Some seafood produce tunes because of the rubbing or grinding the skeleton together with her. One of several cartilaginous fishes, sharks of your family Lamnidae (such as the great light shark) and you may Alopiidae (thresher sharks) try endothermic. Specific fish, such as catfish and you will sharks, feel the ampullae away from Lorenzini, electroreceptors one locate weak electric currents for the order away from millivolt.
