Assessment of body surface temperature in cetaceans: an iterative approach
1Departamento de Ciência Animal, Universidade Estadual Paulista, CEP 14884-900, Jaboticabal, SP, Brazil. rgomes@fcav.unesp.br
Abstract:
Heat transfer from skin surface to ambient water is probably the most important aspect of thermal balance in marine mammals, but the respective calculations depend on knowing the surface temperature (Ts), the direct measurement of which in free animals is very difficult. An indirect iterative method is proposed for Ts prediction in free cetaceans from deep body temperature, swimming speed, and temperature and thermodynamic properties of the water.

Equipments Used to Measure Body Temperature
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
