Common eland

Cow-like bulk is the first clue: this and the rarer giant eland are the two largest antelope on Earth, close enough in size that accounts differ, though the giant eland is usually ranked first, and bulls can top 2,000 pounds. Both sexes carry nearly straight horns with tight spiral twists, a female's longer and thinner than a male's. A loose dewlap hangs from the throat, tufted with black hair in males, and the tan coat may show thin white stripes on the flanks. Coats gray with age, so old bulls can look almost blue-black. Eland live in grassland, acacia savanna, mountain and miombo woodland across eastern and southern Africa, avoiding desert, forest and swamp. For all that weight, they clear a 5-foot barrier with ease.
