Nearby units lower than Seagull's level heal 25% of max health per second, except for Jellyfish, your main food
The Oarfish is a blue and reddish, "fish" in Deeeep.io. It is known for being the Deep Sea counter to Jellyfish. It is a 9th tier animal in Deeeep.io. It can heal any animals lower than Seagull except Jellyfish. It evolves from the Octopus and evolves into the Giant Squid and Cachalot. It is equivalent to the Hammerhead , Dolphin, Leopard Seal and Narwhal
Eat Anglerfish, and Jellyfish as their your main source of food, and stay away from Giant Squids.Another good strategy is to pretend you are not playing by staying still and lure someone in that way (octopuses work good).
