Orcas on the hunt, penguins and right whales protecting their young, foxes patrolling the beaches - Argentina's Atlantic coastline is as dynamic as it is dangerous.

A mechanic spots an enormous black mamba disappear into a scrapheap, and Simon and Sioux pick up their new apprentice before putting her snake skills to the test.

After a hair-raising rescue of a super-fast black mamba, the team gets a call from a wildlife rescue expert with a troublesome crocodile on his hands.
