Korte beschrijving Morfologie | Morfometrie

Dorsale stekels (totaal): 0; Anale stekels 0; Anale zachte stralen: 0. Snout short and bluntly pointed; disc angular (Ref. 5578). Upper surface prickly only in young, nearly smooth in adults, underside smooth (Ref. 3167). Upper surface ochre to reddish-brown with scattered dark spots, underside white (Ref. 3167); two bright blue eyespots centered on the pectoral bases (Ref. 5578); may have a small dark spot on tip of snout (Ref. 2708).

Biologie     Verklarende woordenlijst (b.v. epibenthic)

Found over soft bottoms of the shelf and the uppermost slope (Ref. 5578). Depth range from 17-300 m, and up to depth of 462 m in the eastern Ionian Sea (Ref. 56504). Feed on all kinds of benthic animals, also on fish offal (Ref. 5578). 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 4.2-4.6 cm long and 2.7-2.9 cm wide (Ref. 41250). About 40-72 eggs are lain by an individual in a year (Ref. 41250). Caught by ski-boat anglers (Ref. 5578).

Life cycle and mating behavior Geslachtsrijpheid | Voortplanting | Kuitschieten | Eieren | Fecundity | Larven

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). With egg-cases laid from spring to summer (Ref. 3167). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).
