A group of wild octopuses have been found, which were engaged in a kinky and violent society of jealous murders, strategy of gender-deception and once-in-a-lifetime sex.

A group of researchers from the University of California, Berkeley journeyed to Indonesia to find that wild octopuses are the opposite of the shy, unromantic loners their captive brethren appear to be.
The researchers watched the Abdopus aculeatus octopus, which are the size of an orange, for several weeks.
The male octopuses were behaved as picky and macho, carefully select their mate. They then guarded their newly mate so jealously, that they would occasionally use their 20-to-25-cm tentacles to strangle a romantic rival to death.

Also a form of travesty has been observed: a smaller “sneaker” male octopuses showed their feminine side by swimming girlishly near the bottom and keeping their male brown stripes hidden in order to win unsuspecting conquests.
About a month after conception, the female gives birth and both the mother and father die. This is not caused by the sex, but because the octopuses only produce offspring once during a very short lifespan of a year.
