Despite having a relatively small brain for their body size (about the size of a walnut), estuarine crocodiles are intelligent creatures capable of complex behaviours such as
advanced parental care, communication, and teamwork when hunting. They can even put half of their brain to sleep while the other half stays awake to watch for prey and threats.
