Do whales need to breathe? How often do they breathe?

How often whales breathe is related to the way they dive. Whales can dive shallowly, where they usually take a breath every 12-20 seconds. After 10-20 shallow dives, they dive deep. At this point, they typically change air every 8-50 minutes. How often a whale breathes depends on the species. Some varieties need a breath after 10 minutes of diving, some varieties can last about 30 minutes, and some varieties can last 50 minutes.

1. Do whales need to breathe

? Whales are very large animals that live in the ocean. They belong to the class Mammalia, which is classified as mammals. Therefore, many characteristics of whales are also in line with the characteristics of mammals, including breathing patterns and respiratory organs. Mammals have lungs, a relatively advanced structure, and breathe with lungs, which has a relatively high respiratory efficiency. Whales do the same thing. They breathe with their lungs. The whale's lungs are also relatively developed, with one lobe on the left and one on the right, and rich in capillaries, which have the ability to transport oxygen.

Because whales breathe with their lungs, they can't breathe normally in the water. They can only breathe when they touch the air on the surface of the water. This causes whales to breathe above the surface of the water after diving for a period of time. They can't stay in the water all the time. However, because whales have more developed lungs, they can breathe for a longer time. But even if they persist for a long time, they will always come out of the water.

2. How often do whales breathe? As mentioned

above, whales need to breathe out of the water because they breathe with their lungs and can't breathe normally in the water. The specific time of whale breathing is related to many factors. Whale diving is divided into shallow diving and deep diving, and the breathing time of whales during these two kinds of diving is also different. Whales breathe more frequently during shallow dives, generally every 12-20 seconds. But if deep diving, then the breathing time is longer, generally between 8-50 minutes. Whales dive shallow more often, and then dive deep after 10-20 times.

In addition, the breathing time of whales is also related to species, and different whales can dive for different times. Whales with shorter persistence time can persist for about 20 minutes, while whales with longer persistence time can persist for about half an hour, and more can persist for about 50 minutes. For example, the blue whale is a relatively common whale, which can last 10-30 minutes in deep diving.
