When is the International Seal Day every year?

Seals are a very interesting animal. From birth, they keep pace with the whole group. You would never think that baby seals were born at the same time. In order to protect seals, there is an international seal day every year. In this traditional festival, Bian Xiao takes you to know which day is International Seal Day? And a seal is introduced.

The purpose of establishing International Seal Day is to protect the development and reproduction of this rare animal, seals, and also to protect the ecological balance.

In order to protect seals, a rare animal, the Save the Seals Foundation decides that March 1 day is the International Seal Day every year.

Seals are the general name of the family of pteropods seals. The sealing body is thick, round and spindle-shaped. The whole body is covered with short hair, the back is blue-gray, and the abdomen is milky yellow with blue-black spots. The head is nearly round, the eyes are big and round, there is no outer auricle, the kiss is short and wide, and the upper lip tentacles are long and thick, and they are like beads. All limbs have five toes, and the toes are webbed, forming flippers with pointed claws. The hind flippers are large, extending backward, and the tail is short and flat. Coat color changes with age: the coat color of young animals is darker, while that of adult animals is lighter.

They are very similar to humans in many places. For example, seals have almost the same body temperature as humans.

On Prince Edward Island in northern Canada, take a helicopter from Charlestown to Newfoundland near the North Pole to see seals. Every March, in just two weeks, all the female seals in the world give birth to their babies at the same time.

Seals are large mammals and marine animals. They live for about 30 years, mature at the age of 4 or 5, and are in heat every spring. Their mating takes place in the depths of the ocean, so little is known about it at present. At present, only one photo of a leopard mating in water has been taken in the world.

Seals are not monogamous. Every year, the male seal marries a new wife. Like some men, male seals have no responsibility to raise their children except to impregnate their females. It is entirely up to the mother seal to breastfeed and raise the baby seal alone. Interestingly, after each pair of seals mate, the sperm does not immediately combine with the egg, but hangs on the uterine wall until two or three months after implantation. In this way, under the command of a mysterious "signal", they will start the formation and development of embryos on the same day in June every year.

After pregnancy, they went to the North Pole with the male seal, returned here with ice eight months later, climbed onto the ice and gave birth to the baby seal. When a male hooded seal swims, he will blow out a red bubble as big as his head, just like a child who is good at blowing bubble gum. For a while, he would blow up the bubbles and swallow them in his mouth. The female seal was chased by this red bubble. The baby seal born by hooded seal is the most beautiful. They are also called blue-backed seals.

It has blue fur as smooth as brocade. Regarded as a treasure in the sea by human beings. In early spring and February, huge ice cubes are still floating in Newfoundland waters, and thousands of seals from Qian Qian come here like a group army expedition to carry out the greatest annual life extension of the seal kingdom. Naively dragging the pregnant fat mother seal, she twisted out of the crack in the ice, climbed onto the ice, and kept turning around to prepare for labor.

There are many kinds of seals, the biggest two are harp seals and hooded seals. Mother seal's milk contains a lot of oil and nutrition. The baby seal needs to eat milk 10 times a day, and grows 2.5 kilograms a day. /kloc-after 0/2 days, it grows to 38 kg. After changing the fetal hair, mother no longer cares about it, nor teaches it to swim, and walks alone. It goes to find a new lover. A female seal gives birth to at least 20 children in her life. When the ice gradually melts and baby seals fall into the water, they don't catch fish immediately. Before they master survival skills, the fat in their stomachs can help them last for six weeks.

In order to adapt to the cold environment, seals have accumulated thick fat. These fats enable them to keep their body temperature at 36-37 degrees Celsius like humans.
