crocodile

The crocodile gets its name from the Greeks who observed them in the Nile river.
The Greeks called them ‘krokodilos’, a compound word from ‘kroke’, which means pebble, and ‘drilos’, meaning worm.
To the Greeks, this ‘worm of the stones’ was so named because of the crocodiles’ habit of basking in the sun on gravel-covered river banks.
