You’re on holiday in Curaçao—hooray! 

Sun, sea, and stunning beaches are waiting for you. But just like on other tropical islands, it’s wise to be aware of some marine life you might encounter. Most people never run into trouble, but knowing what to do if you do come across certain sea creatures can save you from an unpleasant experience.

Here are the main animals to keep in mind when exploring Curaçao’s waters—and what to do if you meet them.

Fire Coral (Brandkoraal)- Fire coral isn’t actually a coral but a stinging organism that can cause skin irritation. You’ll often find it on ropes, buoys, or underwater structures. Touching it by accident can result in a painful rash.

What to do if stung:

  • Leave the water immediately.
  • Do not rinse with fresh water, as this can worsen the sting.
  • Apply white vinegar to neutralize the irritation.
  • Cool the area with a cold compress.

If you develop a fever, pus, or worsening pain, contact a doctor. Otherwise, the discomfort usually fades on its own.

Lionfish (Zeeduivel / Koraalduivel)- Beautiful but venomous, the lionfish has long, striped spines that deliver a painful sting if touched.

If stung:

  • Wash the wound with soap and water.
  • Soak the affected area in hot water (up to 45°C) for 30–90 minutes. The heat helps break down the venom proteins.

Seek medical help if pain is severe, if you feel sick, or if you notice signs of an allergic reaction.

Portuguese Man o’ War (Portugees oorlogsschip) Despite its jellyfish-like appearance, the Portuguese man o’ war is actually a colony of polyps with long, venomous tentacles. Its sting can be extremely painful and dangerous.

If you see one:

  • Don’t enter the water.
  • Warn others nearby.
  • Notify local authorities or the lifeguard.
  • Never touch it—even if it looks dead on the beach. Tentacles can remain venomous for hours.

If stung:

  • Rinse with vinegar or saltwater (not fresh water).
  • Carefully remove any tentacles with a plastic object or tweezers—never bare hands.
  • Seek medical attention, especially if pain is severe or you experience allergic symptoms.

Stonefish & Sea Urchins (Steenvis & Zee-egels) Stonefish are masters of camouflage, blending into the seabed, while sea urchins hide among rocks and coral. Both can deliver painful stings.

If stung:

  • Immerse the affected area in hot water (43–45°C) for 30–90 minutes.
  • Rinse with seawater (not fresh water).
  • Remove visible spines gently with tweezers.
  • Disinfect the wound.
  • Take pain relief such as paracetamol if needed.

See a doctor if:

  • You cannot remove all spines.
  • Signs of infection appear (swelling, pus, fever).
  • You notice an allergic reaction.

Prevention tip: Wear water shoes when swimming or walking in rocky areas.

Final Thoughts
Curaçao’s underwater world is breathtaking, and encounters with dangerous marine animals are rare. By staying alert, wearing protective gear, and knowing basic first aid, you can safely enjoy snorkeling, diving, or just a swim in the Caribbean Sea.

So, don’t worry too much—pack your sunscreen, fins, and snorkel, and most importantly, enjoy your tropical adventure!
