SUMMARY
Some Electrolytes, Hormones and
other Substances in the Blood of
Fin Whales of the Coast of Iceland

Several electrolytes (Na, Cl, K, Ca),
creatinine, urea, uric acid, total protein,
cholestrol, triglycerides, cortisol and al-
dosterone were measured in the serum of
fin whales which had been caught off the
coast of Iceland. Blood samples were tak-
en postmortem from a fluke vessel at sea,
immediately after the animal had been
brought alongside the ship. Measurements
for Na, K, Cl, urea, pH and osmolality
were also done on urine apsirated from
the bladder at the whaling station.
The mean serum electrolyte (Na, K, CI)
levels were found to be a little higher than
those in terrestrial mammals. Serum calci-
um, creatinine and protein levels were
similar, while those of urea and uric acid
in the whales were 6 times higher and 20
times lower respectively tlian in terrestrial
mammals. Cholesterol levels were similar
and triglyceride levels 2-3 times higher
than those of a fasting man.
Serum cortisol levels were 15 times low-
