Periods of no activity between 02.00 and 10.00 and lasting for up to 7 h 40 min are reported for two captive Crocidura flavescens (I. Geoffroy, 1827). During one of these periods, the weight specific energy requirement of the shrew dropped to 25.1% of the usual, indicating a period of spontaneous torpor. Nest-box temperatures also drop during the periods of prolonged inactivity suggesting a lowered body temperature. Data for a younger animal suggest shorter periods of torpor. The timing of the torpor spans the coldest period of the day when the animal would expend most energy maintaining a constant body temperature.
