| Abstract |
1. Emphasis is placed upon the need for in situ observations on marine animals when designing actographs for laboratory recording of locomotor rhythmicity and when interpreting the adaptive value of such rhythmicity.2. Two burrowing decapods, Goneplax rhomboides and Nephrops norvegicus, show highly persistent circadian rhythms when kept in actographs incorporating simulated burrows.3. In some other crustaceans interactions between individuals affect the period and amplitude of the spontaneous locomotor rhythm.4. The significance of very persistent rhythms in burrowing species is discussed. |
