Overview

Brief Summary

Introduction

This is a rather cyclindrical, muscular histioteuthid that is known only from five squid captured in the waters around the Hawaiian Islands.

Brief diagnosis:

A Histioteuthis ...
  • with a single sawtooth in Basal Row of photophores.
  • with virtually symmetrical outer sucker rings in ventromarginal series on club manus.

Comprehensive Description

Characteristics

  1. Tentacles
    1. Central suckers just slightly enlarged over marginal suckers.
    2. Suckers of ventral-marginal rows of manus with broad, but nearly symmetrical outer rings.

      Figure. Left - Oral view of a swath across the manus of the club of Histioteuthis sp. A, 41 mm ML, Hawaii. The small suckers on the right are carpal suckers. Right - Oral view of a ventral-marginal sucker of the club, 41 mm ML, Hawaii. Photographs by R. Young.

    3. Medial manal suckers of club with slender teeth only on distal margin of inner ring; proximal margin with small teeth difficult to see under dissecting microscope.

    Scanning electron micrographs of the arms and club suckers can be seen here.

  2. Head
    1. Photophores: Basal Row comprised of 9 photophores, and forms distinct sawtooth at left end.

    2. Beaks: Descriptions can be found here: Lower beak; upper beak.

Species of the celetaria-group are characterized by:

  1. Head and arm photophores:
    1. Type 1b pattern on head.
    2. Basal Row of head with 9 or 10 photophores.
    3. Right Basal Series of head absent.
    4. Arms IV with 3 longitudinal series on arm base (drawing below).

      Figure. Ventral view of arm IV, H. celetaria, 39 mm ML. Drawing from Voss, 1969 (Fig. 15f).

    5. Most species with separate group of 4-8 compound photophores on ends of arms IV (drawing above) (Voss, et al., 1998). Apparently this feature is absent in H. inermis.
    6. Compound photophores of large, uniform size and evenly spaced on anterior 2/3 of ventral mantle.
  2. Tubercles
    1. Absent.

The species differ in the following manner:

Character H. celetaria H. inermis H. pacifica H. sp. A
Club suckers
Asymmetrical outer
sucker rings in:
3 ventral-marginal
sucker series
No asymmetrical rings 2 ventral-marginal
sucker series
No asymmetrical rings
Size of medial
manal suckers:
Slightly larger than
marginal suckers
2 X marginal suckers 1.5 X marginal suckers Slightly larger than
marginal suckers
Large manal-sucker dentition: 12-13 teeth on distal margin 20-27 teeth on entire margin 28-32 teeth on entire margin 15-20 teeth on distal margin
Photophores
Single sawtooth in
Basal Row photophore pattern:
Yes No sawtooth No sawtooth Yes
Number of photophores in Basal Row: 9 10 9 9

With the exception of the analysis of head photophores and the inclusion of H. inermis in this species group, most of the information presented in this table is from Voss (1969) and Voss, et al . (1998)

Wikipedia

Histioteuthis

Histioteuthis is a genus of squid and the only member of the Histioteuthidae family. It goes by the common name cock-eyed squid, because in all species the right eye is normal-sized, round, blue and sunken; whereas the left eye is at least twice the diameter of the right eye, tubular, yellow-green, faces upward, and bulges out of the head.
