アメリカ自然史博物館さんのインスタグラム写真 - (アメリカ自然史博物館Instagram)「It’s National Cat Day! Behold a black cat of epic proportions: this melanistic leopard (Panthera pardus). Also known as “panthers,” leopards can be found across a wide range in Africa and Asia and can reach weights of 198 lbs (90 kg). Individuals like the one pictured are rare in the wild and are affected by a genetic mutation called melanism, which results in their dark coloring. Scientists think there are some advantages that come with having a dusky coat, including being able to more seamlessly blend in with the darkness of the night and take in heat more efficiently in the Sun.
