 According to the World Wildlife Fund, the jaguar is already "near threatened" and the loss of food supplies and habitat due to the fires make the situation more critical.The fires affect water chemistry (such as decreasing the amount of dissolved oxygen in the water), temperature, and erosion rates, which in turn affects fish and mammals that depend on fish, such as the giant otter ("Pteronura brasiliensis").The unprecedented fires of the 2019–20 Australian bushfire season that have swept through 18 million acres (7 million hectares) have claimed 29 lives and have stressed Australia's wildlife.
