“Bathyteuthis abyssicola, Hoyle
Bathyteuthis abyssicola, Hoyle, Narr. Chall. Exp., vol. i. p. 272, fig. 108, 1885.
The Body is subcylindrical, somewhat narrowing towards and bluntly rounded at the posterior extremity. The fins are small, separate; each is somewhat rectangular in shape, with rounded angles, and attached to the body by one angle.
The mantle-margin is almost transverse, but projects slightly on the dorsal median line, and forms a shallow sinus behind each eye and the siphon. The mantle-connective consists of a long linear ridge, extending quite to the margin, and fitting into a similar but somewhat shorter and broader groove on the base of the siphon, which is short, tapering, and bluntly pointed, fits into a shallow depression below the head, but has no dorsal bridles.
The Head is much broader than the body, being distended laterally by the enormous eyes which look outwards and forwards, and have bright, prominent, glistening lenses.
The Arms are unequal, the order of length being 4, 3, 2, 1, and about one-fourth the length of the body: they are all conical and taper to slender points; each has a distinct angle along the outer side, which expands to a distinct web in the fourth pair; there is also a very narrow delicate web along each side of the sucker bearing face. The suckers are very minute, pedunculate, and are arranged in to rows, almost embedded in the arm: they are spheroidal, and have a smooth horny ring, surrounded by two or three rows of conical papillæ. The hectocotylus was not present. The buccal membrane is very large, has the usual seven points, connected by ligaments with the arms; each joint bears one or two suckers.
The Tentacles are almost equal in length to the head and body together; the stem is very slender, cylindrical, and grooved along the inner aspect; they taper way rapidly towards the extremity, no club being formed: the suckers cover on the distal eighth of the tentacle in its inner aspect: they are smaller than those of the sessile arms, and almost imperceptible to the naked eye; they are urn-shaped, and have a smooth horny ring, surrounded by about two rows of very small papillæ.
The Surface is covered with minute wrinkles, probably due to the action of the spirit.
The Colour is a very deep purplish brown.
The Gladius was unfortunately somewhat damaged; for the anterior two-thirds it resembles that of an Ommastrephes, but posteriorly it expands into a broad blade, resembling that of Loligo; it was impossible to ascertain whether it forms a terminal cone.

Bathyteuthis abyssicola, also known as the deepsea squid, is a species of squid in the family Bathyteuthidae.
Bathyteuthis abyssicola is the type species of Bathyteuthis. It is a small (less than 8 cm mantle length), deep maroon-colored squid that inhabits the meso- and bathypelagic zones of all oceans of the world, and is particularly abundant in the Southern Ocean where it seems to be the dominant small deep-sea squid. B. abyssicola normally occurs at depths from 700–2,000 m (2,300–6,600 ft), but has been recorded from 100–4,200 m (330–13,780 ft).
The arms of B. abyssicola are short, with blunt tips. Protective membranes are low, fleshy, without free trabeculae (beam- or finger-like protuberances). Suckers are relatively few in number, about 100 on each of the upper six arms (pairs I–III). Sucker rings on the arms have 8–18 separated, bluntly rounded to truncate protuberances. The tentacles and clubs are relatively short. Gills are short and narrow.
They have large photosensitive vesicles just behind the eyes which appear to detect bioluminescence. These photosensitive vesicles are among the largest known in any cephalopod.

Bathyteuthis abyssicola from the Ross Sea of Antarctica ()
Bathyteuthis abyssicola Hoyle, 1885 è una specie di calamaro appartenente alla famiglia Bathyteuthidae, della quale è la specie tipo[1].
È un calamaro di piccole dimensioni, la lunghezza del mantello non supera gli 8 cm, è di colore granata.
Abita le zone mesopelagiche e batipelagiche di tutti gli oceani del mondo, ed è particolarmente abbondante nell'Oceano Australe dove sembra essere il dominante tra i piccoli calamari di profondità. B. abyssicola si trova normalmente a profondità comprese tra i 700 e i 2.000, ma è stato visto anche fino a 4.200 m.
Le braccia degli esemplari di B. abyssicola sono corte, con punte smussate. Le membrane protettive sono sottili, carnose, prive di trabecole libere (protuberanze a forma di trave o dito).Le ventose sono relativamente poche di numero, circa 100 su ciascuna delle sei braccia superiori. Gli anelli a ventosa sulle braccia hanno dalle 8 alle 18 protuberanze separate, con protuberanze che possono essere smussate o troncate di netto. I tentacoli e le clavette sono relativamente corti. Le branchie sono corte e strette.
Hanno grandi vescicole fotosensibili appena dietro gli occhi, sembrano poter rilevare la bioluminescenza. Queste vescicole fotosensibili sono tra le più grandi conosciute in qualsiasi cefalopode[2].
Bathyteuthis abyssicola Hoyle, 1885 è una specie di calamaro appartenente alla famiglia Bathyteuthidae, della quale è la specie tipo.
Bathyteuthis abyssicola is een soort in de taxonomische indeling van de inktvissen, een klasse dieren die tot de stam der weekdieren (Mollusca) behoort. De inktvis komt enkel in zout water voor en is in staat om van kleur te veranderen. Hij beweegt zich voort door water in zijn mantel te pompen en het er via de sifon weer krachtig uit te persen. De inktvis is een carnivoor en zijn voedsel bestaat voornamelijk uit vis, krabben, kreeften en weekdieren die ze met de zuignappen op hun grijparmen vangen.
De inktvis komt uit het geslacht Bathyteuthis en behoort tot de familie Bathyteuthidae. Bathyteuthis abyssicola werd in 1885 beschreven door Hoyle.[1]
