Note
Visual temporal resolution and scotopic spectral sensitivity of
three coastal shark species (bonnethead Sphyrna tiburo, scalloped
hammerhead Sphyrna lewini, and blacknose shark Carcharhinus
acronotus) were investigated by electroretinogram.
Temporal resolution was quantified under photopic and scotopic
conditions using response waveform dynamics and maximum
critical flicker-fusion frequency (CFF).
