How do sea lions use vocalizations for communication?

Sea lions use vocalizations to communicate with other members of their colonies, especially in noisy environments like rookeries. They produce a variety of sounds, including barks, growls, and roars, to establish territory, warn others of danger, or attract mates. These vocalizations can carry over long distances, helping sea lions communicate during mating season or when they need to locate other individuals. Vocalizations also help maintain social structure within the group, ensuring effective cooperation.
