Abstract
The anatomy of the fish ciliary body and the distribution of sodium-potassium-activated adenosine triphosphatase in the elasmobranch (Squalus acanthias) eye were studied in an attempt to localize the site of formation of aqueous humor. Both teleosts and elasmobranchs have a ciliary body with a nonpigmented and pigmented epithelium similar to the mammalian pars plana. The fish ciliary body has no processes and little or no smooth muscle. Sodium-potassium-activated adenosine triphosphatase was found in significant levels in the elasmobranch retina, ciliary body and brain, while the iris had little activity. If the elasmobranch eye is similar to the mammalian eye and sodium transport is involved in aqueous humor formation, the ciliary body seems the most likely site of transport.
