Dolphins and whales are magnificent creatures of the sea, and blue whales, in particular, are quite large. They possess a wavelength of 80 to 100 feet, while dolphins come in lengths of 6 to 12 feet. One of the main differences between dolphins and whales is that dolphins have teeth, while baleen is lacking in this area.
The whales with teeth do not use their choppers for chewing, but for tearing its prey into small pieces for easy swallowing. Dolphins are faster swimmers than a whale because they are smaller in proportion and swifter. Whales mostly thrive on plankton, krill, and small crustaceans, and the baleen whales use a unique technique of filtering for catching prey.
Dolphins are known to thrive on fish or sea animals. There is also a difference in the social behavior between the two. Dolphins are friendlier and more charming than whales, and dolphins even swim in groups, as they love to be together.
