Oceanar.io - a game of survival in the underwater world. You descend to the bottom of the ocean and become an angler fish. To survive, you need to eat plankton, but you can eat other fish that are weaker than you. Also, from eating food, you have companion fish that will protect you. The more you eat, the more you will have satellites. You can combine two small fish of the same size into one large fish to increase its chances of survival. Send satellites to battle with other players in order not to accidentally die yourself.
Beware of jellyfish and the sudden attack of the fish-satellites of other players!
