The status of Benthalbella infans (Pisces: Myctophoidei), its development, bioluminescence, general biology and distribution in the eastern NOrth Atlantic
Evidence of comparative and developmental morphology is presented from 99 specimens from the Atlantic and Indian Oceans to establish the conspecificity of Benthalbella dubius with B. irfans. The development of the species is described from the early post‐larva (12.5 mm) through metamorphosis (60–80...
