Banc d'Arguin National Park as grey heron ("Ardea cinerea monicae") and Eurasian spoonbill ("Platalea leucorodia balsaci") and western reef heron ("Egretta gularis") (IUCN, 1987). For marine mammals, endangered species can be seen here all-year round; for example, Mediterranean monk seals, Atlantic humpback dolphins and bottlenose dolphins. Other species can be seen here are orca, the killer whales, pilot whales, Risso's dolphins, dolphins (common, rough-toothed). Fin whales and harbor porpoises are also known to visit the area. Possibly, highly coastal whale species such as North Atlantic right whales, now-extinct Atlantic gray whales were used to be seen here as well. Other baleen whales possibly occur
Toothed belt slippage, and are often used to transfer motion for indexing or timing purposes (hence their name). They are often used in lieu of chains or gears, so there is less noise and a lubrication bath is not necessary. Toothed belts are used widely in mechanical devices, including sewing machines, photocopiers and many others. A major use of toothed belts is as the timing belt used to drive the camshafts within an automobile or motorcycle engine. As toothed belts can deliver more power than a friction-drive belt, they are used for high-power transmissions. These include the primary drive of some motorcycles,
