A number of species of euryhaline teleosts have the remarkable ability to adapt and survive
in environments of extreme salinity, up to two or even three times the osmolality of seawater …

We examined the involvement of mitochondria-rich (MR) cells in ion uptake through gill
epithelia in freshwater-adapted killifish Fundulus heteroclitus, by morphological observation …

Teleost fishes, living in fresh water, engage in active ion uptake to maintain ion homeostasis.
Current models for NaCl uptake involve Na+ uptake via an apical amiloride-sensitive …

August Krogh proposed that freshwater fishes (and other freshwater animals) maintain body
NaCl homoeostasis by extracting these ions from the environment via separate Na+/NH4+ …

The ability to reverse the net direction of gill ion transport in response to a salinity change is
critical for euryhaline teleosts and involves a complex cellular and molecular remodelling of …

Maintenance of ion balance requires that ionoregulatory epithelia modulate ion flux in
response to internal or environmental osmotic challenges. We have explored the basis of …

This review summarizes the mechanism of Cl− active secretion and its regulation in
estuarine teleost fish. Small estuarine fish such as the killifish, Fundulus heteroclitus, forage …

The common killifish, Fundulus heteroclitus, is a euryhaline teleost common throughout
estuaries of eastern North America. This symposium paper reviews the important …

The objective of this study is to test the hypothesis that morphologically different
mitochondria-rich (MR) cells may be responsible for the uptake of different ions in freshwater …

The crustacean gill is a multi-functional organ, and it is the site of a number of physiological
processes, including ion transport, which is the basis for hemolymph osmoregulation; acid …
