Dusky dolphinThe dusky dolphin (Lagenorhynchus obscurus) is a dolphin found in coastal waters in the Southern Hemisphere. Its specific epithet is Latin for "dark" or "dim". It is very closely genetically related to the Pacific white-sided dolphin, but current scientific consensus holds they are distinct species. The dolphin's range is patchy, with major populations around South America, southwestern Africa, New Zealand, and various oceanic islands, with some sightings around southern Australia and Tasmania.
Animal echolocationEcholocation, also called bio sonar, is a biological sonar used by several animal species. Echolocating animals emit calls out to the environment and listen to the echoes of those calls that return from various objects near them. They use these echoes to locate and identify the objects. Echolocation is used for navigation, foraging, and hunting in various environments. Echolocating animals include mammals, most notably Laurasiatheria, especially odontocetes (toothed whales) and some bat species, and also, using simpler forms, species in other groups such as shrews.
SeaWorld San DiegoSeaWorld San Diego is a theme park located in Mission Bay Park, San Diego, California, United States. Owned and operated by SeaWorld Parks & Entertainment, the park is multifaceted, animal-focused marine mammal park, oceanarium, and aquarium—with both indoor and outdoor aquatic exhibits. Behind-the-scenes, SeaWorld San Diego is also a noted marine animal rehabilitation center. The park's shared waters of Mission Bay connect directly to the Pacific Ocean, and it is this seaside location—and accessibility by boat—which enables the rescuing, rehabilitating and (when possible) re-releasing of injured, orphaned or stranded marine animals.
Irrawaddy dolphinThe Irrawaddy dolphin (Orcaella brevirostris) is a euryhaline species of oceanic dolphin found in scattered subpopulations near sea coasts and in estuaries and rivers in parts of the Bay of Bengal and Southeast Asia. It closely resembles the Australian snubfin dolphin (of the same genus, Orcaella), which was not described as a separate species until 2005. It has a slate blue to a slate gray color. Although found in much of the riverine and marine zones of South and Southeast Asia, the only concentrated lagoon populations are found in Chilika Lake in Odisha, India and Songkhla Lake in southern Thailand.
