Re: Do marine mammals have menstruation cycles that result in bleeding?

Hi Daniel,

That's an interesting question.  I did a Google search for "whale" and
"menstruation" and found an answer at www.whales-online.net.  The excerpt
and link are below:

Hfaiedh  	12/04/2003
If a female whale is not impregnated during mating season, will there be
menstruation?
Our answer
	No, whales do not have menstruation; there is no loss of blood as there is
with other species of mammals.

I don't know if this is true for other marine mammals as well, but it seems
reasonable to think so.

Hope this helps!
