Ellipsosomes: organelles containing a cytochrome-like pigment in the retinal cones of certain fishes

EF MacNichol Jr, YW Kunz, JS Levine, FI Harosi, and BA Collins

Ellipsosomes are dense spherical bodies containing a very large concentration of a heme pigment spectroscopically resembling pure cytochrome c. They are located at the outer ends of the inner segments of the cones of certain fishes. Although, superficially, they resemble the similarly located oil droplets in the cones of birds and reptiles, their ultrastructure and staining properties resemble those of the neighboring mitochondria. However, like the oil droplets, they may serve as intracellular color filters.
