Information concerning body temperature was recorded by radio transmission from within a dolphin, Tursiops truncatus, swimming freely in a pool. The temperature varied according to the activity of the animal and appeared to oscillate when the dolphin was returned to the pool after a brief period outside it. The transmitter was passed approximately 17 hours after it had been swallowed. A new type of antenna was used with the circuit. The transmitter can be adapted for telemetering heart beat, movement, aquatic animals.
通过无线电传输记录了一只宽吻海豚（Tursiops truncatus）在水池中自由游动时的体温信息。体温随动物的活动而变化，并且当海豚在池外短暂停留后回到池中时，体温似乎会出现波动。发射器在被吞下约17小时后排出体外。该电路使用了一种新型天线。该发射器可适用于遥测水生动物的心跳、运动情况。
