Tentacles are the major limbs used by squid for defense and hunting. They are often confused with arms—octopi have eight arms, while squid and cuttlefish have eight arms and two tentacles. These tentacles are generally longer than arms and typically have suckers only on their ends instead of along
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.
The Humboldt squid's diet consists mainly of small fish (lanternfish, in particular), crustaceans, cephalopods, and copepods. [31] The squid uses its barbed tentacle suckers to grab its prey and slices and tears the victim's flesh with its beak and radula. They often approach prey quickly with all 10 appendages extended forward in a cone-like ...

The squid's two feeding tentacles have suckers on them with toothed rims. [7] Sepioloidea lineolata also have glands underneath their body that can secrete a toxic slime whenever the squid is being attacked by a predator. [8] The slime scares off the predators or allows the striped pyjama squid enough time to escape.
Oral view of Berryteuthis magister, showing the arrangement of suckers. Morphologically, armhook squid are fairly uniform: all species are characterised by the suckers of their arms, which are arranged in four rows (series) rather than the typical count of two.
The squid are a reddish orange colour with a large complement of chromatophores. The suckers of the arms possess blunt teeth. On the meaty ends (clubs) of the tentacles, there are four rows of suckers; the inner two (mesial) rows are three times as large as the outer two (marginal) rows. The larger suckers have horny rings with up to 45 teeth.
