Ontogenetic changes in the body structure of the Arctic fish Leptoclinus maculatus
Histological studies of the ontogenetic changes in Arctic marine fishes are often fragmented and incomplete. Here we present a comprehensive histological ontogenetic analysis of the daubed shanny ( Leptoclinus maculatus ) from the Arctic, characterizing its development as it undergoes a series of ch...
