All the Curiosities of the seals you need to know
1.How the seals are born
They are one of the few species of marine animals that claim to be mammals, that is: they do not lay eggs such as fish or birds (which are oviparous), but the female, when she becomes pregnant, carries the fetus inside itself until it is ready to be born. Like the rest of the mammals, they give birth to their young, the baby seals, and breastfeed them.
2.Focas baby
At birth, baby seals depend on breastfeeding for their mother and acquire their carnivorous habits thanks to the hunt for their parents.These little mammals have a peculiarity that differentiates them from their adulthood: while they are babies, they have a large coat of fur very warm , which is because they do not yet have the thick layer of fat from own adult seals to protect themselves from the cold.
When they become adults, they lose most of this fur , some even completely, depending on the species.fur of baby seals is highly coveted by hunters who act outside the law (since baby seals are in danger of extinction and their hunting is prohibited), who sell it at high prices on the black market for manufacturing coats and other household goods.
3.What do the seals eat
They are carnivores; this means that they only feed on meat , although their diet can be very varied and depends mostly on the breed of seals we are observing.Most feed on crustaceans, cephalopods (octopus, squid...) and fish, however, there are records that some seals have come to eat penguins !, especially elephant seals! or sea elephants.
4.Where the seals live
These mammals tend to live around the coasts (we assume that more than because humans like them is because of the greater presence of crustaceans) and they are found all over the world, but they usually flee to the tropics, because the suitable habitat for them is composed of cold waters.In fact, where most seals are usually found is on the coasts of the North and North poles South.
5.How do seals reproduce
The way of sexual life or relationships" couple "depends mainly on their race : there some seals that, while they do not have young, keep living alone, there are others that are monogamous, that is: they have one partner at a time (and in their case for a lifetime), while cases have also been recorded in the which seals create family nuclei where there is a male and a female harem. The seals reproduce in the same way as the rest of the mammals : carrying out a coitus.
6.More curiosities of seals
Its scientific name is Phocidae , derived from Latin phoca and from Greek phṓkē , they belong to the family of pinniped mammals What are the only mammals adapted to marine life! In this family there are also species such as the sea lion, the sea elephant and the sea bear.
Of this family, the seal is the only species that does not have an auditory pavilion , however, this does not mean that they do not hear (well if they do, and very well, thanks to an auditory shell that allows them to capture waves in the water and air) but have no visible ear canals like ours.
The oldest fossils of pinnipedos related to seals date from the Middle Miocene With an age of more than 15 million years! Thanks to these, it was discovered and a relationship was established between these pinniped mammals and other families of mammals such as ursidos (bears) and mustelids (raccoons, weasels, etc.).
