The bottlenose dolphin on the Dolphin Visa Gift Card is the best known of some 40 dolphin species. Highly intelligent, they have the higher brain-to-body-mass ration of any mammal, nearly that of humans. More than 45 years of research have shown dolphins comprehend signals and symbols, recognize speech patterns, sequences and numerical values, and they understand gestures made by human hands and eyes. With all that brain power, it’s a good thing they like people. Celebrate our good seaborne friends with Dolphin Visa Gift Cards.
