Striking Contrast

The Marine Iguana ( Amblyrhynchus cristatus ) is a species endemic to the Galapagos Islands. It lives in large aggregations along the rocky shore lines throughout the archipelago. It is the only iguanid specialized for feeding on marine algae, which they crop at low tide from the exposed rocks or even by diving down to the bottom of the sea. The animals are extremely gregarious and sometimes hundreds of iguanas bask on the lava rocks in bodily contact with each other. Besides this mutual attraction, however, no specific forms of social interaction like grooming, mutual feeding rituals, etc. are to be observed. This is in striking contrast to the social behaviour of birds and mammals which use such patterns for bond formation. These bond-forming behaviour patterns are mainly derivates of maternal behaviour, which seem to be preadapted for this purpose. Reptiles lack maternal behaviour and this may in part explain their inability to form a closer bond between adults.
