Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 81 - 96; Épines anales: 0; Rayons mous anaux: 64 - 76. Mouth is large, with strong jaws; six caudal rays (Ref. 13359). Swim-bladder present; pelvic fins absent; several sharp spines present at lower angle of opercle; precaudal vertebrae 10 to 12; caudal fin broadly joined to dorsal and anal fins; male intromittent organ lacking ossified parts; females have genital pores (Ref. 34024).
Body shape (shape guide): fusiform / normal.
Depth range from 30-500 m (Ref. 6526) and from 460-569 m in the eastern Ionian Sea (Ref. 56504). The food of Bellottia apoda appears to be a mixture of planktonic and benthic preys (Ref. 13359). Viviparous (Ref. 6526). Uncommon species (Ref. 34024), but it is not so rare as it seemed in the Adriatic Sea (Ref. 13359).
