Biology
Oviparous, paired eggs are laid. Embryos feed solely on yolk [733]. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother [17086]. Eggs have horn-like projections on the shell [17086]. Feeds on fish, cephalopods, benthic invertebrates, zooplankton and detritus [5868].
