Diving safety
Venomous. This fish has venomous spines. Stings happen on contact, not as an attack — keep your distance and never handle it.
If it happens
- Leave the water and keep the injured limb still and below heart level.
- Immerse the wound in hot water (about 45 °C / as hot as tolerable) for 30–90 minutes to break down the venom.
- If breathing is affected or the person faints, treat it as a medical emergency.
