Abstract
    A temperature-sensitive acoustic transmitter was developed to record and store stomach temperature. The equipment was used to quantify meal sizes in captive animals and to monitor stomach temperature changes in captive animals as a result of intake of food, snow, ice and seawater. The equipment has also been used to time food ingestion in free-ranging animals. The transmitter consists of the electronic circuit, a thermal sensor, an electro-acoustic transducer, a battery and the encapsulation. The time between the transmitter pulses is a function of the surrounding temperature of the transmitter.
