The giant squid is widespread, occurring in all of the world's oceans. It is usually found near continental and island slopes from the North Atlantic Ocean, especially Newfoundland, Norway, the northern British Isles, Spain and the oceanic islands of the Azores and Madeira, to the South Atlantic around southern Africa, the North Pacific around Japan, and the southwestern Pacific around New ...
Two distinct behaviors have been observed in inking cephalopods. The first is the release of large amounts of ink into the water by the cephalopod in order to create a dark, diffuse cloud (much like a smoke screen) that can obscure the predator's view, allowing the cephalopod to make a rapid retreat by jetting away.
Decapods such as cuttlefish and squid have five pairs. The longer two, termed "tentacles", are actively involved in capturing prey; [1]: 225 they can lengthen rapidly (in as little as 15 milliseconds [1]: 225 ). In giant squid, they may reach a length of 8 metres. They may terminate in a broadened, sucker-coated club.
An ink sac is an anatomical feature that is found in many cephalopod mollusks used to produce the defensive cephalopod ink. With the exception of nocturnal and very deep water cephalopods , all Coleoidea (squid, octopus and cuttlefish) which dwell in light conditions have an ink sac, which can be used to expel a cloud of dark ink in order to ...
The image was published in the 1993 book European Seashells by Guido T. Poppe and Goto Yoshihiro, where it was identified as Architeuthis dux, the giant squid, and said to have been taken in the North Atlantic. [12] [clarification needed] If true, this image would represent the earliest known photograph of a live giant squid. [11]
The story was validated by Commander Arne Groenningsaeter of the Royal Norwegian Navy, stating that the ship had not one, but three encounters with giant squids between 1930 and 1933. [23] A giant squid allegedly attacked a raft with survivors from the Britannia in 1941, which had been sunk in the South Atlantic. One of the men was dragged away ...
An article here states that "the giant squid has only a small ink sac" but another site states that "There is also the possibility that the giant squid don't even have an ink sac, which is often the case with deep-dwelling squid". Anyone have more definitive data? Maximoff77 01:18, 8 November 2006 (UTC) Yes, they do have an ink sac
The giant squid nevertheless remains a rarely encountered animal, especially considering its wide distribution and large size, [60] with Richard Ellis writing that "each giant squid that washes up or is taken from the stomach of a sperm whale is still an occasion for a teuthological celebration".
