My favorite mammal is a dolphin! There are so many kinds of dolphins that are widely distributed around the world!

Dolphin
Dolphins are a widely distributed and diverse group of aquatic mammals. They are an informal grouping within the order Cetacea, excluding whales and porpoises, so to zoologists the grouping is paraphyletic. The dolphins comprise the extant families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), Iniidae (the new world river dolphins), and Pontoporiidae (the brackish dolphins), and the extinct Lipotidae (baiji or Chinese river dolphin). There are 40 extant species of dolphins. Dolphins, alongside other cetaceans, belong to the clade Cetartiodactyla with even-toed ungulates.
Oceanic dolphin
Oceanic dolphins or Delphinidae are a widely distributed family of dolphins that live in the sea. Thirty extant species are described. They include several big species whose common names contain "whale" rather than "dolphin", such as the killer whale and the pilot whales. Delphinidae is a family within the superfamily Delphinoidea, which also includes the porpoises (Phocoenidae) and the Monodontidae (beluga whale and narwhal). River dolphins are relatives of the Delphinoidea. Oceanic dolphins range in size from the -long and Maui's dolphin to the and killer whale, the largest known dolphin. Several species exhibit sexual dimorphism; the males are larger than females.
Cetacea
Cetacea () are a widely distributed and diverse clade of aquatic mammals that today consists of the whales, dolphins, and porpoises. Cetaceans are carnivorous and finned. Most species live in the sea, some in rivers. The name is derived from the Latin "cetus" "whale", itself from the Greek κῆτος "kētos" "huge fish". There are around 89 extant species, which are divided into two groups or parvorders, the Odontoceti or toothed whales, a group of more than 70 species that includes the dolphins and porpoises, and the Mysticeti or baleen whales, of which there are now 15 species. The extinct ancestors of modern whales are the Archaeoceti.
Bottlenose dolphin
Bottlenose dolphins, the genus Tursiops, are the most common members of the family Delphinidae, the family of oceanic dolphin. Molecular studies show the genus contains three species: the common bottlenose dolphin ("Tursiops truncatus"), the Indo-Pacific bottlenose dolphin ("Tursiops aduncus"), and the Burrunan dolphin ("Tursiops australis"). Bottlenose dolphins inhabit warm and temperate seas worldwide, being found everywhere except for the Arctic and Antarctic Circle regions. Bottlenose dolphins live in groups typically of 10–30 members, called pods, but group size varies from single individuals up to more than 1,000.
Marine mammal
Marine mammals are aquatic mammals that rely on the ocean and other marine ecosystems for their existence. They include animals such as seals, whales, manatees, sea otters and polar bears. They do not represent a distinct taxon or systematic grouping, but rather have a polyphyletic relation due to convergent evolution, as in they do not have an immediate common ancestor. They are also unified by their reliance on the marine environment for feeding. Marine mammal adaptation to an aquatic lifestyle varies considerably between species. Both cetaceans and sirenians are fully aquatic and therefore are obligate water dwellers.
River dolphin
River dolphins are a very widespread group of fully aquatic mammals that reside exclusively in freshwater or brackish water. They are an informal grouping of dolphins, which is a paraphyletic group within the infraorder Cetacea. The river dolphins comprise the extant families Platanistidae (the Indian dolphins), Iniidae (the Amazonian dolphins), and Pontoporiidae (the brackish dolphins). There are five extant species of river dolphins, and two subspecies. River dolphins, alongside other cetaceans, belong to the clade Cetartiodactyla, with even-toed ungulates, and their closest living relatives the hippopotamuses, having diverged about 40 million years ago.
Cetacean intelligence
Cetacean intelligence refers to the cognitive capabilities of the Cetacea order of mammals. This order includes whales, porpoises, and dolphins. Brain size was previously considered a major indicator of the intelligence of an animal. However, many other factors also affect intelligence. Recent discoveries concerning bird intelligence have called into question the usefulness of brain size as an indicator. Since most of the brain is used for maintaining bodily functions, greater ratios of brain to body mass may increase the amount of brain mass available for more complex cognitive tasks. Allometric analysis indicates that mammalian brain size scales at approximately the ⅔ or ¾ exponent of the body mass.

Fun! I once seen a pack of porpoises while boating. I think they're in the same family as dolphins?

Yes they are! There are actually 40 species of dolphins to be exact!

Carbovaris
Carbovaris were a short-lived Hungarian indie rock band based in Budapest, Hungary formed in 2009. The band consisted of members Ármin Jamak (vocals), Dániel Nyitray (bass), Soma Balázs (guitars), Zsombor Lehoczky (drums). In 2012 the band's first LP was released entitled Milos. In 2013, the band was nominated as the best new act in Hungary by the Viva TV. On 6 December 2013, Carbovaris released two singles, "Sand & Dust" and "Automatic/Pragmatic", from their forthcoming album. On 12 December 2013, Carbovaris played at the A38 in Budapest, Hungary. The show was available on stream. Carbovaris played their last show at the Gozsdu Manó Klub in Budapest on 31 January 2014.
Miami Dolphins
The Miami Dolphins are a professional American football franchise based in the Miami metropolitan area. The Dolphins compete in the National Football League (NFL) as a member club of the league's American Football Conference (AFC) East division. The Dolphins play their home games at Hard Rock Stadium in the northern suburb of Miami Gardens, Florida, and are headquartered in Davie, Florida. The Dolphins are Florida's oldest professional sports team. Of the four AFC East teams, they are the only team in the division that was not a charter member of the American Football League (AFL). The Dolphins team was founded by attorney-politician Joe Robbie and actor-comedian Danny Thomas.

The Dolphins team was founded by attorney-politician Joe Robbie and actor-comedian Danny Thomas. They began play in the AFL in 1966. The region had not had a professional football team since the days of the Miami Seahawks, who played in the All-America Football Conference in 1946 before becoming the first incarnation of the Baltimore Colts. The first professional American football team to be based in Miami and the state of Florida was the Miami Seahawks.
