Light and electron microscopy of oil droplets and MMOD-complexes. (A) Image of a white-throated sparrow (Zonotrichia albicollis) retina wholemount under light microscopy showing the five traditional oil droplets types. (B) Image of an Acadian flycatcher (Empidonax virescens) retina wholemount under light microscopy showing the five traditional oil droplet types and the additional orange, conical structures belonging to the newly described photoreceptor. (C) Transmission electron microscopy image of the orange, conical structures reveals that they are electron-dense megamitochondria surrounded by many small oil droplets. The white asterisk denotes the megamitochondria, the orange arrows denote the small oil droplets that provide the orange coloration seen in panel (B), and the blue arrow indicates a traditional oil droplet from the neighboring photoreceptor. The retinae in panels (A,B) have not been stained or artificially labeled in any way.
