to survive.
It is common for male whales to be misidentified out there due to the location of their genitals. When they aren’t
in use, these parts of the body are actually tucked inside of a cavity. This allows them to swim faster. Therefore
you do need to really look at other factors before you classify a whale as either male or female.
5. Whales are mammals, calves grow inside their mothers.
Do you know that newborn whales are born fin first which means the back end of their body first? Researchers
believe this is done so that the calf is less likely to drown when it is born. All of their young are born alive
and are able to be cared for immediately after birth.
6. Whales are cetaceans, mammals fully adapted to aquatic life.
Whales are believed to be the only mammals that are able to adapt to the changing environment in the waters. This
is important due to the impact that humans have had on their natural living environment.
7. Whales swim as fast as 30 miles per hour.
Whales can swim at a rate of about 30 miles per hour. However, most people think they are much slower because
they often don’t have to be in such a hurry so they simply glide around the water.
8. Whales have hair.
Most people don’t think that whales have hair but they do. However, it is very thin and very light so unless you
are seeing one up close you wouldn’t think it was there at all.
9. Whales are warm blooded.
Whales are warm blooded mammals so they have to keep a high body temperature. Since they don’t have much hair they
rely on layers of fat called blubber. You will find that the younger whales have more hair than the adults. As a
baby gets older it will develop more blubber and then the hair will start to disappear.
10. Whales are the largest animals in the world.
You likely are aware of the fact that whales can be extremely large. The Blue Whale is the biggest one out there.
Most experts agree that the Blue Whale is the largest mammal that ever been on Earth as well as the loudest. They
can be up to 105 feet long. The smallest whale is the Dwarf Sperm Whale. It is only about 8 feet long.
11. The most dangerous predators for Whales are humans
The only predator that whales have to content with are humans. They aren’t bothered by any other creatures in the
water. However, the changes to their food source, hunting by humans, and even pollution to the waters that they
live in can affect their abilities to survive which is why they continue to try to adapt to the environment that
they are in.
