Kinds of Fish

There are various kinds of fish, but they are mostly divided into freshwater and saltwater fish. Here we give you a list of different breeds of fish both in the sea water and river water. Read on...
Fish are aquatic animals and all varieties of fish are vertebrates, which means that they have backbones. They have two fins on the side of their body and their body is covered with scales. Being cold-blooded, these creatures can't tolerate extreme temperature conditions and their body temperature changes according to surrounding conditions. There are several tropical fish which only live in warm waters while others can live in ice-cold water as well.

As of today there are more than 25,000 different kinds of fish and can be categorized into three main groups - bony, cartilaginous and those without jaws. Some fish have a special sense organ which works like a radar and it is used when they travel through murky or dark waters. Here we not only give you a list of different kinds of deep ocean fish but those found in river water as well.

These were some of the pond fish types, besides other freshwater fish. Some of these are a good source of food while others are poisonous. Some of these types of fish, whether they are freshwater or saltwater fish, these can be kept in an aquarium as pets.

From the above list, you can see that there are different kinds of fish, but they can basically be divided into two categories - those living in the seas and oceans and those living in rivers, ponds, etc. Hope this gives you a pretty good idea of the different fish types found all round the world.
