Crocodiles

A crocodile is poikilothermic, that’s how crocodiles are:
without an external source of heat a crocodile won’t get far.

Your temperature is ninety eight point four in Fahrenheit
But for a crocodilian, no one number is right

They’re colder when it’s colder out, they’re hotter when it’s hot
But test it with a thermometer ? My advice is – better not.
