Fig. 4. Cranial nerves of the electric eel Electropholuls, which is a gymnotid.
The anterior lateral line nerve innervates cranial electroreceptors (and canal organs)
and sends a branch posteriorly to innervate all the caudal electroreceptors as well. The
posterior lateral line nerve innervates only mechanoreceptors of the lateral line and
free neuromasts if present. From De Oliveira Castro ( 1961 ).
nett, 1967; Suga, 196%) which come from free neuromasts and canal
organs (see Chapter 8 by Flock, this volume).
The electroreceptors of catfish are distributed over the entire body
surface but tend to be concentrated in the head region (Fig. 5; Dijkgraaf,
1968). Receptors are even found on the fins. Innervation of the receptors
