SEMPORNA: Increased seawater temperatures may be behind the massive blooming of thimble jellyfish off Mabul Island here.
Seagrass Guardians marine biologist Michael Yap said the phenomenon is neither frequent nor seasonal but is driven by specific environmental triggers.
"Jellyfish have a unique life cycle, both sexual and asexual. The blooming could be due to certain conditions, such as increased seawater temperature, which boosts their asexual reproduction mode.
"If they bloom, they will be in the millions. Their adult size is about 1mm to 3mm. They are so tiny that they can easily slip into clothing and sting," he told the New Straits Times.
Wilderness and dive physician-in-training Dr Muhamad Na'im Ab Razak said that while incidents have been documented in Mabul and Lahad Datu, cases in Sabah are likely underreported.
He said contact with the species can cause "seabather's eruption", a condition where jellyfish larvae become trapped under swimwear and release toxins.
"Contact with thimble jellyfish may cause skin itchiness, redness, discomfort, and nodular dermatitis. While it is non-lethal, it may become infected if not properly managed," he said, advising the public to seek medical treatment for symptoms.
Dr Muhamad Na'im also recommended avoiding water activities or wearing full-body protective clothing during a bloom.
Addressing common misconceptions, he cautioned against the use of vinegar for this specific species.
"Vinegar is only for box jellyfish stings. For seabather's eruption, rinse with seawater or use medically approved products," he said.
