" The anatomy, neurophysiology, and behavioral roles of the mechanosensory lateral line system of cichlid fishes are reviewed. The lateral line system of cichlids shares fundamental anatomical features characteristic of all bony fishes and is composed of cranial lateral line canals, a trunk canal (or canals) containing canal neuromasts, and superficial neuromasts on the skin of the head, trunk, and tail. Cichlids typically have narrow cranial lateral line canals, but several genera have reduced or widened canals. A single, continuous trunk canal, which is common among bony fishes, is rare among cichlids, which typically have a disjunct trunk canal (or variations thereof) that is otherwise rare among other teleost families. Lateral line neuroanatomy and neurophysiology is well known in only a small number of cichlid species that serve as models for the study of the neuroethology of feeding and social behavior. The ability to study cichlids in the field and in the laboratory and carry out genetic and genomic analyses of complex phenotypes provides unique opportunities for novel integrative studies of the behavior and sensory ecology of these extraordinary fishes "
