Why do whales eat small things?
This means that, although larger toothed whales can dive deeper, their prey/dive ratio is smaller than that of smaller whales. One of the main constraints to eating, for baleen whales, is to open their mouths wide enough to swallow massive amounts of krill-containing water.
Why are blue whales important?
Whales are an important part of the marine food chain and play a huge role in maintaining the health of our oceans. Their iron-rich poo is a really important source of nutrients in the marine food chain, promoting Southern Ocean productivity, which boosts fishery yields.
Are whale sharks fish?
The whale shark is the biggest fish and shark in the world. These gentle marine giants roam the oceans around the globe, generally alone. However, large numbers of whale sharks often gather in areas with abundant plankton food—making them prime tourist attractions.
Why whale is not fish?

Fish are cold-blooded, so their body temperature changes depending on the temperature of their environment. Fish lay eggs, which must still grow into a baby fish.

What would happen without whales?
Were it not for whaling, the animals might have removed 2 million tons of carbon from Earth’s atmosphere. In other words, sperm whales fight climate change without trying. So if the whale population dwindled to zero, that would result in boatloads more carbon remaining in the atmosphere.
What happens if blue whales go extinct?
Whales and The Environment For example, a blue whale can consume as much as 40 million krill per day, so you can imagine its impact on stabilizing the aquatic ecosystem if the blue whale species were to become extinct. When one animal species important to the food chain dies, it allows other species to thrive.
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.
