Grimpoteuthis meangensis (Hoyle, 1985)

Richard E. Young and Michael Vecchione
Containing group: Grimpoteuthis


Grimpoteuthis meangensis was originally described from a single, damaged animal of unknown sex. A full illustration was never made. Subsequently Hoyle (1886) illustrated a small octopod from the South Pacific (over 2000 km south of the type locality) which he assummed to be the same species. However, considering the variety of species now known to exist, this identification may not be valid and is not included in the description here. A redescription based on new material is badly needed.

    Figure. Oral view of an arm and associated web of G. meangensis. Drawing from Hoyle (1886).

    1. Each arm with 60-70 suckers.
    2. Suckers small, subequal, spaced at equal intervals except at crowded arm tip.
    3. Web attaches to dorsal side of arm at 90% of arm length; web attaches to ventral side of arm at 80% of arm length.
    4. Single web nodules present, small. Appears (from drawing) to attach near sucker 33.
    5. Cirri short, 2 mm in length.
    6. First cirri appear between suckers 4 and 7. Cirri could not be seen at arm tips.

      Figure. Lateral view of an arm of G. meangensis. Drawing from Hoyle (1886).

  2. Eyes
    1. Large.

  3. Fins
    1. Length approximately equal to body width.

  4. Shell
    1. In describing apparently the saddle, Hoyle states, "inner surface rounded off whereas the outer is flat."
    2. Illustration suggests well-developed shoulder blades.
    3. Illustration suggests wings not expanded.

      Figure. Shell of G. meangensis. Top - Dorsal (?) view. Bottom - Posterior view of saddle. Drawings from Hoyle (1886).

  5. Measurements, mm
    • Mantle width - 30
    • Fin length - 30
    • Fin width - 10
    • Largest sucker diameter - 1
    • Diameter of eye - 12
    • Arm I, length (right/left) - 100/100
    • Arm II, length - 94/100
    • Arm III, length - 80/92
    • Arm IV, length - 90/92


The above description is taken from Hoyle (1986). The shape of the shell separates this species from many of the other species in the genus.

Among Pacific species, G. meangensis differs from:


Type locality: Off Meangis Islands, near Philippines, 4°33'N, 127°06'E, 925 m.

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.
