The effect of mussel farming on dusky dolphins has been studied in Admiralty Bay. Apparently, dolphins rarely enter farms, and when they do, they quickly swim through them. [55] The building of mussel farms seems to have led to a decline in the number and group size of dolphins passing through the bay and they herded prey less when near the farms.
The common dolphin (Delphinus delphis) is the most abundant cetacean in the world, with a global population of about six million. [3] Despite this fact and its vernacular name, the common dolphin is not thought of as the archetypal dolphin, with that distinction belonging to the bottlenose dolphin due to its popular appearances in aquaria and the media.
Additionally, there was an observation of snubfin dolphins displaying mating courtship between Australian humpback dolphins. [ 12 ] Both the Australian snubfin dolphin and the Australian humpback dolphin co-occur throughout much of the tropical Northern waters of Australia, and have similar vocal repertoires consisting of click trains, burst ...
Pantropical spotted dolphins porpoising. The pantropical spotted dolphin varies significantly in size and coloration throughout its range. The most significant division is between coastal and pelagic varieties. The coastal form is larger and more spotted. (These two forms have been divided into subspecies only in eastern Pacific populations).
The common bottlenose dolphin or Atlantic bottlenose dolphin (Tursiops truncatus) is one of three species of bottlenose dolphin in the genus Tursiops.The common bottlenose dolphin is a very familiar dolphin due to the wide exposure it receives in human care in marine parks and dolphinariums, and in movies and television programs.

Oceanic dolphins or Delphinidae are a widely distributed family of dolphins that live in the sea.Close to forty extant species are recognised. They include several big species whose common names contain "whale" rather than "dolphin", such as the Globicephalinae (round-headed whales, which include the false killer whale and pilot whale).
Aerial view of a pod of Indo-Pacific bottlenose dolphins (Tursiops aduncus) with calves at Gordon's Bay, Sydney. The Indo-Pacific bottlenose dolphin (Tursiops aduncus) is a species of bottlenose dolphin. This dolphin grows to 2.6 m (8.5 ft) long, and weighs up to 230 kg (510 lb). [4]
The false killer whale is in the family Delphinidae (oceanic dolphins). It is in the subfamily Globicephalinae; its closest living relatives are Risso's dolphin, the melon-headed whale (Peponocephala electra), the pygmy killer whale (Feresa attenuata), pilot whales (Globicephala spp.), and possibly snubfin dolphins (Orcaella spp.).
