Puzzling Partners

Discover a lizard that uses a scorpion as a bodyguard, a toad that sets up home with a tarantula, an animal that uses hummingbirds as an air charter, the barber that fish use, a crab that carries living fisticuffs, mutant frogs, a snake that acts as pest controller in an owl's nest, dolphins that co-operate with fishermen, a bird that guides people to honey and an odd farmyard full of strange friendships.
