The feeding behavior of consuming dead organic matter, particularly the remains of animals that have died from causes other than predation by the scavenger. This behavior plays a crucial role in nutrient cycling.
From Middle English 'scavager,' originally referring to a person who cleaned streets. The ecological meaning developed in the 19th century as naturalists studied the roles of different animals in ecosystems.
Scavengers are nature's clean-up crew, preventing disease outbreaks by rapidly disposing of carcasses - vultures have stomach acid so strong it can neutralize anthrax and cholera! Without scavengers, dead animals would pile up and create serious health hazards for entire ecosystems.
