deskripsi pendek Morfologi | Morfometrik

Snout is short and obtuse. Midbelt of its disc and upper surface of its tail are rough with large thorns in irregular rows. Upper surface ash gray to chocolate brown. Lower surface white, grayish white, pale gray or light fawn color, sooty patches on pelvic fins and axils of pectoral fins (Ref. 6902).

Biologi     Daftar kata (contoh epibenthic)

Found in deeper shelf and slope waters, in 3-5.5°C water temperature (6902). Benthic (Ref. 58426). Feed on all kinds of bottom animals with preference for invertebrates (Ref. 3167) like copepods, amphipods and mysids (Ref. 6902). 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 3.8-4.2 cm long and 2.4-2.6 cm wide (Ref. 41303, 41251, 41301).
