Terengganu: The public has been advised not to touch venomous jellyfish washed up on several beaches across Terengganu. Senior lecturer at the Faculty of Science and Marine Environment, Universiti Malaysia Terengganu (UMT), Dr. Rosmawati Md Amin, emphasized that although these marine creatures are stranded and separated from their original colonies, the species known as the Portuguese man-of-war still possesses thousands of stinging cells on its tentacles that remain active.

According to BERNAMA News Agency, Dr. Rosmawati pointed out that the assumption that these jellyfish are harmless once dead and washed ashore is incorrect. "Even though they may look like unmoving blue plastic, their stinging cells are still active and can release toxins upon contact," she stated. She warned that a sting can cause intense pain and other symptoms such as dizziness, body aches, and respiratory distress. In certain cases, the sting can trigger severe allergic reactions, necessitating immediate hospital treatment.

Dr. Rosmawati also advised beachgoers to wear shoes or sandals when walking along the beach to avoid accidental contact with the jellyfish. She explained that this species, also known locally as 'ubur-ubur api' (fire jellyfish), is commonly found washed up on the East Coast, particularly in Terengganu, during the Northeast Monsoon (MTL) season due to wind and ocean currents.

The lecturer added that the use of vinegar to alleviate the pain of a sting remains a subject of debate and is only suitable for certain species. However, she noted that warm water is among the recommended treatments for soothing or reducing pain. Dr. Rosmawati also urged fishermen or individuals engaged in fishing activities to be cautious when handling jellyfish caught in their nets.

Over the past few days, the presence of these venomous jellyfish has been detected once again at several popular tourist locations, including Pantai Pandak in Cendering and Pantai Paka in Dungun. The marine hydrozoan is easily identified by its translucent bluish colour and a gas-filled float on top, with sizes typically ranging from two to 10 centimetres.
