“…The cell-cluster pattern was not altered in air-exposed fish. Sturla et al (2001) observed MRC clusters of about three to five cells in the opercular skin of FW African lungfish (Protopterus annectens), whereas cell clustering (two or three cells) occurs in SW-but not FWacclimated Japanese eel (Anguilla japonica) during early life stages (Sasai et al 1998). Interestingly, in the mangrove killifish, the cell clusters were much larger (20-30 cells).…”

The euryhaline, amphibious mangrove killifish Kryptolebias marmoratus is known to survive weeks out of water in moist environments. We tested the hypothesis that the skin is a site of osmo- and ionoregulation in K. marmoratus. We predicted that under terrestrial conditions, gill and skin remodeling would result in an enhanced role for skin and a diminished role for the gills in osmo- and ionoregulation. Fish were exposed to water-either freshwater (FW, 1‰) or hypersaline water (saltwater [SW], 45‰)-or air over a moist surface of FW or SW for 9 d and then recovered in water. When fish were emersed for 9 d, (22)Na and (3)H-H(2)O were exchanged across the cutaneous surface. Homeostasis of whole-body Cl(-) and water levels but not of Na(+) levels was maintained over 9 d in air. In air-exposed fish, there was a significant increase in the size of skin ionocytes (in SW), a decrease in the number of skin mucous cells (in SW), and an increase in the gill interlamellar cell mass relative to those of fish in water. Gill ionocytes were mostly embedded away from the external surface in air-exposed fish, but the number and size of ionocytes increased (in FW). Interestingly, skin ionocytes formed distinct clusters of 20-30 cells. The estimated number of ionocytes over the whole skin surface was comparable to that in the gills. Overall, the findings support the hypothesis that the skin is a site of osmo- and ionoregulation in K. marmoratus in aquatic and terrestrial environments. Reversible cellular and morphological changes to the skin and gills during air exposure probably enhanced the cutaneous contribution to ion and water balance.

“…28A; Sasai et al 1998;Kaneko et al 2003Kaneko et al , 2008 probably help maintain buoyancy by sustaining osmolalities lower than seawater ). Apparent chloride cells have also been observed in Ariosoma balearicum and Anguilla rostrata leptocephali (Leonard and Summers 1976;Hulet 1978) and in bonefish larvae (Pfeiler and Lindley 1989).…”

“…This is mostly owing to the remarkable advances in the field of fish reproductive endocrinology for the past two decades. Using the eel embryos and larvae obtained from maturation-induced eel, we succeeded in detecting MR cells in the body surface of Japanese eel embryos and larvae, in which the gills were not yet developed (Sasai et al 1998b).…”
