How can you tell the gender of a Squid?
Squid have two long tentacles which are used to catch prey plus eight shorter arms. On a male Squid the tips of one or both of the two longest arms (not the tentacles) have a toothbrush, or picket fence, like appearance in place of the normal round suckers. Female Squid however have normal round suckers right to the end of all eight arms. The same applies to Octopus and Cuttlefish, which are also members of the cephalopod family.
