The family "Phalacrocoracidae," commonly known as cormorants and shags, includes aquatic birds found worldwide, primarily near coastal and freshwater habitats. These birds are characterized by their long necks, webbed feet, and a distinctive hooked bill, which aids in catching fish. Cormorants are excellent divers, often seen swimming with only their heads above water. Cormorants typically have dark plumage, which can vary among species. They are social birds, often nesting in colonies and displaying cooperative hunting behaviors. Their unique ability to dive deep for fish makes them important players in aquatic ecosystems, helping to maintain fish populations and overall biodiversity.
