You'd be very hard pushed to find an animal that behaves in that way, so don't insult them (i.e. animals) like that.
Romanticising nature much?
dolphins gang rape females to death
ducks gang rape females to death
bears rape female
snakes gang rape females
baboons maul females to prevent them mating with other males
sea otters rape baby seals to death
dog's penises are designed to tear the female if she attempts to leave copulation
And don't get started on the invertebrates...
