True that sharks are the only water creature that doesn't lay eggs, thus the young are still born. Because it's warm blooded?

Some sharks lay eggs, this is called oviparity. In most of these species, the developing embryo is protected by an egg case with the consistency of leather. Sometimes these cases are corkscrewed into crevices for protection. The mermaid's purse, which can wash up on shore, is an empty egg case. Oviparous sharks include the horn shark, catshark, Port Jackson shark, and swellshark. http://en.wikipedia.org/wiki/Shark Nov 06 09, 1:36 AM

Not all sharks are viviparous, some lay eggs as well. All sharks are cold-blooded, so being warm-blooded as a reason for vivipary is not correct. http://www.sharkinfo.ch/SI1_00e/vivipary.html Nov 06 09, 3:04 AM
