Abstract
Components of the lateral line system and their innervation were examined in Glossogobius olivaceus (Gobiidae), with almost all of the trunk scales bearing a row of superficial neuromasts, the latter comprising some 2,900 of the total (ca. 4,800) neuromasts on the body. The relationship between orientation and innervation of the superficial neuromasts on the head showed the buccal and mandibular rami to be clearly separated. On the trunk, the lateral ramus detached a number of branches, typically comprising dorsal, lateral and ventral ramules, to innervate neuromasts. Extensively distributed neuromasts were considered as an adaptation to a nocturnal habit, compensating for reduced vision.
