जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Found in deeper slope waters (Ref. 4426), but mainly around 200 m (Ref. 3167, Ref. 114953). Found on sand and sand-rock bottoms (Ref. 6808). Feeds on all kinds of bottom animals (Ref. 3167), mainly cephalopods and crustaceans (Ref. 114953). Minimum depth reported taken from Ref. 6808. Become sexually mature at a length of about 120 cm (Ref. 35388); young hatch at ca. 17 cm TL (Ref. 114953). Breeds in spring and early summer (Ref. 114953). 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 14.0-23.5 cm long and 11.0-12.0 cm wide (Ref. 41251, 41304).

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