Aquatilis

Alex, a marine biologist, nearly dies while exploring the White Sea in Russia. Now in a coma he's taken for treatment to Moscow but regains consciousness only to discover that a parasitic creature from the ocean is living inside him. The two of them will have to cooperate and understand each other if they are ever to survive and return to the sea. Aquatilis is a unique story told through the perspective of the ocean trapped in a human's body.
