Stinging presence: Portuguese man o’ war littering Pantai Rhu Muda in Terengganu. — Bernama
MARANG: The public has been advised to be wary of the presence of hundreds of venomous Portuguese man o’ war, which washed ashore at Pantai Rhu Muda here.
The species superficially resembles a jellyfish, but is actually a siphonophore, an animal made up of a colony of organisms working together.
Universiti Malaysia Terengganu (UMT) Faculty of Science and Marine Environment senior lecturer Assoc Prof Dr Roswati Md Amin said the species, classified under the marine hydrozoan group, is easily identified by its translucent bluish-purple or pink tinge.
The Plankton Ecophysiology expert said the species has venomous stinging cells in their tentacles, which serve to capture prey and as a defence mechanism.
As such, she advised the public not to touch the poisonous marine creatures, including those that are dead, as they can pose serious risks.
“This species is commonly found in the Pacific, Indian and Atlantic Oceans.
“However, last November, we found this species on the beach near UMT in Kuala Nerus.
“These colonial creatures can’t swim. They move using their float-like polyps, which measure between 2cm and 10cm to navigate.
“They also move according to ocean currents and wind.
“Research shows that the strength and direction of wind influence their presence on shorelines.
“The strong northeast monsoon season winds are among factors causing them to wash ashore,” she told Bernama.
As such, Roswati urged authorities to monitor the presence of these marine creatures in beach areas frequented by visitors.
This ensures public safety, especially that of children who are easily excited by the discovery of these unique marine species.
“I also advise fishermen to be more careful because these creatures can easily get caught in fishing nets,” she said.
