The daubed shanny, Leptoclinus maculatus (Fries 1838), is an arctic-boreal fish species and widely distributed in Svalbard waters. The ecological role of L. maculatus is determined by its complex life cycle—adults are bottom-dwelling while the young are pelagic—which indicates its place in the Arctic trophic food webs, both pelagic and benthic. As...
