Combfin squidRichard E. Young and Michael Vecchione
Three species are presently recognized in the family but more are known to exist:
- Chtenopteryx canariensis Salcedo-Vargas and Guerrero-Kommritz 2000
- Chtenopteryx sepioloides Rancurel 1970
- Chtenopteryx sicula (Verany 1851)
A number of undescribed species are present in this genus. Little is known of the biology of any species.
A member of the bathyteuthid families ...
- with buccal connectives attaching to ventral border of arms IV.
- with long fins containing muscular ribs.
- Dorsal six arms with suckers in six or more series at some point on arms.
- Buccal connectives attach to the ventral margins of arms IV.
- Tentacular club
- Suckers in 8 or more irregular series.
- Membranes connect slender muscle bundles (fin ribs) to produce comb-like appearance.
- Fins attach to lateral walls of mantle.
- Fins extend nearly full length of mantle.
- Large oval photophore on viscera (except in C. canariensis and in C. sicula).
- Large photogenetic patches on eyeball (except in C. canariensis).
- Females with an accessory nidamental gland.
CommentsOnly a few species-level characters are known in this genus. At present species are separated by (1) the maximum number of sucker series on the arms and tentacular clubs, (2) the presence/absence of photophores, (3) the size of the visceral photophore and (4) the mantle width relative to the ML.
Vertical distributionIn Hawaiian waters relatively few captures were made during the daytime but they suggest that Chtenopteryx "sicula" occupies depths from about 600-1000 m while at night it migrates mostly into the upper 200m (Young, 1978).
Geographical distributionSpecies are found throughout the tropical and subtropical waters of the world's oceans (Nesis, 1982).
