Until 1994, scientists thought there was only one species of Common Dolphin, but later realized that there were at least two species belonging to the genus Delphinus: the Common Short-tailed Dolphin ( Delphinus delphis ), found in the Mediterranean Sea, and the Common Dolph ( Delphinus capensis ) with distribution of the coasts of tropical and temperate oceans. Due to the high morphological variability of this genus, some authors have suggested the existence of an endemic subspecies in the Black Sea ( Delphinus delphis ponticus ), but its taxonomic status has not yet been agreed.

The Common Dolphin is a medium-sized dolphin, with a slender body and a sickle-shaped dorsal fin with a pointed tip. Despite its name, it has a moderately long beak, clearly differentiated from the melon. The lateral fins are thin and pointed.

Coloring is the main feature of this species. The dorsal and lateral parts of the body are dark, with an inverted triangular shape. The abdomen is white or light colored. It has an hourglass design on both sides of the body. The lateral part of the body is yellowish or ocher and the posterior part is grayish.

It has between 80 and 120 small, sharp and pointed teeth on each jaw.

Adult Common Dolphins are between 1.7 and 2.7 meters long. And between 0.7 and 1 meter at birth. They show sexual dimorphism, males are slightly larger (5%) than females, not only in terms of total body length but also in places such as the skull. Adult males have a hump that occurs after birth (Neumann et al., 2002) and is thought to be related to testicular size and helps females choose the healthiest male in terms of reproduction. (Murphy & Rogan, 2006). In this case the males with the largest hump would have larger testicles and therefore higher sperm production.

Distinctive features:

Dolphins are easily recognized by the gray and white stripes that start in the eye area and continue along the dorsal and lateral sides of their body.
