The dusky dolphin is most closely related to the Pacific white-sided dolphin. [14] The two sister species diverged around 1.9–3.0 million years ago. [15] Hybrids of dusky dolphins have been suggested based on observations and photographic evidence, including with a common dolphin [16] and a southern right whale dolphin. [17]
The bottlenose dolphin is a toothed whale in the genus Tursiops.They are common, cosmopolitan members of the family Delphinidae, the family of oceanic dolphins. [3] Molecular studies show the genus contains three species: the common bottlenose dolphin (Tursiops truncatus), the Indo-Pacific bottlenose dolphin (Tursiops aduncus), and Tamanend's bottlenose dolphin (Tursiops erebennus).
A common bottlenose dolphin (Tursiops truncatus). A dolphin is an aquatic mammal in the clade Odontoceti (toothed whale).Dolphins belong to the families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), Iniidae (the New World river dolphins), Pontoporiidae (the brackish dolphins), and possibly extinct Lipotidae (baiji or Chinese river dolphin).
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.
You can see dolphins about 80-90% of the time on a dolphin sightseeing tour. According to Richardson, the best time to go earlier in the day to see dolphins, because the ocean waves will be calmer.
The key distinguishing feature is the dolphin's coloration—a white to pale-yellow patch is found behind the dorsal fin on both sides of the body. [4] The white-sided dolphin's color variations are unique amongst the standard hues of white, grey, black and blue seen on other pelagic cetaceans. [4]
A spate of dolphin attacks on swimmers in Japan’s Fukui Prefecture is being blamed on one bottlenose dolphin, who researchers believe may be particularly lonely, having been separated from a pod.
