In the marine world, there are a variety of huge creatures, such as blue whales, humpback whales, sperm whales, king squid, etc., which are much larger than the elephants on land. Recently, when the domestic scientific research team inspected a certain sea area in the South China Sea, it found a variety of whales, among which the sperm whale group was found again, or a pair of sperm whale mother and son, and the interaction scene between sperm whale mother and child was very warm.
According to the investigators, this is the second consecutive time that researchers have found sperm whale groups in a certain area of the South China Sea, and since last year, they have witnessed and recorded the species in the South China Sea again, which also reflects the increasing ecology of the South China Sea on the other hand, attracting more and more whale groups.
In the animal world, sperm whales are fish-like, breathe with their lungs, are a kind of mammal, and are also the mammals that dive the deepest and have the longest dive, diving up to 2200 meters underwater, and can stay underwater for two hours, and their swimming speed is very fast, up to a dozen nautical miles per hour.
Sperm whales are very conscientious to juvenile sperm whales, and due to the slow reproduction rate of sperm whales, females do not mature until they are 9 years old, while males mature longer. Adult females are pregnant only once every 4-6 years, one baby whale per litter, rarely twins, and their lactation period is as long as two years, during which time the mother sperm whale carries the baby sperm whale to move together, and take care of the sperm whale safety and so on.
It is relatively rare to find sperm whale groups on the surface of the sea again, this is due to the long diving time of sperm whales, and the chance of seeing them on the sea surface is not large, but because sperm whales are mammals and must breathe, so every once in a while, sperm whales will surface on the surface of the sea, spew out the exhaust gas in its body, and breathe and store fresh air, so that they can dive deep into the seabed again to find food.
Sperm whale is the largest toothed whale, up to 18 meters long, weighing more than 50 tons, widely distributed in the world's non-icy waters, from the equator to the poles of the non-icing sea can be found in their tracks, but due to human overfishing, coupled with marine pollution, sperm whales in the Red List of Threatened Species listed as vulnerable species, need to be concerned and protected.
