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
These moderate-sized squids reach a maximum size of 250 mm (Nesis, 1982). They are cosmopolitan in tropical and subtropical waters although Young (1995) suggested that L. reinhardti was a mesopelagic boundary species (i.e., that it is associated with land masses). In Hawaiian waters L. reinhardti is a vertical migrator while L. valdiviae is a deep-living non-migrator (Young, 1978).
