The Morbakka jellyfish (Morbakka fenneri) is a type of Irukandji jellyfish that occurs naturally in Moreton bay. It can grow to around 15cm long and is usually found in isolation rather than swarms.
The sting of a Morbakka jellyfish can cause Irukandji syndrome - a collection of symptoms that include:
- severe lower back pain
- breathing difficulties
- profuse sweating
- severe cramps and spasms
- a feeling of impending doom.
No fatalities from Morbakka have been recorded on Redlands Coast, however all incidents have required urgent medical assistance. One case in prior years has required life support.
Avoiding Morbakka stings
To avoid an Irukandji Morbakka sting:
- swim between the red and yellow flags (if present)
- ask lifeguards about recent stings and read warning signs
- wear protective clothing such as a full body lycra suit, sun-suit, dive skin, rashie or pantyhose
- carry a bottle of white or brown vinegar in your boat or car
- if you see a Morbakka (or are stung), get out of the water and alert others immediately.
What to do if stung
If you, or someone you know is stung by a Morbakka jellyfish, follow these steps:
- Call for help on 000 and alert the lifeguard.
- Treat the patient - administer CPR if you need to.
- Treat the sting - flood the sting with vinegar.
- Seek further medical help.
Council's role in protecting the public
The Redland City marine environment is home to a number of marine stingers. During periods of risk to public safety, council may erect warning signs and take further steps to protect the public.
