Summary

Cone oil droplets in the retina of the adult killifish,Fundulus heteroclitus, were investigated by light and electron microscopy. The droplets appear to be formed by mitochondrial transformations in a vitreal-scleral gradient, and the position of the mature droplet is in the ellipsoidal region nearest the cone outer segment. The mode of mitochondrial maturation and the ultrastructural configuration of the droplet differ from one type of cone to another. The latter finding is discussed in terms of the functional significance of these droplets, and the occurrence of retinal oil droplets among the teleosts is briefly reviewed.
