In bony fish (Teleosts): Gills lie in a branchial cavity covered by the operculum: Usually two sets of four holobranchs. Each holobranch consists of two hemibranchs(âhalf gillâ): Anterior and posterior. Hemibranchs consist of a row of long filaments (primary lamellae) with semilunar folds (secondary lamellae).chematic of the teleost fish gill.
