Blue sharks get their name from their beautiful blue colour. They have distinct indigo blue on their backs, vibrant sapphire blue along their sides and white underbellies. This species is one of the most widespread and easily recognizable sharks. Because of their inquisitive nature and need to gently investigate everything and anything that crosses their path, they have earned the nickname “blue dogs” or “puppies of the sea.”
