This tree diagram shows the relationships between several groups of organisms.

The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.

Containing group: Sepioidea


Members of the Sepiolida are short (mostly 2-8 cm ML), broad cephalopods with a rounded posterior mantle.

    1. Eye pore outside of ventral eyelid.
       image info

      Figure. Lateral view of head of Rossia sp., 19 mm ML, female, preserved. Arrow points to eye pore.

  2. Mantle
    1. Dorsal margin fused to or free from head.
    2. Ventral mantle adductor present.
    3.  image info

      Figure. Ventral view of mantle cavity of Rossia sp., preserved. Arrow points to the cut surface of the ventral mantle adductor where it had attached to the ventral mantle wall. Anteriorly the adductor muscles pass to either side of the intestine. Photograph by R. Young.

  3. Fins
    1. Fins broad (length ca. less than two times, usually equal to, individual fin width).
    2. Attachment of posterior fin-lobes broadly separated.

  4. Shell
    1. Shell a thin or rudimentary gladius or absent.

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, 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.
