Cephalopods are often treated as 'second class' catch, but they shouldn't. Larger squids can put a really nice fight and octopus salads are often considered as delicacy.
So, if you have opportunity to go after some of these species, feel free ...
The Common Octopus is a cephalopod mollusc of the order Octopoda. They have two eyes and four pairs of arms (that is eight in total, just to be sure) with two rows of suckers. It has a very strong beak, which is capable of crushing or punching holes in various shells.
The European Squid is a large squid belonging to the family Loliginidae. Although this species is extensively exploited by commercial fisheries, it is also commonly targeted by recreational fishermen, often with great success.
