When animals meet each other for the first time, it can go one of two ways. We hope they’d hit it off and become friends, but sometimes, they become enemies. This photograph captures invasive coyotes and wolves. They’re meeting for the first time at Yellowstone. Coyotes (Canis latrans) and wolves (Canis lupus) are closely related species of carnivorous mammals, but there are several key differences between them. Coyotes are generally smaller than wolves, with adult coyotes weighing between 9 and 20 kg (20 and 44 lbs) and adult wolves weighing between 23 and 41 kg (50 and 90 lbs). From this photograph, we can’t tell if they’re friends or foes. Let’s hope they’re friends (via Bored Panda).
