Lions area unit the sole cats that sleep in teams, that area unit known as prides. Prides area unit family units that will embrace up to a few males, a dozen close to females, and their young. All of a pride's lionesses area unit connected, and feminine cubs generally stick with the cluster as they age. Young males eventually leave and establish their own prides by usurping a bunch headed by another male.
Only male lions boast manes, the spectacular fringe of long hair that encircles their heads. Males defend the pride's territory, which can embrace some a hundred sq. miles (259 sq. kilometers) of grasslands, scrub, or open woodlands. These daunting animals mark the realm with excreta, roar threateningly to warn intruders, and chase off animals that encroach on their turf.
