Of Iguanas and Dinosaurs: Social Behavior and Communication in Neonate Reptiles

Abstract

Newborn and newly hatched reptiles show diverse types of social behavior. Aggregation behavior in snakes, dominance in turtles, vocalization in crocodilians, and synchronized nest emergence, migration, and foraging behavior in iguanas are documented. Such evidence casts doubt on inferences about a generalized reptilian level of social organization qualitatively inferior to that found in birds and mammals.
