Knowra Bottlenose dolphin Bottlenose dolphin A large oceanic dolphin in the genus Tursiops, recognized by its robust body and short, beaklike snout. It lives in coastal and offshore waters worldwide.
Cetacea : An order of aquatic mammals comprising whales, dolphins, and porpoises. Bottlenose dolphins are toothed cetaceans adapted to life in water.
Dolphin biosonar : The sound-based sensing system dolphins use to locate and identify objects underwater. This is the specialized form of echolocation used by bottlenose dolphins.
Shark Bay bottlenose dolphins : A population of bottlenose dolphins in Shark Bay, Western Australia, known for diverse foraging traditions. Some use marine sponges as tools to protect their snouts while searching the seafloor.
Bycatch : The incidental capture of non-target animals during fishing. Fishing gear can entangle and kill bottlenose dolphins.
Toothed whale : A cetacean in the suborder Odontoceti, which includes dolphins, porpoises, and sperm whales. The bottlenose dolphin belongs to this group, defined by teeth and echolocation.
Melon (cetacean anatomy) : A fatty organ in the forehead of toothed whales that helps focus outgoing sound. It shapes the clicks bottlenose dolphins send through the water.
Dolphin-assisted fishing in Laguna : A cooperative fishery in Laguna, Brazil, where dolphins signal fishers when to cast nets. It documents coordinated hunting between local bottlenose dolphins and people.
Marine noise pollution : Human-generated underwater sound that alters or disrupts marine acoustic environments. Noise can mask dolphin signals and interfere with echolocation.
Echolocation : A biological or technological process that uses echoes of emitted sounds to locate objects. Bottlenose dolphins use returning clicks to detect prey and navigate.
Dolphin auditory system : The structures and processes by which dolphins receive and interpret sound. Echoes reach the inner ear through the lower jaw and surrounding tissues.
