Whale Habits 10, Whale Habits

Whales are the unrivaled "opera singers" of the ocean, and their low-frequency "songs" can travel hundreds of kilometers. A new study suggests that the whale's "song" is likely a signal of male courtship.

The whale's "song" is one of the loudest in the ocean, with a frequency of about tens of hertz. It was once believed that whales used this "song" for long-distance communication. But because this "singing" is difficult to capture and locate, scientists have been unclear about its true purpose.

In the latest issue of the British journal Nature, an American team of researchers reported their findings on the "singing" of fin whales. Fin whales have different habits from gray whales or humpback whales, and they are used to living alone. The researchers used a microphone to collect the "song" of the fin whales.

Once the "singing" was captured, the researchers managed to determine the location of the "singer". When the "singer" surfaced, the researchers collected a small sample of it. The sex of the fin whale can be determined by analyzing the genetic material in it.

The researchers were surprised to find that although there were both male and female fin whales in the surveyed area, all the "singing" were male fin whales. Based on this, the researchers deduced that the fin whale's "song" was likely a courtship signal. Since fin whales are used to living alone, this "song" can attract female fin whales hundreds of kilometers away to their well-fed breeding grounds to mate with male fin whales.

Because whale "singing" frequencies are similar to those of some military or commercial sonars, some experts believe that sonar is likely to interfere with fin whale reproduction, making the already low reproduction rate of this species even more difficult.

Predation: Baleen whales mainly eat small fish and shrimp, and surprise whales mainly eat large fish and sea beasts;

Breathing: Both baleen whales and toothed whales breathe with their lungs, and the column of water exhaled by baleen whales is thin and high, making it vertical; The column of water that exhaled in surprise was sloping, thick and short;

Sleeping: Several whales float in a circle, head inward and tail outward, floating on the surface of the sea;

Whales give birth to only one whale at a time, viviparous, and juvenile whales grow up by feeding on the milk of female whales, grow rapidly, and generally live for tens to 100 years.

The living habits of whales are: hunting, breeding, sleeping, breathing.

Whales are found in all oceans of the world. It is an aquatic mammal that breathes with its lungs, and its species are divided into two categories, baleen cetaceans, toothless, baleen and two nostrils, like fin whales, blue whales, humpback whales, gray whales, etc.; Toothed cetaceans, toothed, without baleen and with one nostril, like sperm whales, narwhals, killer whales, etc. The vast majority of oxygen in the ocean and 60% of the oxygen in the atmosphere is produced by phytoplankton.

Baleen whales, on the other hand, can destroy zooplankton, the archalist of phytoplankton. In addition, toothed whales also help to maintain the ecological balance of the fish. The food of toothed whales is large mollusks that feed on fish.

Therefore, if there are no whales in the world, humanity will perish.

Summary. Dear is happy to answer for you, dear, the living habits of whales are as follows: 1. Whales do not drink seawater, on the contrary, they extract water from food by metabolizing fats.

While their specific range varies from species to species, whales live in oceans around the world. Because whales have a lot of fat in their bodies, they can easily float in the water. 2. Like dolphins, whales are believed to be descendants of land animals that have lived on land for millions of years and returned to the water about 50 million years ago.

About 50 million years ago, whales walked on land and were about the size of wolves. 3. Whales have to surface frequently to breathe, so only half of their brains are sleeping. Whale earwax shows the age of the whale, similar to the way tree rings reveal the age of a tree.

Whales are important members of the sea beasts, with a fish-like body shape, commonly known as whales. There are many species of whales, there are more than 80 species in the world, and there are more than 30 species in China's waters. They are generally divided into two categories.

There are 11 species in total, called baleen whales, which have no teeth in their mouths; The other type has teeth in the mouth and is called toothed whales, with a total of more than 70 species.
