Cephalopod eight or ten. Decapods such as cuttlefish and squid have five pairs. The longer two, termed "tentacles", are actively involved in capturing prey; they can lengthen rapidly (in as little as 15 milliseconds). In giant squid they may reach a length of 8 metres. They may terminate in a broadened, sucker-coated club. The shorter four pairs are termed "arms", and are involved in holding and manipulating the captured organism. They too have suckers, on the side closest to the mouth; these help to hold onto the prey. Octopods only have four pairs of sucker-coated arms, as the name suggests, though
Giant squid and on "Giant Squid: Filming the Impossible – Natural World Special" on BBC Two. The squid was about long and was missing its feeding tentacles, likely from a failed attack by a sperm whale. It was drawn into viewing range by both artificial bioluminescence created to mimic panicking Atolla jellyfish and by using a "Thysanoteuthis rhombus" (diamond squid) as bait. The giant squid was filmed feeding for about 23 minutes by Tsunemi Kubodera until it departed. The technique of using unobtrusive viewing and bioluminescence luring of the squid with quiet unobtrusive platforms was described by Edith Widder, a member of
