Now you might think why I am going to cover a little about SHARKS?.

I thought it might be helpful for some of you and to your children as well. My son really love sharks so much to the extend that he thought that he is a shark. He even played as a shark and sometimes bit me.. ha-ha. He was so amaze about the characteristic of a shark and he loves most especially the powerful jaw of a shark by the time he handle his prey.

He always carries with him his toy shark wherever we go and played with it.

And that is why I decided to write an article about sharks…

Let’s get started…

What is a shark?

Sharks are a group of fish characterized by a cartilaginous skeleton. Meaning its skeleton is made of cartilage. Cartilage is a flexible tissue that found in many areas in our body.

Sharks has five to seven gills on the side of their head, they are the sister group of “rays”. They existed for more than 420 million years ago. The first discovered evidence of the existence of a shark was their scales way back million years ago.

There are 470 known shark species as of today. Most sharks can be seen 2,000 meters down depth on the ocean. Most shark do not live on freshwater but there are few species live on both seawater and freshwater. Bull sharks and river shark are the group that can live in both seawater and freshwater. Most sharks also have to keep moving in order to breathe.
