The Common Bottlenose Dolphin or Atlantic Bottlenose Dolphin (Tursiops truncatus) is a wide-ranging marine mammal of the family Delphinidae.
The name is originally from Greek δελφίς (delphís), "dolphin", which was related to the Greek δελφύς (delphus), "womb". The animal's name can therefore be interpreted as meaning "a 'fish' with a womb". The name was transmitted via the Latin delphinus (the romanization of the later Greek δελφῖνος – delphinos), which in Medieval Latin became dolfinus and in Old French daulphin, which reintroduced the ph into the word "Dolphin". The term mereswine (that is, "sea pig") has also historically been used.
Singular: dolphin
Plural: dolphins
Common bottlenose dolphins are gray and white underneath in color and range between 2 and 4 m, long wave-like raise fin, moderate wave-like flippers, and a tailfin.
Common bottlenose dolphins are closely related to other Tursiops dolphins, including the Indo-Pacific bottlenose dolphin (Tursiops aduncus), and belong to the oceanic dolphin family Delphinidae. This species is related to false killer whales, spinner dolphins, and spotted dolphins, among other delphinids. Around 5–20 million years ago, during the Miocene, when contemporary dolphin lineages began to diversify, fossil relatives first appeared.
High intelligence is exhibited by common bottlenose dolphins, who can solve problems, recognize themselves, use tools (such as carrying a sponge), and communicate in sophisticated ways. They are able to hold their breath for five to twelve minutes. These dolphins have a 4- to 6-meter leap, which they employ for communication and possibly to get rid of parasites. Common bottlenose dolphins are capable of swimming at speeds of 5 to 12 km/h, with bursts of up to 30 to 35 km/h. They use flippers for precision steering and strong up-and-down tail strokes.
The main sonar method used by dolphins to find prey is echolocation. Dolphins also communicate by making noises, such as squeaks from the blowhole, whistles from the nasal sacs beneath the blowhole, and noises from body language, like jumping out of the water and slapping their tails on the water. They have an oily coating on their heads that protects the braincase and serves as an acoustic lens. To ascertain the position and form of objects in the vicinity, including possible prey, they make clicking noises and listen for the return echoes.
Although they can perish from dehydration outside of water, dolphins breathe air just like all other mammals and do not suffocate. Disease, biotoxins, pollution, habitat alteration, including freshwater incursions, vessel strikes, human feeding, harassment-causing activities, interactions with commercial and recreational fishing, energy exploration, oil spills, and other human disturbances, like underwater noise, are just a few of the many stressors and threats that they face.
Dolphins have few marine enemies. Some species or specific populations have none, making them apex predators. Because the magnitude of threats may differ among tributaries, extrapolation from these small study areas should be undertaken with caution. The tucuxi exists in small groups of about 10-15 individuals, and swim in tight-knit groups, suggesting a highly developed social structure. Tucuxis are quite active and may jump clear of the water (a behavior known as breaching), somersault, spy-hop or tail-splash.
Common bottlenose dolphins and other dolphins are thought to be some of the smartest animals on the planet, challenging the great apes (chimps and gorillas) for the top spot. They are also extremely curious and often approach people to investigate. Their intelligence is likely both a result of and a driver of their complex social structures. Its diet consists mainly of eels, squid, shrimp and a wide variety of fishes.
Mating: Polygamous; males may form alliances to court females.
Gestation: ~12 months.
Calves: 1 offspring, ~1.0–1.3 m at birth; nurses for 18–20 months; stays with mother for 3–6 years.
Sexual maturity: Females ~5–13 years; males ~8–15 years.
Lifespan: Typically 20–40 years; some exceed 50.
The common bottlenose dolphin is a highly gregarious species that lives in groups called pods, which usually consist of 15 individuals. However, pod sizes can range from pairs of dolphins to over 100 or even 1,000 animals for brief periods of time. These group categories include groups of adult males, juvenile groups, and nursery groups. The dolphin may remain submerged until it drowns if it is unable to locate a way to retrieve an object that has been dropped. Like other gregarious animals, if the survivor or another creature strikes a dolphin, the entire pod retaliates and attacks all at once.
Bycatch: Entanglement in fishing gear is a major threat.
Pollution: Heavy metals, PCBs, plastics, noise pollution.
Habitat degradation: Coastal development and boat traffic.
Hunting: Rare today but still occurs in some regions.
Climate change: Alters prey availability and ocean conditions.
IUCN Red List: Least Concern (LC)

Common bottlenose dolphins (referred to hereafter simply as bottlenose dolphins) are found throughout the world in both offshore and coastal waters, including harbors, bays, gulfs, and estuaries of temperate and tropical waters (estuaries are the areas where rivers meet the sea). Population trends for common bottlenose dolphins are not well known, but scientists believe this dolphin to be a species of least concern.
During The Recollections of Queen Arianna (TROQA) saga in the 2600s and 2700s, the "Sky People," or Terrans from Earth, brought the common bottlenose dolphin to two exoplanets that resembled Earth: Reinachos from Cygnus and Berbania from Ursa Major. Despite the death of our planet, conservation efforts are helping this species recover from endangerment or near extinction. The bottlenose dolphin became an invasive species as a result of human interactions for game hunting and rewilding. In two exoplanets that resembled Earth, the bottlenose dolphin lived in conditions and climates identical to those of Earth.

You cannot tame most dolphin species, except for common dolphin, orca, tucuxi, spotted dolphin, Commerson's dolphin, and bottlenose dolphin. Dolphins can be fed raw cod or pulled along with a lead that are tamed non-violently, rather than through a cordial and curious creature, it will slowly approach any survivor that is within radius. To tame it, you need to pet the creature twice, then feed it with fish or lobster meat.
In our universe, common bottlenose dolphins are not appropriate pets. Large size and high intelligence necessitate specialized care, and keeping them in private is illegal in most nations. Dolphins are only kept in specialist marine facilities, which raises ethical questions because captivity severely restricts natural behavior and frequently shortens lifespans.
