The Love Life of an Octopus

An octopus slithers into a narrow crack near the shore we see its eye up close It feeds on a crab In spring its time to mate A male grabs a female he inserts his third arm in her respiratory cavity We watch another pair a larger female is the aggressor here Mating is repeated over hours and days The female releases strings of fertilized eggs that hang from the roof of a nest She guards her spawn for a month fanning the strings to circulate water for oxygen and cleanliness
