The Diets of Seals Vary

Seals eat a variety of species, with the majority relying on seafood acquired at sea. However, there are a few species that defy the stereotype.

Leopard seals, for example, rely on hunting penguins and even other seals to make a living. Meanwhile, walruses eat clams and other shellfish that they trace with their incredibly sensitive whiskers before sucking up their muscular lips from the seafloor.

The crabeater seal is an Antarctic pinniped species. On the other hand, these animals do not consume crabs—at least not the ones you might expect. Instead, these seals filter water for Antarctic krill, a small, plentiful crustacean.

Seals Aren’t Usually Dangerous

Generally speaking, seals will not attack humans on purpose or out of nowhere. Although they are highly unusual, there have been a few accounts of seal attacks. Seals aren’t hazardous; even if they bite, they can’t kill you because they’re not venomous or carry rabies. Even though seals are mammals, they are rarely infected with rabies since rabies is more common in terrestrial mammals. Seal bites, however, can spread illnesses, including the infamous ‘seal finger,’ a typical seal bite result.

A Young Seal is Called a Pup

Pups are young seals considered pups from the time they are born until they are weaned around the age of one year.

To survive, the newborn seal must learn to swim and catch food on its own. While learning to hunt for themselves, many baby seals lose nearly half of their body weight.

The adolescent seal stage comes next. The seal will have learned to catch its prey and swim during this stage. So now, all that’s left is to put on some weight to survive the cold, brutal winter.

The adult seal is the last stage of their growth cycle. Seals are considered adults at the age of six and can live for up to thirty years, depending on whether they are male or female.

Badgers, Skunks, and Bears are all Related to Seals

Evolutionary biologists have debated the origins of seals for more than a century. While scientists are confident that pinnipeds descended from land-dwelling predators, they disagree on the exact stages between terrestrial predecessors and present marine mammals. Along with the three subclades of Ursidae (bears), pinnipeds, Mustelidae (weasels, otters, badgers, and relatives), and Mephitidae make up the suborder Caniformia (skunks and stink badgers). A relatively complete skeleton of a novel semi-aquatic carnivore was discovered in 2007 in an early Miocene lake deposit in Nunavut, Canada. It became renowned as an evolutionary link between land animals and seals.

When Seals Dive, their Brain Temperature Falls

During a fifteen-minute dive, hooded seals’ brain temperature dropped by three degrees Celsius, indicating that the brain was using less oxygen. The seals sent cold blood to their brain via their front flippers’ prominent superficial veins, lowering the brain’s oxygen consumption by 15-20%. This significantly increases a seal’s diving capabilities while protecting it from hypoxic harm.

The Baikal Seal is the Only Freshwater Seal in the World

The Baikal seal, one of the smallest true seals, marks the seal’s evolutionary transition from terrestrial to semi-aquatic. Seals most probably spent time in freshwater before moving to the oceans. Lake Baikal, a freshwater lake in Siberia, is home to a diverse range of fascinating animals and is the world’s oldest and deepest lake.
