Why do Australian crocodiles have maggots in their mouth?

Australian crocodiles often have maggots in their mouths due to a symbiotic relationship with certain species of flies. These flies lay their eggs in the crocodile's open wounds, and when the eggs hatch, the maggots feed on dead tissue, helping to clean the wounds. This natural process aids in the crocodile's healing while providing a safe environment for the maggots to grow. Additionally, the presence of maggots can help prevent infection, benefiting the crocodile overall.
