Komodo's waters are home to several species that can cause injury if handled or encountered carelessly. However, unprovoked attacks on divers are extremely rare. The vast majority of incidents result from accidental contact, not aggressive behaviour.
| Species | Risk | How Injury Occurs | Prevention |
|---|---|---|---|
| Blue-ringed octopus | Extremely venomous (no antivenom exists) | Bites only when handled — almost always a result of picking them up | Never touch or pick up any small octopus. Admire from a distance. |
| Lionfish | Venomous dorsal spines (very painful) | Accidental contact with spines when touching reef or kneeling | Maintain buoyancy, avoid touching reef surfaces |
| Stonefish | Most venomous fish in the world (extremely painful, potentially fatal) | Stepping on or touching — perfectly camouflaged on rocks and sand | Never stand on the seabed; maintain buoyancy at all times |
| Fire coral | Stinging cells cause painful rash and burns | Accidental skin contact while brushing past reef | Wear full wetsuit, maintain buoyancy, avoid reef contact |
| Sea snakes (banded sea krait) | Highly venomous but extremely docile | Bites are exceedingly rare — almost always from harassment | Do not touch or corner sea snakes; give them space to pass |
| Box jellyfish | Stinging tentacles, potentially serious | Swimming through tentacles at the surface or during entry/exit | Wear full wetsuit for protection; particularly risky Nov–Mar |
| Cone snails | Venomous harpoon-like tooth (potentially fatal) | Picking up the attractive shell | Never pick up or handle cone snails |
| Reef sharks | Minimal risk to divers | Not aggressive toward humans; no recorded attacks on divers in Komodo | Remain calm, do not chase or corner |
Key rule: The diving glove ban in Komodo exists for a reason. Without gloves, divers instinctively keep their hands away from the reef, which prevents the vast majority of marine life injuries.
