Sorry if this isn't the best place for this posting...

What is a monotreme?  An article on the echidna in the Feb., 1991
Scientific American says that the echidna has "a cavity uncommon in
mammals, into which all the internal organs empty...".  Now, this
is obviously wrong (because the heart doesn't empty into this
cavity, nor do the lungs, etc.) so I presume that this single
cavity gets the urine and sperm and feces.  Is this correct?

Please E-mail replies.

Thanks.
