Whales are very social mammals. They are considered to be special because they are majestic and invoke a strong sense of awe in all of us.

The term 'whale' refers to some of the larger marine animals in the Cetacea order. The term 'whale' may apply to any cetacean, like porpoises and dolphins, but it is more often used for those that are longer than 10 ft (3 m). The 8.8 ft (2.7 m) dwarf sperm whales are an exception.

Whales are the heaviest live or extinct mammals, with the blue whale (Balaenoptera musculus) exceeding a record height of more than 98 ft (30 m) and 200 tons (181437 kg). The sperm whale is known to be the world's biggest toothed killer. Females of some species are bigger than males, resulting in sexual dimorphism.

Baleen whales don't have a single tooth; instead, they have baleen scales that allow them to remove water while keeping the krill they eat. The sperm whale has conical teeth, which on the other hand, are used to eating tuna or squid by whale sharks or toothed whales.

Here on our page, we have lots of amazing facts about whale evolution and lifestyle that everyone will enjoy. Let's look at these interesting facts; if you like these, then do read our fin whale and bowhead whale facts.
 

Whale Interesting Facts

What type of animal is a whale?

Whales are a type of marine mammals (warm-blooded animals that breathe air).

What class of animal does a whale belong to?

How many whales are there in the world?

Where does a whale live?

Whales live in the ocean or the sea, mostly sub-tropical ocean, and polar sea. You can find a humpback whale in the Amazon only during the wintertime. Blue whales can be found in the North Pacific and Atlantic Oceans. The false killer whale is found in tropical waters.

What is a whale's habitat?

Whales can only survive in water and prefer to remain in areas where it is colder such as the Arctic. This is why, during the winter, you'll see them along the coasts of an ocean or a sea.

They move to other areas of the ocean to maintain a sufficient body temperature. Many whale species are restricted to a certain region in the sea.

Who does the whale live with?

Most whales prefer to live in a pod. Pods refer to groups of whales that live together. Everything they do, they do together. They also indulge in hunting for prey and migration together. However, baleen whale species have been seen living alone rather than in a pod.

How long does a whale live?

Killer whales live for about 10 years, while the humpback whale's lifespan ranges from 45-50 years. Beluga whales live for 35-50 years, and blue whales live the longest, between 80-90 years. Lucky blue whales! North Pacific right whales live for 70 years, and fin whales live for around 45 years.

How do they reproduce?

During the breeding season, the males, also known as bull whales, copulate with females in a mating ritual that differs by species. Blue whales tend to achieve sexual maturity between 5-10 years of age.

To reproduce, they migrate towards breeding grounds, which are near the equator. Blue whales have a complicated mating ritual.

The male and female whales spend some time rolling about in circles before diving back into the underwater abyss. They take off and cross the surface, and males tend to thrust their penis into the vulva and ejaculate as they do so.

The embryo grows within the mother's uterus since blue whales are placental mammals. After three months of gestation, the blue whale fetus develops at a rate of 1 in (2.5 cm) per day, reaching 12 ft (4 m) by the seventh month.

After a 12-month pregnancy, the calf is born, and it swims to the surface.

The mother protects the young calf for a year, feeding it food up to 200 lb (91 kg) of milk per day. Six months are spent nursing their young newborn calves and feeding them food.

What is their conservation status?

The conservation status of these creatures varies from species to species. There are 19 species of whales like blue whales.

The following species are Endangered: blue whales, North Pacific right whales, North Atlantic right whales, and baleen whales. The Vulnerable species are sperm whales, finback whales, and gray whales. The species listed as Least Concern are humpback whales, bowhead whales, southern bottlenose whales, southern right whales, and pygmy whales.

Krill and plankton are the main sources of food for mysticetes, supplemented by crustaceans and other invertebrate food items. Blue whales have been feeding themselves entirely on krill; the minke whale eats mostly schooling fish; the sperm whale eats squid; the gray whale mainly eats bottom-dwelling invertebrates.
