Blue whale what does it look like

When eating, the whale lets a huge volume of water and krill into its mouth. It then pushes the water through its baleen plates , which trap the tasty grub to be swallowed. Their calls are the loudest of any creature on the planet , in fact, and can be heard underwater for hundreds of kilometres. During the feeding season, they fill up on krill in cold polar waters. They then travel to warmer, tropical waters to mate and give birth.

Now that they are a protected species, the main threats to blue whales are ship strikes by large boats. It would be quite difficult to build a tank large enough for such a huge whale so… no it does not make a good pet. Because of its immense size, this whale species has never been kept in human care. If they were kept in aquariums, they would require extremely intensive care. These whales spend their summers in the cooler waters of the Arctic or Antarctic oceans, and their winters in the tropical waters near the equator.

The older whales, and pregnant whales, begin their migration first. Groups generally migrate according to age, and sex, with the youngest animals migrating last. During the migration ,they eat virtually nothing, and survive on their fat stores.

Once the whales reach tropical waters, they give birth and breed. These whales has a calf every years, and carries the baby for about 1 year.

After a year-long gestation, the whale gives birth to a baby called a calf, which is about 23 feet long at birth, and weighs between 5, and 6, pounds. Size relative to a bus:. Least Concern Extinct.
