Eponymy: Dr John Charles McCain (d: 1939) was formerly a Professor and Senior Research Scientist at the University of Petroleum and Minerals, Dhahran, Saudi Arabia, where he was the principal investigator of the Northern Area Marine Environmental Baseline [...] (Ref. 128868), visit book page.
Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino demersale; distribuzione batimetrica 91 - 500 m (Ref. 5179). Polar; 48°S - 65°S, 79°W - 84°E
Southern Ocean: Orkney and South Shetland islands to the Antarctic Peninsula. Probably more widespread in continental waters into the Weddell Sea and eastward as well as into the Pacific Ocean sector westward. Southeast Pacific: Chile (Ref. 9068).

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.

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