Not all violence is necessarily bad from the animal’s point of view.

Savage Biting = Raking nails down the back during sex.

After finally cornering the female after an exhaustive chase, the male proceeds to mount the female. Occasionally in his excitement, the ram will penetrate her anus by mistake…

Domestic sheep left alone for more than 30 years…

Extremely brutal and savage when chasing a femaleto mate with…

If the female is too exhausted to move after being raped, giant petrels will come down and disembowl her by pulling her innards out through her anus…

Passing on GenesPassing on GenesPrimal instincts: Pass on genes.

Problem: If you can’t get the girl, you can’t pass on genes.

Solution: Offer her an incentive (snacks AND virginity).

Barbed penis rips female vagina to ensure she won’t be mating again any time soon…

Why Countermeasures Why Countermeasures Don’t Don’t HappenHappen

Deaths caused by rare occurrences Deaths caused by rare occurrences such as: such as:

Skull crushings in Bison matings…

Death from nose scratching infections in otters…Biting the head instead of the neck in dogminks…

there are no genes to counter them at all.

Death from gang rapes…
