RESEARCH with deep burrowing species, such as Lumbricus terrestris (the lob worm), demonstrates that during a 24-hour period, activity is greatest from dusk until dawn. This is not surprising, as these creatures possess photo-receptive cells (even though they have no eyes) and therefore only surface to feed and mate under cover of darkness. During less active periods of the day, their oxygen consumption has been shown to be at its lowest, but only physiological experiments could determine the level of nervous activity at these times. During adverse soil conditions, such as drought, certain species (there are 28 different types of earthworm in the UK) enter a dormant state known as dispause. Within the soil the earthworms form a mucus-lined chamber, in which they curl into a tight ball in order to prevent moisture loss. They remain in these chambers until more favourable soil conditions prevail. If earthworms do 'sleep', it must be during such times when all other behaviours cease.
