Kondakovia is a sub-Antarctic to true Antarctic genus of large squids (adults to 740 mm ML), primarily set apart from similar species in Onykia by the presence of marginal sucker series on the tentacular clubs in subadults to adults.
An onychoteuthid ...
- with marginal suckers throughout club in subadults (unique character).
- without gladius visible beneath skin in dorsal midline.
- with 3 occipital folds.
- with fleshy longitudinal dermal ridges (K. longimana) or reticulate structure (K. nigmatullini) on the surface of the mantle.
- Tentacular club with 23-33 hooks flanked by complete series of small marginal suckers.
- Mantle soft and fleshy.
- Mantle skin with longitudinal ridges in large specimens of K. longimana (Clarke, 1980) and reticulate skin in K. nigmatullini (Laptikhovsky, Arkhipkin & Bolstad, 2008). The photographs below compare the skin of K. longimana (left, middle) with the skin of Onykia robsoni (right).
- Gladius not visible beneath skin in dorsal midline.
- Gladius thin and fragile with 3 pairs of narrow longitudinal ribs: one borders rhachis, one at marginal rim and one inbetween the other two.
- Gladius rostrum 5-13% of ML (Laptikhovsky, Arkhipkin & Bolstad, 2008); 2-5% of ML (Clarke, 1980).
- Gladius rostrum tricornate dorsally in cross-section along conus field; convex rib present over full length of flat dorsal surface.
This genus is thought to occupy epi- and mesopelagic waters in the Southern Ocean, where it may be circumpolar and reach northward to South Georgia and the Tasman Sea (Kubodera et al. 1998).
