Resumen
Se presentan por primera vez para Colombia valores de consumo de oxígeno para Lytechinus variegatus en un ciclo de 24 horas. No se confirmó la expectativa de un ritmo circadiano de actividad reflejado en cambios del consumo de oxígeno. El posible papel ecotrófico de L. variegatus se revisa y discute brevemente.
