| Several thousand long-beaked saddleback dolphins sometimes swim together, although the average size of a school is closer to 200 individuals. This species lives close to shore in tropical and temperate waters. In the eastern Pacific, they have been recorded from California south to Peru, and in the western Atlantic, from Venezuela to Argentina. The dolphins feed mainly at night, deep underwater, on fish and squid. Calves are usually born in the spring or summer, after a gestation period that is probably about 10 or 11 months. Much remains to be learned about this species.
