Short description Morfología | Morfometría

Disk without spines, except near edge of pectoral fins in males. Ventral mucous pores not blackish. Tail with middorsal row of large spines. Snout pointed (Ref. 7251).

Biología     Glosario (por ej. epibenthic)

An inhabitant of deep, cold water (Ref. 7251). Benthic (Ref. 58426). Feed on all kinds of bottom animals (Ref. 3167). Oviparous (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 13.4-16.5 cm long and 8.0-10.2 cm wide (Ref. 41251, 41301).

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

Oviparous (Ref. 3167). Paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).
