Abstract
ARGININE or lysine vasopressin is found in the pituitaries of most placental mammals and arginine vasopressin has been tentatively identified in a monotreme1 and in four species of marsupials1,2. We have investigated antidiuretic activity in the pituitary of a young koala bear (Phascolarctos cinereus), which is of interest because this animal is rarely, if ever, known to drink, its water intake being derived solely from eucalyptus leaves.
