How do whales mate and reproduce?

At the mention of whales, everyone is surely familiar with them; they are the largest type of fish in our country, and also very fierce, rarely seen, so how do whales mate and reproduce?

1. How do whales mate and reproduce?

From late July to early August, male whales will circle around a female for several weeks before the pairing ends. Generally, if a second male approaches the female, the three will compete on the water surface and make a sound to court the female. Whale mating is very brief; the gestation period is 11 and a half months, and they mostly give birth in winter, one calf per birth, with the newborn calf about 5 m long. The nursing period is 6-7 months, and the lifespan is about 50 years.

2. How many kinds of whales are there?

Whales fall into two major categories: one is baleen whales, which have no teeth; the other is toothed whales, which have sharp teeth. There are also smaller categories, including the blue whale, humpback whale, killer whale, beluga, and others. Baleen whales worldwide have 3 families, including the right whale family, the gray whale family, and the fin whale family, with about 6 genera and 11 species in total. Toothed whales worldwide have 8 families, including the porpoise family, the sperm whale family, the beaked whale family, the narwhal family, the dolphin family, the porpoise family, the dolphin family, and the pilot whale family, with about 34 genera and 72 species.

Among them, the largest whale in the world is the blue whale, a marine mammal belonging to the suborder Mysticeti. There are four subspecies in total. The blue whale is considered the largest animal known to have ever lived on Earth, reaching up to 33 m in length and 181 tons in weight. The blue whale has a slender body, and its back is grayish-blue, though in the water it sometimes appears lighter in color.

Next, the loneliest whale in the world is called Alice. She was discovered in 1989 and has been tracked and recorded since 1992. In the eyes of other whales, Alice is like a mute. For so many years she has had no relatives or friends; when she sings, no one hears her, and when she is sad, no one pays attention. The reason is that this lonely whale's frequency is 52 hertz, while normal whales' frequency is only 15-25 hertz; her frequency has always been different.
