Roan antelope
Roan antelope are found in woodland and grassland savanna, mainly in the tropical and subtropical grasslands, savannas, and shrublands biome, which range in tree density from forest with a grassy understorey (such as central Zambezian Miombo woodlands) to grasslands dotted with few trees, where they eat midlength grasses. They form harem groups of five to 15 animals with a dominant male. Roan antelope commonly fight among themselves for dominance of their herd, brandishing their horns while both animals are on their knees.
Dactyloidae
A wide range of animals will eat anoles, such as large spiders, centipedes, predatory katydids, snakes, large frogs, lizards, birds, monkeys and carnivoran mammals. At least in part of their range, snakes may be the most significant predator of anoles. For example, the Caribbean "Alsophis" and "Borikenophis" racers, and the Mexican, Central American and South American "Oxybelis" vine snakes feed mostly on lizards like anoles. Some reptile-eating snakes have a specialized venom that has little effect on humans, but it rapidly kills an anole. On some Caribbean Islands anoles make up as much as 40–75% of the diet of American kestrels. Large anoles may eat smaller individuals of other anole species and cannibalism—eating smaller individuals of their own species—is also widespread. There is a documented case of a small anole being captured and killed by an outside potted Venus flytrap plant.
