Fish living in extreme environments adapt ability to see

How do variables other than light, such as temperature, affect the evolution of the visual system?  New research in PNAS by Chang lab postdoctoral fellow Gianni Castiglione et al. studied the vision pigment rhodopsin in nocturnal high-altitude catfishes, finding that the pigments kinetic rates have sped up at high altitudes in order to compensate for decreases in ambient temperature.
