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.
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).
As with other oceanic dolphins, dusky dolphins produce three basic sounds; echolocative click trains, burst pulses and tonal whistles. [ 39 ] [ 40 ] : 77 Their echolocation signals are quick and broadband , much like in other whistle-producing species, [ 40 ] : 95 and have two peaks; between 40 and 50 kHz at low frequency and between 80 and 110 ...
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).
Anthropogenic activities, such as cetacean-based tourism [20] or recreational boating, [22] can impact dolphins through physical presence, non-compliance to regulations and acoustic disturbance. Such disturbances can negatively affect the long-term viability of small resident populations, summarised in Puszka et al. 2021.

[1] The genre of a particular Bible passage is ordinarily identified by analysis of its general writing style, tone, form, structure, literary technique, content, design, and related linguistic factors; texts that exhibit a common set of literary features (very often in keeping with the writing styles of the ...
Clymene dolphins spend most of their lives in waters over 100 m (330 ft) in depth, but occasionally move into shallower, coastal regions. [12] They feed on squid and small schooling fish, [ 7 ] [ 13 ] hunting either at night, or in mesopelagic waters where there is only limited light.
