Why are blue whales the largest animal on earth?
Blue whales are the largest animals ever known to have lived on Earth. ... The results demonstrated that the availability of their prey limits that body size in all whales, but only filter-feeding whales have evolved a feeding strategy that helps them to achieve the largest body sizes to have ever evolved on Earth.
Is the blue whale The largest creature on Earth?
The Antarctic blue whale (Balaenoptera musculus ssp. Intermedia) is the biggest animal on the planet, weighing up to 400,000 pounds (approximately 33 elephants) and reaching up to 98 feet in length. A blue whale fluking, or preparing to dive, off the coast of Marissa, Sri Lanka. ...
Why can whales grow larger than the dinosaurs ever did?
After looking at fossil data in ocean sediments, the scientists ultimately concluded that whales expanded in size as a response to a change in the way their food supply was distributed in the ocean.
Why do blue whales grow so large?
Stronger upwelling created the right conditions for baleen whale prey, such as krill and forage fish, to become concentrated in dense patches along coastlines. Whales that fed on these prey resources could forage efficiently and predictably, allowing them to grow larger.
Why are whales mammals?
Whales are mammals which means that, like humans and other land mammals, they have three inner ear bones and hair, they breathe air, and the females produce milk through mammary glands and suckle their young.
Who is big megalodon or blue whale?
Megalodon vs.
When it comes to size, the blue whale dwarfs even the largest megalodon estimates. It's believed blue whales can reach a maximum length of 110 feet (34 meters) and weigh up to 200 tons (400,000 pounds!). That's more than twice the size of even the largest megalodon size estimates.
Are blue whales bigger than dinosaurs?
Far bigger than any dinosaur, the blue whale is the largest known animal to have ever lived. An adult blue whale can grow to a massive 30m long and weigh more than 180,000kg - that's about the same as 40 elephants, 30 Tyrannosaurus Rex or 2,670 average-sized men.
What is the longest creature on Earth?
A deep-sea expedition led by the Schmidt Ocean Institute has discovered 30 potentially new species of marine creatures, including a siphonophore that's thought to be the longest animal ever observed. It has been estimated to be 46 metres long, nearly six times the length of a Routemaster double-decker bus.
Do blue whales still exist?
Blue whales are still an endangered species and there are thought to be no more than 25,000 living in the world today.
Are blue whales friendly?
The blue whale is the largest animal to ever live, in the entire history of Earth. ... Interestingly, though they are enormous, blue whales are not predatory. They filter feed for tiny krill and are totally harmless to people (other than through accidental collisions).
Is a blue whale's heart?
A blue whale's heart is the biggest on the planet, weighing 400 pounds. That's the weight of about 35 gallon paint cans. A blue whale's heart is only 1% of its body weight - however the whale's immense weight is supported by water. ... When the whale came to the surface to breathe, its heart raced to 25-37 beats a minute.
Why whale is so big?
We now understand that whale gigantism is tied closely to two things: one, their choice of prey, and two, the coincidence of their evolution with a global increase in the upwelling of nutrient-rich water from the depths of the ocean.
Why are whales larger than elephants?
Whales also live in an environment that supports their large size. There is a lot of room in the ocean and also whales don't have to fight gravity like large land animals (think of an elephant the size of a whale!!)
Why do whales exist?
Both hippos and whales evolved from four-legged, even-toed, hoofed (ungulate) ancestors that lived on land about 50 million years ago. ... Unlike the hippo's ancestor, whale ancestors moved to the sea and evolved into swimming creatures over a period of about 8 million years.
