The fellow has insufficient understanding of the crocodile.
The main reason that I wear purple tights is that it is known as the colour that is restful and calming to the crocodile. In all my jungle adventures I have NEVER had my arm mauled in that fashion, despite me routinely wrestling crocodiles, swimming with crocodiles, running along the back of crocodiles and even helping old crocodiles across the road & river.
Why? Purple is pacifying.
There's an old jungle saying ...
"Man who wears blue will be bitten in two"
