Liguriella podophtalmaRichard E. Young and Katharina M. Mangold (1922-2003)
Liguriella contains one recognized species. Voss, et al. (1992), however, suggest that two or more species exist.
These are moderate sized squid, reaching at least 243 mm ML (Voss, et al. 1992). Little is known about their biology.
A taoniin ...
- with contiguous ocular photophores.
- with short fins.
- with tubercules at funnel-mantle fusion.
- Tentacular club with suckers only.
- Carpal cluster absent.
- Two series of suckers and knobs on tentacular stalk.
- Funnel valve absent
- Funnel organ: Dorsal pad with three papillae.
- Tubercles present at funnel-mantle fusion.
- Posterior insertion of fins at distal end of gladius.
- All but anterior margin of fins insert on vanes of gladius.
- Two contiguous photophores (one large, one small) on each eye.*
- Arm tip photophores absent.
*Unusual within family; shared with Sandalops.
Characteristics are from Voss (1980).
Voss, et al. (1992) illustrated a paralarva and a juvenile but state that only subadults and adults can be confidently identified. Note the elongate "club" of the paralarva.
The genus occurs circumglobally in tropical and subtropical oceans (Voss, et al. 1992).
