Abstract
The superficial neuromasts inLeptocottus armatus (Pacific staghorn sculpin) andOligocottus maculosus (tidepool sculpin) are depressed below the rim of an epidermal collar, whereas the superficial neuromasts inPsychrolutes paradoxus (tadpole sculpin) are surrounded by a pair of hillocks. The lateral line canal system appears identical across these species, whereas the system of superficial neuromasts shows some intraspecific variation. The sand-livingLeptocottus has a more highly developed system of superficial neuromasts thanOligocottus, which lives in a rocky habitat. The present results support the correlation between lateral line system morphology and habitat features previously postulated by Dijkgraaf.
