The lateral line and electrosensory systems of two holocephalans.

ABSTRACT: The mechanosensory (lateral line) and electrosensory systems are two important non-visual sensory modalities, especially in low light environments. Despite their importance, these sensory systems have received little attention in deepwater chondrichthyans. Here, we describe the morphological organisation of the peripheral lateral line and electrosensory systems in two species of chimaeras; the pale ghost shark Hydrolagus bemisi (Chimaeridae) and the Australasia narrow-nosed spookfish Harriotta avia (Rhinochimaeridae), occupying depth ranges of 400-1,100 m and 260-1,278 m, respectively. Using topographic mapping, computed tomography, histology, and scanning electron microscopy, the distribution, abundance, size, and microstructure of lateral line grooves and organs (neuromasts), and ampulla
