Squids originated from the mollusc line, and are characterised by
their distinctive head, symmetrical shape, distinct mantle (“body”) and
their tentacles. They have ten limbs - eight of which are arms, and two
of which are longer tentacles, used to grasp their prey and crack it
apart with their only solid organ - their chitin beak.
According to Wikipedia, the New Zealand Arrow Squid is also known as
the Wellington Flying Squid. Alas for this poor, unappreciated
Cephalopod, very little is known about it except for its value as a
foodstuff - for endangered New Zealand animals - like the fur seal and
the yellow eyed penguin, and also for its purpose upon our plates, in
the form of calamari.
