Interesting about the crocodile

  • Crocodiles are enormously old in geological terms. For almost 200 million years, the appearance of crocodiles has hardly changed. A sign that dinosaurs are perfectly adapted to their environment and can also respond to changes. After all, crocodiles not only lived with, but also survived the dinosaurs.
  • Crocodiles have a stable scale armor.
  • Whether crocodile eggs hatch male or female crocodiles depends entirely on the ambient temperature. In colder temperatures (30 ° C) male.
  • For crocodiles to be able to eat large mammals, they must break their prey into bite-sized pieces. For this they pack the loot and turn around their own axis several times. This role is also called death roll.
  • Crocodiles are patient hunters: for over an hour, a crocodile can wait immobile underwater for prey before it has to catch its breath.
  • The teeth of a crocodile are regularly renewed. If one tooth fails, the next tooth is already waiting underneath.
  • A full-grown crocodile has no natural enemies. Young crocodiles, however, are threatened by fish, monitor lizards, storks and even other crocodiles (cannibalism). Adults only reach between 5 - 10% of young crocodiles.
  • Some crocodile species operate elaborate brood care. The eggs are guarded for weeks by the female. After the first crocodiles hatch, the female carries the brood with her mouth to the water.
  • Crocodiles are hypothermic (poikilotherm) animals. Your body temperature is largely determined by the outside temperature. If it gets too warm, a crocodile just dives under, or opens its mouth. Cold temperatures are potentially less tolerated by crocodiles than warm temperatures.
