Distant Relationships

Octopuses are strange and fascinating creatures,in addition to being smart enough to open jars and manipulate a Rubik's cube,they also have other varied and unique traits. They are very antisocial and live alone in spaces they seemingly melt into. Their bodies are squishy except for their brain sac which is about the same size as their eye, allowing them to funnel into their tiny dwellings. Sex is often fatal for the males as the females are larger and often will strangle the male and drag them back to their lair to snack on for the next few days. Some of the 300 different species have developed strategies to avoid the sexual cannibalism and instead of a direct mating with their sex arm they have a penis that can detach from them and attach to the female,while others will stay in their own den and send the mating tentacle into the nearby den of a female to avoid direct contact,still others disguise themselves to appear to be female in what I think of as a sneak sex ploy. Did I mention they can also change their colors as quickly as a TV?
