abstract：:We studied the development of multibank rod retinae by monitoring the size-related addition of new layers of rod inner and outer segments in four species of deep-sea fishes and found two different growth paradigms. In the mesopelagic Chauliodus sloani, new banks of rod inner and outer segments are added as long as the...
