4 species, around 20,000,000
there are more then 25 species of piranhas
I think it's about 1000000000 piranhas
2,596,000
No more than 100, if that many at present.
there are no more than 1000 leopard sharks left in the world
Depending on the species of shark and the number of piranhas, supposedly piranhas could be more dangerous. What makes piranhas so dangerous is the fact that they swim in schools of 100 strong. Even so, both animals are misunderstood because of movies like Jaws and Piranhas. Both animals should be treated with respect.
there are 1,000 - 2,000 pandas left.
there are only about a million giant clams left in this world
There are more than billion names of Waleed in the world!
both can be as dangerous as they attack when they smell blood in the water. However as piranhas hunt in groups of up to 20 i believe piranhas are more dangerous.
they are far more common than you may think
Enough for many more bowls of Asian Tortoise soup.
