Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 14; Μαλακές ραχιαίες ακτίνες (συνολικά) : 13 - 14; Εδρικές άκανθες: 2; Μαλακές εδρικές ακτίνες: 13 - 14.
Known only on the basis of specimens caught by a shrimp trawl in 99 to 183 meters (Ref. 7247). Life history characteristics for the family specify that this group is oviparous, with distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
