Aug. 3 - A squid that lives deep in the northern Pacific Ocean has evolved a lizard-like approach to self-defense. The foot-long octopus squid (Octopoteuthis deletron), jettisons its arms when confronted by a predator, creating a diversion for escape. The creature's defense strategy was observed for the first time by University of Rhode Island researcher Stephanie Bush. Kilmeny Duchardt reports.
The octopus squid is much like any other of its class ..until it meets a predator, in this case a bottle brush. After counter-attacking, the squid flees, leaving its hooked tentacle behind as a diversion, tricking its attacker long enough to escape. Like a lizard, the squid then regenerates its lost limb, behaviour never observed in a squid species before. Kilmeny Duchardt, Reuters.
