Abstract
250 body temperature measurements were made on 20 humpback whales (Megaptera novae-angliae) from the east coast of Australia, by a series of dorsal-ventral insertions. Inverted temperature profiles were sometimes found indicating the presence of internal masses of cold water. Maximum values were found posteriorly near the umbilicus and the genital opening, and at a depth of 3.3 feet. The average maximum was 36.0[degree]C and there was no correlation with sex, size (33-40 feet) or time of death (0.5-18 hours).
