Monogamy is indeed extremely rare in mammals, and is unknown in
cetaceans, although given what we know about many breeding systems (=
little) who knows what's out there; recent molecular work on paternity
has turned up somne surprises in other taxa.
 
The type of breeding system is strongly correlated with ecological
effectors.  Monogamy generally occurs only where parental care is
important.  For an outstanding review, read Tim Clutton-Brock's paper
"Mammalian mating systems" (Proc Royal Society Lon. B 236: 339-372, 1989).
 
Also, Brownell and Ralls wrote a review of the potential for sperm
competition among whales (Rep int Whal Commn, Special issue 8: 97-112,
1986).  By the way, right whales have the largest testes in the animal
kingdom, one ton the pair!
