Adult blue whales are very beautiful, with a soft blue back, wrinkled abdomen and an ochre film like diatom. Dark brown eyes are small but friendly, shining with blue luster, giving the blue whale a reasonable expression. Once upon a time, in order to breathe, a bunch of turquoise backs surfaced one after another, forming a beautiful scenery on the ocean.
The life of the blue whale is full of mystery. People think that the blue whale's family can last a lifetime, and husband and wife can live in harmony. They constantly exchange different signals and always act in concert.
When the blue whale family has offspring, parents carefully feed their only child until the calf is old enough to swim alone or with one or two whales of the same age.
Whale milk is a very good nutrient. The young whales eating this high-calorie food grow rapidly, gaining 75 grams per minute and 100 kg day and night. The nipple is hidden in the special breeding bag of the mother whale and can hardly be seen outside. When the calf lets the mother know that she is hungry, the mother will stretch out her nipple to feed the calf. The calf will be weaned at the age of seven months, and then the nursing bag with nipple will not open. Hungry young whales have to imitate their parents, open their mouths wider and fill their stomachs with small creatures floating in the water as much as possible. The blue whale belongs to the warm whale family and is named after the striped wrinkled skin on the abdomen. Warming whales belong to the suborder baleen whales. They are called baleen whales not because they have sparse and slender beards on their mouths, but because they have soft and elastic beards on their maxilla, which hang down from their jaws, so they are called baleen whales. The blue whale has about three baleen whales. Because of this whisker, the half-open mouth of the blue whale is like a sieve, which helps the whale to separate water from food.
Blue whales have a good appetite. In order to eat, adult blue whales can't live without two tons of small creatures in their bellies. Giant whales feed on the ocean. If cetaceans (green and blue whales, Pacific whales and Japanese Pacific whales) swim with their wide and big mouths open when eating, as if casting nets on the ocean, then baleen whales, blue whales, great fin whales, fin whales and humpback whales hunt in groups and never ask their neighbors for help.
When a whale preys in the ocean, its small eyes are so high that it can't even see the prey under its nose. This is the real whalebone, which indicates that it satisfies the panic on the Antarctic scale. These short hairs are only 1 cm long and grow in three rows along the maxillary edge of the head. Warm cetaceans have only 50 to 100 scattered hairs on their bodies. When the heads of these animals hit the scales, countless shrimps were in a mess in the baleen, and then the whales knew it was time to open their mouths.
The method of domestic warm whales preying is like waving a net: whales swim slowly and calmly on the ocean surface, but as soon as they meet scales, they immediately open their mouths and swim forward quickly, and the prey falls into the net. The whale took a sip of water, filtered it out first, and then swallowed all the edible things blocked by the "filter". The net on the "filter net" is very small, which can not only stop small fish and squid, but also shrimp with a size of several millimeters. These shrimps are the staple food of whales. In summer, whales must store a lot of fat so that they can survive for months or even half a year without food.
