tropicalis, the Indo-Pacific common dolphin bairdii, the Eastern North Pacific long-beaked common dolphin Currently, the common dolphin is divided into four subspecies: Therefore, long-beaked and short-beaked common dolphins are now listed as the same species under the scientific name of Delphinus delphis. Recent evidence has demonstrated that different populations of long-beaked common dolphins around the world are not closely related to one another and are often derived from a short-beaked ancestor (as well as not sharing common derived characters). The current standard taxonomic works recognize this as a subspecies of D. tropicalis, common name usually Arabian common dolphin or Indo-Pacific common dolphin), characterized by an extremely long and thin beak and found in the Red Sea and Indian Ocean, might be distinguished from the long-beaked species. This study also suggested a third species ( D. This analysis was seemingly confirmed by a more in-depth genetic study in the 1990s. For this reason, they are no longer considered different species. However, recent evidence has shown that many populations of long-beaked common dolphins around the world are not closely related to one another and are often derived from a short-beaked ancestor and do not always share common derived characteristics. The common dolphin was originally categorized into two different species (now thought to be ecotypes), the short-beaked common dolphin and the long-beaked common dolphin. The common dolphin belongs to the subfamily Delphininae, making this dolphin closely related to the three different species of bottlenose dolphins, humpback dolphins, striped dolphins, spinner dolphins, clymene dolphin, spotted dolphins, fraser's dolphin and the tucuxi and guiana dolphin. It is presently the only member of the genus Delphinus. However, the common dolphin is often depicted in Ancient Greek and Roman art and culture, most notably in a mural painted by the Greek Minoan civilization. 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.
The common dolphin ( Delphinus delphis) is the most abundant cetacean in the world, with a global population of about six million. Delphinus novaezelandiae Quoy & Gaimard, 1830.
