Larger immature and adult individuals grey with numerous small white spots above, underside white with no black pores; hatchlings plain reddish-brown above, often with blue spots, and white below with broad dusky grey margins on disc [536].

Human uses
fisheries: minor commercial; gamefish: yes; price category: medium; price reliability: very questionable: based on ex-vessel price for species in this family

Oviparous, paired eggs are laid. Embryos feed solely on yolk [733]. Eggs are laid in huge cases and take up to 18 months to hatch [536]. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother [17086].
