In several species of fish, inbreeding was found to decrease reproductive success. The gills are carried right behind the head, bordering the posterior margins of a series of openings from the pharynx to the exterior. Vesicles of the forebrain are usually paired, giving rise to hemispheres like the cerebral hemispheres in mammals. {code: 'ad_btmslot_a', pubstack: { adUnitName: 'cdo_btmslot', adUnitPath: '/2863368/btmslot' }, mediaTypes: { banner: { sizes: [[300, 250], [320, 50], [300, 50]] } }, Usage explanations of natural written and spoken English, 0 && stateHdr.searchDesk ?
