Knowra Odontoceti Odontoceti Odontoceti is the cetacean suborder of toothed whales, including dolphins, porpoises, sperm whales, beaked whales, and river dolphins. Its members generally use echolocation to detect prey and navigate underwater.
Cetacea : Cetacea is the mammalian order comprising whales, dolphins, and porpoises. Odontoceti is one of the two living branches of this order.
Phonic lips : Phonic lips are paired nasal structures that generate high-frequency clicks in toothed whales. They produce the clicks odontocetes use for echolocation.
Sperm whale : The sperm whale is the largest living toothed whale, known for deep dives and a massive head. It is the largest-bodied member of Odontoceti.
Cetacean evolution : Cetacean evolution is the transition and diversification of mammals from land-dwelling ancestors into fully aquatic whales. Odontoceti arose during the cetacean transition to aquatic life.
Bycatch : Bycatch is the unintended capture of non-target animals during fishing operations. Fishing gear, especially gillnets, kills porpoises and other odontocetes.
Mysticeti : Mysticeti is the cetacean suborder of baleen whales, which filter-feed using baleen plates. Mysticeti is the other living cetacean suborder, distinguished by baleen instead of teeth.
Toothed whale biosonar : Toothed whale biosonar is the production, transmission, reception, and interpretation of echolocation signals. It describes the sensory process shared by many odontocete species.
Beaked whale : Beaked whales are a family of deep-diving toothed whales, many with elongated beaks and few visible teeth. Their specialized deep dives and elusive behavior distinguish a major odontocete lineage.
Archaeoceti : Archaeoceti is an extinct group of early whales that lived during cetaceans' transition from land to water. These early whales precede the split between living toothed and baleen whales.
Underwater noise : Underwater noise is human-produced or natural sound that propagates through aquatic environments. Noise can interfere with odontocete communication, navigation, and echolocation.
