Why can whales grow so big?
Why can whales grow so big?
For something like the blue whale, which could easily be 100 metric tons in body mass, they are practically doubling the size of their body because they’re engulfing a volume of water and Krill that’s larger than their own body.
Why have whales evolved to be so much larger than the largest land animals?
The emergence of concentrated prey, and the evolution of a technique for capturing them, allowed whales to smash through the diet-imposed ceiling that keeps other marine mammals big, but not too big. That’s why they, rather than manatees or seals, transformed from big animals into the biggest animals that ever existed.
Why some whales become giants and others are only big?
Being large has helped whales exploit such food bonanzas in a few ways. Bigger creatures can travel farther using less energy per unit of mass. So big whales can cross wide swaths of barren ocean to reach food-rich upwellings.
Did whales used to be bigger?
Most giant cetaceans only got giant in the past 4.5 million years, suggesting they could have room to grow. We live in an age of giants. Today’s enormous whales are the result of a relatively recent evolutionary growth spurt.
What is the longest whale?

Is Panda the cutest animal?
The giant panda is a firm favourite when we are talking about cute animals, but there is much more to these bears than meets their black-patched eyes. Despite its name the giant panda is unrelated to the red panda. It is the rarest of the 8 species of bear, living in only a few mountain ranges in central China.
What makes pandas so cute?
They remind us of babies especially with their big eyes (the eyes are not that particularly big but the black patches around their eyes make them appear larger) round faces, snub noses and large heads (a large head and tiny body is much cuter than a tiny head and large body (like rats).
Are pandas really lazy?
A new study published by Science (“Exceptionally low daily energy expenditure in the bamboo-eating giant panda”) shines some light on the panda lifestyle. Giant pandas have the digestive system of a carnivore, yet the feeding habits of an herbivore. Yet even for herbivores, they are exceptionally lazy.
Why do pandas eat slow?
The panda’s diet requires it. Though its digestive system is built for a carnivore, the giant panda survives almost exclusively on bamboo, making digestion an inefficient process. Because this diet provides so few nutrients, pandas need to slow things down.
