A cool video has emerged of dozens of dolphins swimming along a small fishing boat in the Sea of Cortez, Mexico.<br /><br />The footage, shot last month, show the creatures playfully swimming near the boat. <br /><br />"The dolphins seemed so playful, the faster the boat went the faster they went," the filmer wrote online. <br /><br />"Our driver even started doing donuts and they criss-crossed the boat. Wonderful experience!"
