title: [Ecological adaptation of the lizzardCryptoblepharus boutoni cognatus (boettger) for life in the interditel zone (reptilia, skinkidae)].
abstract: The lizardCryptoblepharus boutoni cognatus was observed in Madagaskar. The animals descended daily into the intertidal zone to feed there on insects, crustaceans and fish (juvenilePeriophthalmus kohlreuteri). The pattern of activity of the animals is related to the movements of the tides.The lizards have a definite home range and migrate between intertidal feeding area and resting place on land along pathways established by experience. They return to their home even if released at about 200 m from their home range because they seem to acquire a knowledge of the surrounding by occasional exploratory visits. The tendency to establish a home range and homing behaviour are considered as adaptations for life in the intertidal zone, but the lizard remains a purely terrestial animal.
