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 horned ring of the largest tentacle has 20-30 sharp teeth, and the arrangement is 6-12 large teeth interspersed with 1-4 small teeth. [7] U. chinesis can emit light, [8] [9] and the illuminators are on both sides of the rectum and are spindle shaped. [9] Squid are also known to be sensitive to temperature, salinity, and circulation in the ...
The teeth may be homodont (i.e. similar in form across a row), heterodont (otherwise), or ctenodont (comb-like). [102] Their height, width and number of cusps is variable between species. [102] The pattern of teeth repeats, but each row may not be identical to the last; in the octopus, for instance, the sequence repeats every five rows. [102]: 79

[ 2 ] [ 3 ] The vampire squid uses its bioluminescent organs and its unique oxygen metabolism to thrive in the parts of the ocean with the lowest concentrations of oxygen.
The beak of a giant squid. All extant cephalopods have a two-part beak, or rostrum, situated in the buccal mass and surrounded by the muscular head appendages. The dorsal (upper) mandible fits into the ventral (lower) mandible and together they function in a scissor-like fashion. [1] [2] The beak may also be referred to as the mandibles or jaws ...

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]
