There are almost forty species of dolphins. They're closely related to whales/porpoises and are found worldwide, eating mostly fish and squid. Dolphins have a streamlined body designed for fast swimming. The tail fin is used for propulsion while the pectoral fins, together with the entire tail section, provide directional control. The dorsal fin, in those species that have one, provides stability while swimming.
