Interesting capabilities of Crocodiles

• they can hold their breath underwater for up to one and a half hours

• their brain is only the size of a walnut but it still allows enough 'processing' to take place to enable the animal to make a decision about whether to attack or not

• crocs replace their teeth by growing new ones inside old ones which eventually fall out

• the stomach of the crocodile is only about the size of a basketball and contrary to legends and 'old wives' tales', crocs do not store their food - they eat it right away
