Seals: Cute Yet Vicious

Seals, otherwise known as Pinnipeds, are marine mammals that are commonly located on coastlines and cold waters. They can mainly be found in the Arctic and Antarctic waters but, some species can survive in warm waters such as the Mediterranean and Caribbean Monk seals. Other than being admired for their looks and movements, Seals are very well adapted to evade predators and survive extreme environments.

One of the seal’s most known predators is sharks and whales. These aquatic animals are designed to swim fast through the water to viciously attach and catch their prey. So, the Seal had to adapt and become even faster than them. One way this has been done is by evolution moving external structures internally. The ear flaps of the Seal have moved internally and the genitalia of the Seal has adapted retract into the body. This allows the Seal to swim faster by decreasing their drag in the water. Seals also have a very unique dive response. This response makes their heartbeat slow and directs oxygen-rich blood to vital organs such as the brain and heart.

Seals can grow to be many different sizes based on their species. On average from all species of seals, the weight of a male is about 370 pounds and 6 feet long. Females tend to be a little smaller but, tend to live about 10 years longer.

Seals may seem nice but, they are actually very vicious. They are carnivores that primary diet includes fish. However, there have been documented Seal attach on humans as well as many Seal attach on Seals. So, if you ever see one of these amazing marine creatures, make sure to keep your distance.
