The mean female size is 1.921 mm (n = 36; SD = 0.2264), and the mean male size is 1.508 mm (n = 12; SD = 0.2012). The size ratio (male : female) is approximately 0.81.
Rem.: epi-mesopelagic, 3000 m (Medit.: off Malta). Sargasso Sea: 0-500 m. (Deevey & Brooks, 1977, Station "S"). For Acha & al. (2020) this species is observed offshore on shelfbreak in front of Rio de La Plata (Argentina).
After Moraitou-Apostolopoulou (1985, p.309), due to the homothermal conditions in December on the coast of Israel, this deep water species appears in the planktonic community.

After Lapernat & Razouls (2002, p.19) the Itoh's index value = 353.2 (number of teeth: 9).
After Benedetti & al. (2018, p.1, Fig.2) this species belonging to the functional group 2 corresponding to small ambush feeding carnivorous.
