The Marlin is a large hostile fish encountered in Stranded Deep. Marlin are often found in Deep Ocean biomes.


Marlin are often seen travelling through the water alone. When idle, the marlin is docile and will swim aimlessly around the ocean. When detecting the player, they become aggressive and will attempt to flip the player's raft over by forcefully ramming into them, knocking anyone on-board into the ocean. The marlin will do this from below, often without any warning, so one must exercise caution when passing over them. If encountered in the water, the marlin may charge the player and attempt to slash their character with their long bill, causing serious bleeding.

With a health level as low as 125, the marlin is considered the most fragile hostile creature in the game as of the current build. However, what they lack in health they make up for in speed, as they are extremely fast and hard to catch.



  • Marlin are the only member of the billfish family to appear in the game thus far.
  • As of v0.03.H2, the spawn chance of a marlin has been adjusted from 100% down to 25%.
