生物学     用語集 (例 epibenthic)

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 15.66 cm long and 8.0 cm wide (Ref. 41249). Regularly taken as bycatch in trawl hauls and may be used as fishmeal. Minimum depth from Ref. 58018.
