Extracellular recordings have been made from ganglion cells of the lemon shark retina: ON, OFF and ON-OFF units were recorded. Spectral sensitivity measurements under darkadapted conditions reveal a λmax of 519-522 nm. This may be due to two photoreceptor systems. A second class of ganglion cells was characterized as receiving input from a single 544 nm visual pigment system.
