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.

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.

Personally no, not close up, which is odd considering I live in Florida and that dolphins can range from the size of relatively small to the size of a killer whale!

Killer whale
The killer whale or orca ("Orcinus orca") is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and dolphins. They have been known to attack baleen whale calves, and even adult whales. Killer whales are apex predators, as there is no animal that preys on them. Killer whales are considered a cosmopolitan species, and can be found in each of the world's oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas - Killer whales are only absent from the Baltic and Black seas, and some areas of the Arctic Ocean.

The extinct ancestors of modern whales are the Archaeoceti.
Captive killer whales
Killer whales were first captured live and displayed in exhibitions in the 1960s, soon becoming popular attractions at public aquariums and aquatic theme parks due to their intelligence, trainability, striking appearance, playfulness in captivity and sheer size. As of September, 2016, there are 56 orcas in captivity worldwide, 33 of which are captive-born. The practice of keeping killer whales in captivity has become controversial. The killer whale ("Orcinus orca") is the largest species of the Dolphin family. The species is found in all the world's oceans, from the frigid Arctic and Antarctic regions to warm, tropical seas.
Toothed whale
The toothed whales (systematic name Odontoceti) are a parvorder of cetaceans that includes dolphins, porpoises, and all other whales possessing teeth, such as the beaked whales and sperm whales. Seventy-three species of toothed whales (also called odontocetes) are described. They are one of two living groups of cetaceans, the other being the baleen whales (Mysticeti), which have baleen instead of teeth. The two groups are thought to have diverged around 34 million years ago (mya). Toothed whales range in size from the and vaquita to the and sperm whale. Several species of odontocetes exhibit sexual dimorphism, in that the females are larger than males.
Whale
Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. Whales, dolphins and porpoises belong to the order Cetartiodactyla with even-toed ungulates and their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have split apart around 34 million years ago. The whales comprise eight extant families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale), Eschrichtiidae (the grey whale), Monodontidae (belugas and narwhals), Physeteridae (the sperm whale), Kogiidae (the dwarf and pygmy sperm whale), and Ziphiidae (the beaked whales).

What? I had no idea they could get that big. Do you know if they can be aggressive? You always heard about dolphins being friendly.

Dolphins arent known to be aggressive toward humans but they do go after theyre prey! They use conical shaped teeth to catch the fast moving prey!

Tool use by animals
Tools are used by animals for purposes including acquiring food and water, grooming, defense, recreation or construction. Originally thought to be a skill only possessed by humans, some tool use requires a sophisticated level of cognition. There is considerable discussion about the definition of what constitutes a tool and therefore which behaviours can be considered as true examples of tool use. A wide range of animals are considered to use tools including mammals, birds, fish, cephalopods and insects. Primates are well known for using tools for hunting or gathering food and water, cover for rain, and self-defence.
Nile crocodile
The Nile crocodile ("Crocodylus niloticus") is an African crocodile, the largest freshwater predator in Africa, and may be considered the second largest extant reptile in the world, after the saltwater crocodile ("Crocodylus porosus"). The Nile crocodile is quite widespread throughout Sub-Saharan Africa, occurring mostly in the central, eastern, and southern regions of the continent and lives in different types of aquatic environments such as lakes, rivers and marshlands. Although capable of living in saline environments, this species is rarely found in saltwater, but occasionally inhabits deltas and brackish lakes.
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).

Red-tailed hawk
The red-tailed hawk ("Buteo jamaicensis") is a bird of prey that breeds throughout most of North America, from the interior of Alaska and northern Canada to as far south as Panama and the West Indies. It is one of the most common members within the genus of "Buteo" in North America or worldwide. The red-tailed hawk is one of three species colloquially known in the United States as the "chickenhawk," though it rarely preys on standard-sized chickens. The bird is sometimes also referred to as the red-tail for short, when the meaning is clear in context. Red-tailed hawks can acclimate to all the biomes within their range, occurring on the edges of non-ideal habitats such as dense forests and sandy deserts.
Dietary biology of the golden eagle
The golden eagle ("Aquila chrysaetos") is one of the most powerful predators in the avian world. One author described it as "the pre-eminent diurnal predator of medium-sized birds and mammals in open country throughout the Northern Hemisphere". Golden eagles usually hunt during daylight hours, but were recorded hunting from one hour before sunrise to one hour after sunset during the breeding season through their whole range. The hunting success rate of golden eagles was calculated in Idaho, showing that, out of 115 hunting attempts, 20% were successful in procuring prey. A fully-grown golden eagle requires about of food per day.
