Octopus vs Squid

Verb eat, nibble at, or feed on
The vampire squid, despite its fang-like features, has a surprisingly humble diet. It browses on "marine snow"—dead plankton, algae, fecal matter, goo, shells shed by tiny crustaceans, and other detritus.
Verb have sexual intercourse
Because they live at such murky depths, male squids cannot readily distinguish between females and other males, and copulate by means of a "shot in the dark" strategy.
Noun cave used as a place of shelter or concealment
The giant Pacific octopus forfeits its life for its children, refusing to leave the den while guarding more than 50,000 eggs.
Noun advance notice that something is going to happen
Small and docile, this species is recognized as one of the world's most venomous animals. The bite is small and painless, so victims often have no forewarning.
Adjective having the same relation each toward the other
Disease microbes tend to become more virulent in space. Now squid are going up in a test to see whether "good" bacteria, sharing a mutual relationship with the squid, go bad.
Adjective based on or told of in traditional stories
The giant squid lives in the deepest, coldest parts of the sea. Considered a mythical monster, it has appeared in stories for a long, long time. Now there is convincing evidence that it really exists.
Verb cause (a liquid ) to come out of a small opening in a thin, fast stream
The Dumbo octopus is quite the spectacle -- looking like a gelatinous ghost with two floppy ‘lil ear-thingies' on top. Mind it doesn't squirt you though, as its ink is toxic.
Noun thin flexible appendage in an animal for grasping or moving about
Live baby octopus are sliced up and seasoned with sesame oil. The tentacles are still squirming when served.
