To date, PODs have been shown to detect the species listed below. Please click on the links below for information on each species. Atlantic white-sided dolphin, Lagenorhynchus acutus Australian snubfin dolphin, Orcaella heinsohni Burmeister's dolphin, Phocoena spinipinnis Cuvier's beaked whale, Ziphius cavirostris Beluga, Delphinapterus leucas Boto, Inia geoffrensis Bottlenose dolphin, Tursiops truncatus and Tursiops aduncus Commerson's dolphin, Cephalorhynchus commersonii Common dolphin, Delphinus delphis Harbour porpoise, Phocoena phocoena Heaviside's dolphin, Cephalorhynchus heavisidii Indo-Pacific humpback dolphin, Sousa chinensis Long-finned pilot whale, Globicephala melas Maui dolphin, Cephalorhynchus hectori maui (subspecies of Hector's dolphin) Orca, Orcinus orca Peale's dolphin, Lagenorhynchus australis Risso's dolphin, Grampus griseus Short-finned pilot whale, Globicephala macrorhynchus Susu, Platanista gangetica Tucuxi, Sotalia fluviatilis Vaquita, Phocoena sinus In quiet locations, over 40% of clicks identified in porpoise monitoring occur as click trains. Similar rates can be found from dolphins in such quiet locations as the Amazon. More typically, in dolphin monitoring, less than 5% of the clicks are in trains. This is because their clicks are less distinctive, so more non-cetacean clicks are logged at the maximum bandwidth required to include the cetacean clicks and because more echoes and multi-path duplicates of clicks are received from these louder animals. Sperm whales, Physeter catodon may be difficult to monitor, although monitoring has not yet been tried.
