African penguins face repeated catastrophic oil spills that coat feathers, impair thermoregulation, cause toxic ingestion, and require intensive rehabilitation - making them one of the most oil-vulnerable seabird species.
Oil spills cause acute suffering across all biological systems: hypothermia from loss of waterproofing, starvation from inability to dive and fish, and internal organ damage from toxin ingestion. Rehabilitation itself involves repeated handling stress for wild animals. However, without treatment, oiled penguins face near-certain death. The existence of dedicated rehabilitation centers in South Africa demonstrates what organized response can achieve for individual animals.
