Siren Sun

Sun:the male siren in the image, he is curious and friendly, he is extremely playful and lives the surface and really wants to go but Moon won't let him saying it's dangerous, doesn't get how humans can survive on the surface for so long at a time whilst still being able to swim for hours on end, he is very fast but means no harm to others only fish since he eats fish. Moon:a male siren, he is bluer and darker coloured then Sun, he is against going to the surface out of fear of being separated from Sun, He tries to make the ocean floor more fun for Sun by going into the deps and taking shiny shells and rocks to Sun so he can add to his collection, deeply cares for Sun, is very intelligent fully understanding how scary humans are and how dangerous they are. Olive:a male human who went scuba diving really deep in the ocean and was found my Sun first then Moon a few minutes later, he is around the same size as Sun and Moon but Sun and Moon are longer due to their ling tails, he didn't know about the existence of sirens till he saw Sun and Moon.
