Sea turtles live in a medium that is almost three times more concentrated than their body
fluids, some ions having even greater plasma/sea water gradients (ie, 23-fold for Mg^+ …

Sea turtles can regulate levels of the majority of the solutes (the monovalent ions) in their
body fluids via the secretions of the post-orbital salt glands. The concentration of these …

We measured the salt and water balance of hatchling leatherback sea turtles, Dermochelys
coriacea, during their first few days of life to investigate how they maintain homeostasis …

The painted turtle, Chrysemys picta belli, loses sodium, calcium and potassium ions to its
freshwater environment. Absorption of sodium and calcium but not potassium from …

1. Plasma ion (Na+, K+, Cl−, HCO− 3, lactate, Ca, and Mg) concentrations were measured
during apneic submergence in aerated water at 10° C of 4 species of freshwater turtles …

The efflux of sodium ions from the loggerhead turtle, Caretta caretta, was investigated when
animals were acclimated to seawater, freshwater, and during the acclimation period after …

When salt-gland-cannulated green sea turtles were stimulated by the intravenous injection
of various salt loads the secretion osmolality rose quickly from a basal value of 300–400 …

Sodium balance in the green turtle, Chelonia mydas, has been investigated in both
seawater and freshwater. In seawater the unidirectional Na efflux is 131 μM· 100 g− 1· h− 1 …

Fresh‐water softshell turtles (Trionyx spinifer) showed net uptake of sodium from solutions
as dilute as 5 m̈M. Chloride uptake could be accounted for by passive processes. There …

Freshwater biota experience physiological challenges in regions affected by salinization, but
often the effects on particular species are poorly understood. Freshwater turtles are of …
