The Innumerable Underwater Species

We all know that earth is covered with about 70% of water. And oceans and seas are 97% of all the water. There are a vast number of species under these waters, which we couldn’t yet explore to full extent.

There is a big project going on to find all the oceanic species. This is a big one because it is not that easy to explore the deep oceans. It is almost like counting stars of a galaxy. According to the studies, there are around 230,000 sea species discovered so far. And scientists say that they might be able to discover a million more species by 2010.

The main disadvantage for us not yet discovering many species underwater is that we can’t help them from getting extinct. There are many species underneath oceans which have become extinct even before we got to know them.

The main cause of their extinct is due to climatic changes which is nothing but because of our increased pollution.

Piranhas are more savage than sharks

The most savage thing after sharks is the piranha. Though small in size, it is very dangerous fish, and more savage than a shark, I must say.

Piranhas are named for ferociousness. But the name for them has come from Portuguese terms of piro which means fish and sainha which means tooth. Piranhas possess small teeth enough to fit their size, but these teeth are the main weapons of these fish. These are razor sharp, with an interlocking pattern, fitted to a strong jaw. This makes them easy to devour their food including the strongest bone. Their teeth help them only to tear down their meal; hence they cannot chew their food. Thus when they bite big pieces of flesh they just gulp them down. Piranhas are very greedy thus devouring at their meal very fast.

Piranhas move only in groups. This is what makes them more savage. A group of piranhas can drag some big animal on shore into the water. While piranhas are dangerous, hungry piranhas are more savage. They also rely on dead bodies in water.
