  • Stonefish: These fish have spines on their backs. If touched or stepped on, these spines exude venom. They have mottled skin that helps them camouflage in their surroundings.
  • Lionfish: These have long, thin spines on their backs and bellies. These spines are venomous and can cause intense pain, swelling and respiratory distress.
  • Pufferfish: These have a beak-like mouth with sharp teeth for defense. Some contain a toxin called tetrodotoxin that can cause paralysis and death.

Stonefish is hard to spot, as it is well-camouflaged. It has spines on its dorsal fin that contain poison. If untreated, it can cause pain, paralysis and even death. You can recognise it by its mottled look and tendency to hide in sand or mud.

Lionfish have long and venomous spines on their dorsal and pectoral fins. Its venom can cause swelling, muscle weakness and breathing issues. Look out for its stripes and long, flowing fins.

Scorpionfish have venomous spines on its dorsal fin, gill cover and anal fin. It can lead to pain, swelling and respiratory distress. Spot them by their bumpy texture and liking for reef structures.
