A description of the blue as earth largest animal

Blue whales are rorqual whales, a family of baleen whales with pleated throat grooves that expand when the animal takes in water while feeding. The amount of krill a blue whale captures in one gulp of water may provide nearly half a million calories of energy.

They gain pounds a day! What scientists do know, however, is that mother blue whales usually give birth to single calves, which are 20 to 23 feet 6 to 7 m long, and weigh up to 6, lbs. They seek warmer equatorial waters before embarking on an elaborate mating ritual that involves the male and female rolling over one another, diving in a deep dive, then suddenly swimming to the surface for copulating.

The calf is born tail first at 12 months and weighs about 2,kg, swimming immediately to the surface for air. The giant animals feed by first gulping an enormous mouthful of water, expanding the pleated skin on their throat and belly to take it in.

How much does a blue whale weigh? Probably the most spectacular thing about blue whales that's bigger than big is the sounds they make.

Blue whale length

When it surfaces, it exhales air out of a blowhole in a cloud of pressurized vapour that rises vertically above the water for up to 9m. Deep breath! Their future is unclear While commercial whaling is no longer a threat, recovery has been slow and new threats plague blue whales, like ship strikes and the impact of climate change. Unlike toothed whales, blue whales lack teeth and instead have baleen, which are thin, semirigid plates that grow down from the top of the whale's mouth. The males have the biggest penis in the animal kingdom, about 30cm in diameter when erect and 3m in length. Balaenoptera musculus, the blue whale, is the largest animal ever known to have lived on the planet — larger than dinosaurs, and movie monsters aside. What do blue whales eat? The whales migrate long distances to find food in cold waters and rear calves in warmer areas during the coldest few months of the year. Blue whales exchange between 80 and 90 per cent of oxygen in their lungs each time they breathe, compared to just 10 or 15 per cent in humans. They gain pounds a day! Their hearts, as much as an automobile. What Do they Sound Like? One of the most important reasons that whales have become so large is they have more space - more room to roam.

We have come to feel that wiping any species of animal off the face of the earth forever is an evil thing for humans to do.
