Introduction


Figure. Ventral view of A. siedleckyi, holotype.
Drawing from Lipinski (1983).

A. siedleckyi may be a southern temperate species. It resembles, however, the tropical Pacific A. heminuchalis and they may prove to be the synonymous.

Characteristics

 
  1. Tentacle clubs
    1. Two or three hooks on ventral side.
    2. Two rows of large suckers on dorsal side of manus.

  2. Hectocotylus
    1. Left ventral arm of male hectocotylized.
    2. Hectocotylus with two different sized off-set flaps: an elongate, proximal flap on ventral margin and much shorter, distal flap on dorsal margin.

  3. Eye Photophores
      1. Five complex organs: two terminal, opaque organs and three intermediate silvery organs.
      2. Posterior opaque organ much larger than others; anterior opaque photophore about the same size as the largest intermediate organ.

        Figure. Ventral view of the ocular photophores of A. siedleckyi, holotype. Drawing from Lipinski (1983).

    1. Integumental Photophores
      1. Arms IV with scattered photophores between the two photophore series (the series on the edge of the lateral memberane constitutes a third series).
      2. Ventral mantle and head with scattered arrangement of integumental organs.

    2. Mantle apex ("tail")
      1. Broad and extends well beyond conus of gladius.
    3. Reproductive structures
      1. The incomplete nuchal cartilage in an immature female suggests a developing spermatangia receptacle similar in structure to that of A. heminchalis and A. veranyi.

Distribution

Geographical distribution

Information on distribution is scarse. The type locality is off southwest Cape, South Africa at 39°05'S, 13°43'E. A very similar specimen was collected from the southeast coast of Australia.

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.
