    Asperoteuthis have many similarities to Grimalditeuthis; however a major difference that exists is the presence of many small suckers at the outer end of the tentacle club. (Where as Grim's do not have any suckers on their clubs). Asperoteuthis have what appears to be a secondary fin along their tail (which could be a flotation device as is thought to be the case in Grimalditeuthis). These squid can get fairly large, and have been seen swimming below 1000 m depth.

    @Heather Braid is currently doing some research on the systematics and genetics of this genus right now, and hopefully she can shed some more light on how cool these are!

    These squid are extremely cool! Asperoteuthis acanthoderma is the one that gets really big, but then there is A. mangoldae that is really quite little in comparison. My favourite species is A. lui, who was described from the head of a single squid that came out of the stomach of a ling (a big pink fish) and it was missing the funnel and one tentacle, but it had both eyes. The taxonomy in this genus is about to be shaken up so watch this space!
