О строении кожных желез некоторых медленноплавающих рыб

Abstract

Comparative and morphological studies revealed a similarity in structure and topo graphy of the secretory apparatus of common integument in benthic forms of Euselachiae representatives and in certain Neopterygii (sting ray and plaice). This likeness is explai- ned by similar ecology and the same functional loadings of the mucous substance covering the body of these fishspecies.
