Apparently, if you search Etsy.com for “squid necklace” you get over three-hundred product listings. I guess it’s a genre. Although I’ve never seen anyone wearing squid jewelry in real life.
The “deep space squid necklace” is described by a series of unrelated cephalopod factoids, but doesn’t say how awesome it will make your neck look.
Not to be confused with the “deep space cuttlefish necklace” which has no where the same sort of class.
