		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 boxIntroduction
These are small (22 mm ML max.), muscular squids that occupy neritic waters often in association with small patch reefs and seagrass (Voss, 1953). In spite of the accessible habitat, the squid is rarely captured and little is known of its biology.
Brief diagnosis:
A loliginid ...
- of small size and with posterior fin lobes; fins not joined posteriorly.
- with club suckers on manus in two series.
Characteristics
- Arms     - Suckers in two series.
 
 
 
- Suckers in two series.
- Tentacles       - Club suckers on manus in two series; suckers on dactylus in four series or in two series.
 
- Head   - Buccal supports without suckers.
 
 
 
- Buccal supports without suckers.
- Fins     - Fins subterminal.
- Fins oval with free anterior and posterior lobes.

- Photophores - Absent.
 
Comments
The general shape varies greatly between species. P. pulchella is broad with relatively large arms and fins; P. bayeri and P. vossi are slender with small arms and fins. The latter two look look much like a young Doryteuthis.
Brakoniecki (1996) submerged the family Pickfordiateuthidae into the Loliginidae.
