Containing group: Chiroteuthis


C. joubini occurs in the tropical to subtropical waters of the Atlantic and Indian Oceans. It is separated from its closest relatives by the shortness of the proximal section of the tentacular club and by the lack of globular arm suckers.


A Chiroteuthis ...


  1. Arms
    1. Large arm suckers with 22-26 pointed, triangular teeth, in contact at bases, over distal 2/3 of ring.
    2. Largest suckers not globular.
  2. Tentacular clubs
    1. Suckers with 7-8 pointed teeth, in contact at bases, over distal 1/2 of ring; no enlarged central tooth.
    2. Suckers with stalks in two distinct parts; stalks of lateral suckers about equal in length to stalks of medial suckers.
    3. Protective membranes
      1. Membranes in three distinctive sets.

      2. Proximal set with 7-12 trabeculae (14-18% of club length).
      3. Middle set without distinct trabeculae but opposite 9-12 marginal suckers (32-36% of CL).
      4. Distal set with 20-21 trabeculae (46-54% of CL).
  3. Photophores
    1. Eyeball with oval organs in 2 series: lateral series= 5 or 6 organs; 1(enlarged)+4(or 3)+1; medial series = 5 or 4+1. Formula reads from posterior to anterior.
    2. Viscera: two, large photophores.
  4. Pigmentation
    1. Club sucker stalks with epithelial pigment but not pleated; epithelial pigmentation diminishes then disappears in distal portions of club.


More details of the description of C. joubini can be found here.


This species was originally described by Joubin (1933) although he identified it as C. lacertosa. Voss (1967) recognized that Joubin's specimen did not conform to the true C. lacertosa (= C. veranyi), nor to any other described species, so he renamed it as a new species. Joubin's description becomes the type description and Joubin's specimen is the holotype of C. joubini.

Life history

Paralarval stages are unknown.


The type locality is the tropical North Atlantic at 8°N, 44°W. This species is known from the temperate north to temperate south Atlantic Ocean.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
