Temperature regulation in the Amazonian manatee Trichechus inunguis.

–Summ.: New Scientist, Dec. 1, 1983: 654, 1 fig. Core temperatures of two animals were measured (with swallowed transmitters) at 35-36 C and varied with water temperature within the thermoneutral zone; below that zone (i.e., below 22-23 C) they were maintained, primarily by increase in activity. Their primary mechanism for thermoregulation seemed to be changes in peripheral circulation, aided by subcutaneous fat insulation. Speculates that cold-related mortality and limits to distribution in T. manatus may be due less to physiology than to nutritional status and food availability.
