What mammals are monogamous ?

Answer 1

humans only sometimes are ;)

http://www.trinity.edu/rnadeau/FYS/Barash%20on%20monogamy.htm Of about 4,000 mammalian species, only a handful have ever been called monogamous. The tiny list includes beavers and a couple of other rodents, otters, bats, certain foxes, a few hoofed mammals, and some primates -- notably gibbons and the tamarins and marmosets of the tropical New World.

http://www.students.emory.edu/HYBRIDVIGOR/issue1/mating.htm
among primates, there are only two monkeys--the marmoset and its South American cousin, the tamarin--that are genetically monogamous. All other primates--monkeys, apes, and humans--often mate outside their socially monogamous partnerships

wikipedia
Monogamy is one of several mating systems observed in animals. The amount of social monogamy in animals varies across taxa, with over 90 percent of birds engaging in social monogamy but only 3 percent of mammals engaging in social monogamy. The amount of sexual monogamy appears quite rare in the animal kingdom. It is becoming clear that even animals that are socially monogamous engage in extra-pair copulations.

What Mammals Are Monogamous

Answer 3

None that I can think of. Multiple partners makes more sense from a natural selection point of view. Males can spread their genes as far and wide as possible; females select what they perceive as the best possible mate(s) from those available at the time, which might vary from breeding season to season.

Answer 4

I would guess that none are.
Some, like beavers, seem to be a good choice for argument though...

Humans sure are not, neither are the other apes. Whales are not either.

Answer 5

Nope - some, not most. Not necessarily heterosexual, either.

Sorry, misread. I think martens and beavers are. Maybe muskrats. Possibly pikas. Probably others about which I am not aware.

Answer 6

I think whales are.
