Males are generally longer and heavier. The color pattern on the body is unusual. The back is dark and the belly is white, while on each side is an hourglass pattern colored light grey, yellow, or gold in front and dirty grey in back. They have long, thin rostra with up to 50�60 small, sharp, interlocking teeth on each side of each jaw.
Common dolphins live in both warm-temperate and tropical waters ranging from 40�60�N to 50�S. Long-beaked common dolphins mostly inhabit shallow, warm coastal water. Common dolphin have a varied diet consisting of many species of fish and squid. This includes both mesopelagic species and epipelagic schooling species. They have been recorded to make dives up to 200 metres (660 ft) deep.

They are fast swimmers (up to 60 km/h), and breaching behavior and aerial acrobatics are common with this species. They are also known to display altruistic behaviors to support injured members.
