Drawing a clear line between Sharks And Whales can get confusing. Learn which is a mammal and which is a fish.
A Whale Shark: Despite being called a Whale Shark and sharing several traits with whales, this creature is a fish not a mammal.
If you are anything like most people, you would have at some point thought sharks and whales, especially the very large species, are similar or even related.
Take the example of the largest sharks and whales, for instance.
The whale shark and the basking shark are filter feeders, so are the grey whales, blue whales, and so on. They are
There’s a very popular story about a whale swallowing a person. But based on science, can a whale swallow a human being?

If you’re anything like many ocean goers, you may have wondered what it would feel like for a whale to swallow you. Especially if you’ve ever seen one of these absolutely massive creatures in real life.
You’d probably think being swallowed by a whale would be one of the most horrible things that could ever
Despite being one of the largest whales alive today, the Fin Whale is also one of the fastest cetaceans in the Earth’s waters.

The Fin Whale or finback whale is a baleen whale and the second largest creature on Earth; second only to the Blue Whale.
This remarkable creature is unique in a number of ways. For one thing they produce the lowest frequency vocalization of any whale. They produce sounds as loud as 188 decibels but the frequency is so low that humans can’t hear it.
In addition, though so large, this whale is sleek and built for speed. American naturalist Roy Chapman Andrews
The debate about underwater sonar and whales has been on for years now. Here are the facts.
The debate about whether underwater sonar is harmful to marine life or not, especially cetaceans, has been raging for long now.
Active sonar (sound navigation and ranging), is the transmission equipment used on ships to assist with navigation. But this becomes a problem for some categories of marine animals for example whales and dolphins. That’s because these creatures use echolocation, or bio-sonar systems, to locate predators and prey.
It appears that active sonar transmitters can confuse these animals and even interferes with some of their basic
The Gray Whale resisted capture so much that whalers named it “Devilfish.”

The Gray Whale is a medium-sized baleen whale and the only surviving member of its genus and family. This species is a migratory animal that travels annually between its feeding and breeding grounds.
These whales have a hump and a ridge of sharp bumps running down their backs rather than a dorsal fin. They also prefer to stay close to shore – feeding in shallow waters.
The common name, Gray Whale, comes from the contrasting gray patches and white mottling on its dark colored skin. The white patches are the result of barnacles and lice that have attached themselves to the whales’ skins. In
One sea creature that has suffered extreme exploitation is the whale. Here’s the current status of some well-known whale species.

Whales are magnificent, extremely large, and generally gentle sea mammals. Different species of whales have lived in the Earths’ waters for millions of years now but they are now threatened due to excessive whaling and uneven climatic changes.
Specifically, unregulated and relentless hunting in past centuries led to a sharp decrease in the population of most species of whales.
In fact, in some of the more severe cases, the current population is just a mere fraction of the pre-whaling population.
Initially, commercial whalers were monitored by the International Whaling Commission (IWC).
However by 1986, due to the extreme depletion in the number of these creatures the IWC temporally banned whaling entirely.
