Normally you try to catch a croc by throwing a sort of a small anchor in and when the croc latches on to it you try and pull it out.

We would jump into the pits with big sticks and chase all the crocs into the water.

I could feel the crocs at my feet through the iron mesh that I held grimly onto.

(That's the only way to prevent a croc from getting back into water!).

This would effectively push the crocs from the deep water onto the land.

But workers can sometimes make mistakes while sexing small crocs.
