Different crocodilian behaviours have been categorised on the basis of their primary function - maintenance, social interactions and reproduction.
- Maintenance behaviours include daily activities associated with thermoregulation and osmoregulation (movements between water and land, sun and shade), predator avoidance and feeding.
- Social behaviours involve communication between individuals of the same species, which is achieved using visual, tactile, vocal and chemical signals.
- Reproductive behaviours are those associated with courtship, mating, nesting and post-hatching care.
