Comparative Development Studies On The Lateral Canal System In Cyprinus Carpio And Gambusia Affinis Affinis

Abstract

The lateral line canals and the neuromasts situated inside their lumina are described in two fishes differing in their feeding habits. There are 20 canal neuromasts in the bottom feeder Cyprinus carpio, while in the surface feeder Gambusia affinis affinis there are 8 neuromasts only. Thus the canal system is well developed in the first species than in the second one. The canals open to the exterior through fine canaliculi with fine pore which are also great in number in Cyprinus carpio.
