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.
You can click on the root to travel down the Tree of Life all the way to the root of all Life, and you can click on the names of descendent subgroups to travel up the Tree of Life all the way to individual species.close box
Traditionally only a single species, C. murrayi, was placed in this genus. O'shea (1999) placed Cirroteuthis magna in this genus on the basis of the similarity of the shells in the two species. These are fragile, gelatinous deep-sea cirrates.
A cirroteuthid ...
- with shell with moderate saddle and triangular wings.
- with normal eyes (with lenses) or reduced eyes lacking lenses.
- Eyes: Eyes well developed, lenses present (C. magna) or poorly developed, without lenses (C. murrayi).
- Beaks: See C. magna.
- Web nodules absent.
- Suckers extend to arm tips.
- Cirri may extend to arm tip (C. murrayi) or terminate at web margin (C. magna).
- Shell saddle-shaped but with a saddle of moderate length.
- Shell with anterior-posterior length of wings more than 2.5 times length of saddle in this direction.
- Shell with wings triangular in lateral view (below).
