Spotted Dolphin
SPOTTED DOLPHIN
Stenella frontalis
The Atlantic spotted dolphin (Stenella frontalis) is a medium-sized dolphin distinguished by its unique spotted pattern, which becomes more prominent as individuals age. Calves are usually born almost unspotted, and the number and size of spots increase gradually throughout life, covering the body, flanks, and sometimes the dorsal fin. This highly social species typically forms large groups of 50–100 animals and may associate with other dolphin species. It inhabits warm temperate and tropical waters of the Atlantic Ocean, feeding mainly on fish and squid. These dolphins are active and agile, frequently leaping and performing acrobatics at the surface. In Portugal, sightings are rare along the continental coast, and relatively little is known about their local populations.
