... with reflecting superposition optics. These eyes view the world through an orbital hood that is 80–90% as transparent as seawater across visible wavelengths (400–700 nm). Through electroretinography and microspectrophotometry, we found the eyes of A. heterochaelis have a temporal sampling rate of >40 Hz...
