I think it was modelled off a bobbit worm "eunice aphroditois". The attack style and speed etc are very similar and they reckon they can grow to 3M long


There seem to be at least two creatures; Joey is chased off the boat at the same time Finnigan is fighting the big one in the banquet hall. Also of note is that the tentacle that eats Hanover seems to taper down toward the rear as if it were a worm. My best speculation is that the large adults spawn by parthenogenesis, growing smaller clones as tentacles ...
