Abstract
In Esomus dandricus (Ham.), 4 pairs of gills are present with secondary lamellae having a thin lamellar epithelium. The space, which is present in between the proximal margin of gill filaments and branchial septum, forms the so-called water channels to distribute water along the length of the gill filaments. Number of mucous glands and taste buds are present on the gill- rakers and gill head region. The gill filaments of the two-hemi branches are long and alternately arranged to each other, unequal in length and are separated by a comparatively long interbranchial septum (covering about 42% of the total length of the filaments). Tertiary lamellae are absent. Keywords: Fish, Esomus dandricus, Respiratory organsdoi:10.3126/on.v1i1.305Our Nature (2003) 1: 49-52
