Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 0; Afterflossenstacheln 0; Afterflossenweichstrahlen: 0. Eyes conspicuously small; dorsal fins close-set, no thorns between; upper surface predominantly spinulose, underside almost smooth in young, but head and centre of disc prickly in larger specimens; orbital thorns separate, a regular row of about 50 thorns from nape to first dorsal fin; upper surface greyish, olive to light brown with light blotches and long bands, underside white (Ref. 3167).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Found on sandy bottoms, from inshore waters to about 100 m in tidal areas (Ref. 3167). Feed on fishes (Ref. 3167). Oviparous. 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 6.6-10.0 cm long and 4.1-6.3 cm wide (Ref. 41250). About 54-61 eggs are laid by an individual in a year (Ref. 41250).

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

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).
