Sixth sense in the deep-sea: the electrosensory system in ghost shark Chimaera monstrosa

Sixth sense in the deep-sea: the electrosensory system in ghost shark Chimaera monstrosa Bottaro, M. ABSTRACT: Animals that continually live in deep sea habitats face unique challenges and require adaptive specializations solutions in order to locate and identify food, predators, and conspecifics. The Ampullae of Lorenzini are specialized electroreceptors used by chondrichthyans for important biological
