Box Jellyfish (Irukandji)
The box jellyfish is one of the most dangerous marine animals found in northern Australia, particularly in warm coastal waters. Its nearly transparent, cube-shaped body and long, venomous tentacles can cause excruciating pain, heart failure, and even death in humans.
To reduce risk, swimmers are advised to heed warning signs, wear protective clothing, and avoid the water during jellyfish season.
