Wow, impressive is an understatement here! Marty, you guys carry any defence against the big fish down there?
Why not? They're fish as they use the oxygen filtered from the water as any other fish. The main difference is the skeleton made of cartilage...but they are fish.
WHAT? Sharks, as many other fish, are ovoviviparous...that means they produce eggs retained into the body...
[h=1]Ovoviviparous[/h] Ovoviviparous animals produce eggs inside their body, but then give birth to live young. The eggs hatch out inside the mother and the offspring stay within her for a time. She later gives birth to the them. While they are within her, the young are fed on the yolk of the egg, and not directly from the mother's body. Ovoviviparity is a special type of viviparity. Some fish, amphibians and reptiles reproduce this way, for instance the sand tiger shark.
Bah, there's no such thing as a fish anyway The word "fish" is indiscriminately applied to separate classes of animals; animals with no backbones or jaws such as hagfish and lampreys, animals with bony skeletons such as eels and piranha and animals with cartilaginous skeletons such as sharks and rays. There is no biological definition of a fish, therefore fish do not exist! Doesn't stop me going fishing though... hmm, now I've confused myself. Similarly, what are those things swimming around in my fish tank?
If we put too much ovivi... ovivoviov.... offtopic into this thread, the whole rationale behind it's existance will go to bust EDIT: Did you mean finish?
