Blue Whale

The blue whale is a marine mammal and is found in all seas except the Arctic Ocean. Although their average lifespan is 80 years, they are at risk of extinction due to hunting by humans and have been protected. Their main enemies in nature are killer whales, and they mostly target cubs. Blue whales feed on different types of krill, depending on the ocean in which they live. It can be said that krill is almost the only food. They migrate seasonally for different reasons, such as more food sources and reproduction. Their average swimming speed is 20 km/h, but they can raise these speeds quite a lot if they need to.

Blue whales, also known as sky whales, can be 33 meters tall and weigh 150 tons. The fact that the blue whale was not in one piece during the measurement of these values may indicate that it may be even heavier than measured. On average, blue whales become pregnant once every 2-3 years, and their gestation period is around 1 year. Blue whales are toothless and their throats are quite small compared to their size. For this reason, they do not have the ability to break down and swallow large nutrients that they take into their mouths. It is still more mysterious for what purpose they make the sounds they make, and these sounds resemble songs. Blue whales mostly swim on and near the surface. They usually dive to feed, and this dive time is on average about 10 minutes. The longest recorded dive times are 36 minutes.

Blue whales are the loudest animal in the world after sperm whales.

The dorsal fins are quite small in size and are most often visible when diving.
