Those who are familiar with wildlife documentaries would have seen this several times. The blowhole is located right on top of the head of the whale. This is to allow them get some air to breathe. This is the reason behind whales having to swim to surface of the water from time to time. While sharks can absorb oxygen from the water, whales cannot do the same thing.

Like other mammals, whales make use lungs to breath. They are perfect for getting the oxygen out of the water.īlue whales, do not use gills to breathe. They do this by making use of specialized structures called gills. Sharks and other fish are able to derive oxygen from water. Instead of scales, whales also have hair on their bodies. But they are not in the same category as the whale shark and other fish. This is done in an upward-downward manner.īut a blue whale is not a fish. As for the whales, they move through the water by moving their tails (called flippers). They do this movement of their tails in a lateral manner. To get around in the water, they make use of their tails and fins with which they move. They are water-dwelling in nature and have scales all over their bodies. It also means that they stretch far back in the line of evolution. This means that they have a stiff backbone. That is what happens in different countries like Japan, China, Norway and South Africa.īut by being a fish, a whale shark is a vertebrate. That means they can be caught consumed like any other fish. Make no mistake about it, sharks are fish. For weight, a whale shark can clock up to 60,000 pounds. And that is for the largest ever whale shark. Even though the whale shark is the biggest of all fish, its length is a little over 40 feet. Female blue whales are often bigger than their male counterparts. The length can reach up to one hundred feet. Apart from the sheer size, the blue whale is also very long. In fact, an adult blue whale can weigh as much as 300,000 pounds. Of all the mammals that exist, the blue whale is the largest. When it comes to comparison between whale sharks and blue whales, size is one of the most important parameters.
