Aquatic life is very vast as oceans have a lot of organisms and vegetation. Many unexplored regions may contain unidentified animals as well.

Although, whales and sharks are some of the parts of aquatic animals that are considered dangerous. While whales and sharks are very different from each other, but people tend to take them as similar aquatic animals. 

Key Takeaways

What is Whale?

Many aquatic animals are there in the ocean, sea, etc. One of them is whales. Whales are considered mammals, a different class of vertebrates. Whales have smooth skin, no scales, and use tails for swimming. 

As for reproductions, whales give birth to young ones. And they are warm-blooded animals. As for the characterization, whales have bones. Unlike sharks, it has lungs to respirate.

Whales have to come up to the surface to get oxygen as they cannot retrieve oxygen from water and has lungs to breathe. Most importantly, the air is taken in by the airhole on the top of the whale’s head. 

They are warm-blooded animals, therefore they can regulate temperature as a result they can feel the temperature of their surrounding.

Whales give birth to the young ones, that’s why they don’t let their babies go away. Apparently, they provide required attention to the baby whale. Also, they feed them milk. 

Moreover, whales are much friendlier to human beings and don’t have hunting tendencies. And they feed on plankton and krill as well as on small fishes and squid.

Additionally, they create sounds to communicate with each other. Also, they weigh more than 100 tons and their maximum height is 35 meters.

What is Shark?

Many aquatic animals can be found in the ocean, sea, and other bodies of water. One of them is sharks. Sharks are considered fishes, a type of vertebrate. Sharks have scales and use a streamlined body along with tails for swimming.

As for reproductions, sharks lay eggs. And they are cold-blooded animals. As for the characterization, whales have no bones but cartilage. Unlike whales, it has gills to respirate.

Sharks respirate through gills absorb dissolved oxygen in the water. As the slits on the side of the shark’s head consist of the gills. 

They are cold-blooded animals, therefore they are unable to regulate temperature as a result they can’t feel the temperature of the surrounding.

One of the reasons why sharks stay in temperate or tropical waters. However, some cold sharks live in polar environments.  

The sharks lay eggs, but some lay young ones as well. The young ones receive little or almost negligible paternal care. Although, the quantity of the eggs is very few. 

Moreover, sharks are considered dangerous and have hunting tendencies. And they feed small fishes and all marine animals. Additionally, they do not create sounds to communicate with each other.

Also, they weigh just a little over 2 tons and their maximum height is six meters.
