Common dolphins (Delphinus delphis) are highly social and energetic marine mammals known for their striking appearance and playful behaviour. They are widely distributed in warm and temperate seas worldwide. They possess a long, slender beak and a streamlined body adapted for fast swimming. They can reach speeds of up to 60  kilometres per hour (37 mph). They are easily identified by their distinctive hourglass pattern with a golden yellow patch on the flanks. Common dolphins often travel in large pods, sometimes numbering in the hundreds or even thousands. Highly vocal, they use clicks and whistles to communicate and hunt cooperatively for fish and squid. They can often be seen performing acrobatic jumps and bow-riding alongside boats.
