簡単な記述 検索表 | 形態学 | 形態計測学
Brown dorsally, mottled with white and black spots, and a large dark blotch on each wing; white ventrally (Ref. 26346).
Inhabit the continental shelf and upper slope (Ref. 26346); usually in coastal waters (Ref. 9258). Found partially buried in sand (Ref. 26346). Feed on fish, shellfish, crabs, and worms (Ref. 114953, 26346). 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 10.2-12.7 cm long and 6.3-8.3 cm wide (Ref. 41249, 41308).
Life cycle and mating behavior 成熟 | 繁殖 | 放精 | 卵 | 生産力 | 幼生
Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Young hatching at about 18-20 cm (Ref. 26346). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).
