Is anyone familiar with the Stellar's Sea Cow?  I found a reference to
it under dugong.  The dugong is similar to a manatee, but it has a while-
like tail, wheras the manatee has a paddle-shaped tail.
What shape tail did the Stellar's Sea Cow have?  Where did it live?  How
did it go extinct?
Does this group of mammals have a fossil record?  Were there giant species
alive in the Pleistocene?
What are these guys related to?  I suspect NOT the seals.
OB cp:  These animals are probably formidable pests on cp populations,
particularly Utricularia.  Fortunately I have never had a manatee
infestation in my aquatic Utricularia pails.
