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. http://www.whales-online.net/eng/FSC.html?sct=forum&pag=msglst.asp I don't know if this is true for other marine mammals as well, but it seems reasonable to think so. Hope this helps! Joy
