Marine Cephalopod

In female squid, the ink sac is hidden from view by a pair of white nidamental glands, which lie anterior to the gills.

Squid have differentiated from their ancestral molluscs, their body plan has been condensed antero-posteriorly and extended dorso-ventrally.

The head end of the squid bears 8 arms and 2 tentacles, each a form of muscular hydrostat containing many suckers along the edge.

Squid are one of the southern water's favourite angling targets. On any given day hundreds of keen anglers are chasing these cephalopods.

New research shows that squid are the missing evolutionary link between man and Octopus.

Squid are a diverse group of invertebrates, and range in size from barely two and a half centimetres to a total length approaching 18 m.

The Colossal Squid, sometimes called the Antarctic or Giant Cranch Squid, is believed to be the largest squid species.

Giant squid have a sophisticated nervous system and complex brain, attracting great interest from scientists.

Like other cephalopods, giant squid are propelled by pushing water through its mantle cavity through the funnel, in gentle, rhythmic pulses.

1925 – Colossal Squid first discovered in the form of two tentacles found in the stomach of a sperm whale.

2003 – A complete specimen of a subadult female colossal squid was found near the surface with a total length of 6 meters.

2007 – Largest ever Colossal Squid captured by a New Zealand fishing boat off Antarctica. Length: 10 m Weight: 450 kg

Guest animal: the Moose. The animal bearing the scientific name Alces alces is known in Europe as elk and in North America as moose.

The Humboldt Squid, also known as Jumbo Squid, is a large, aggressive predatory squid found in the waters of the Humboldt Current.

A basic squid has: Two fins A mantle A head 8 arms and two tentacles, each endowed with hooks and/or suckers and sucker rings.

Some squid naturally lose the tentacles in post-larval stages, so that the adult possesses 8 arms only; some squid can have more than 2 fins

The common squid is a carnivorous mollusk belonging to the same class as the nautilus, cuttlefish, and octopus.
