Fig. 1. The mass-specific rate of Na+ secretion via the salt
glands of hatchling leatherback turtles Dermochelys coriacea
(N=12) following an injected salt load of 27 mmol kg-1.
Data points show mean secretion rate ±1 S.E.M.

Fig. 2. The effect of adrenaline (10 µg kg-1 and 1 mg
kg-1) on Na+ secretion rate by the salt glands of
hatchling leatherback turtles Dermochelys coriacea. We stimulated
hatchlings to secrete by injection of 27 mmol NaCl kg-1 and
measured secretory rate before and after injection of adrenaline (N=6
for both groups). Data points show mean secretion rate ±1 S.E.M.

Fig. 3. The effect of methacholine (10 mg kg-1 and 1 mg kg-1)
on Na+ secretion rate by the salt glands of hatchling leatherback
turtles Dermochelys coriacea. We stimulated hatchlings to secrete by
injection of 27 mmol NaCl kg-1 and measured secretory rate before
and after injection of methacholine (N=6 for both groups). Data
points show mean secretion rate ±1 S.E.M.
