"What Are Those Pink Creatures Washed Ashore?"... Thailand Surprised by Series of Marine Life Sightings

Thai Authorities: "Likely Washed Ashore by Strong Waves"
Tourists Advised Not to Touch Due to Skin Irritation Concerns

A rare phenomenon occurred on a beach in eastern Thailand, where the shoreline was covered with numerous pink marine creatures, prompting a local government investigation.

On June 11, Yonhap News TV, citing Thai local media and statements from marine authorities, reported that millions of pink sea cucumbers were washed ashore by waves at Suan Son Beach in the Pae area of Mueang Rayong District, Rayong Province. Several hundred meters of the beach were tinged with shades of red and pink.

The Thai Marine and Coastal Resources Authority, which conducted an on-site investigation, revealed that the organism is a type of sea cucumber known as the "pink sea cucumber (Cercodemas anceps)" or "pink thorny sea cucumber." NATION

Tourists and residents discovered the mass of marine creatures washed up on the beach early in the morning and reported it to authorities. The Thai Marine and Coastal Resources Authority, which conducted an on-site investigation, revealed that the organisms are a type of sea cucumber known as the "pink sea cucumber (Cercodemas anceps)" or "pink thorny sea cucumber." These sea cucumbers have soft, cylindrical bodies characterized by small bumps or thorn-like projections on the surface. Their coloration ranges from pink to red and even orange. They primarily inhabit sandy seabeds or areas near rocks, where they are known to contribute to the marine ecosystem by breaking down organic matter and decomposing animal remains.

Authorities believe that this phenomenon was most likely caused by the recent spell of strong winds and waves, as well as adverse weather conditions. It was explained that the sea cucumbers, which normally reside on the seabed, were swept ashore by the turbulent waters. The on-site investigation confirmed that some of the sea cucumbers were still alive, and it is possible that they may return to the ocean with the next high tide.

However, authorities have advised tourists not to touch or step on the sea cucumbers. While most sea cucumbers are not deadly to humans, some species may release defensive substances when stimulated, which can cause itching or irritation, especially for those with sensitive skin. So far, there is no clear evidence that this mass occurrence was caused by marine pollution or an ecological abnormality. Authorities stated that it appears to be a rare natural phenomenon, but they plan to continue monitoring water quality and the surrounding environment.

Meanwhile, other toxic marine organisms have also been appearing recently on Thai beaches. On June 4, bluebottle jellyfish were discovered at Bang Sak Beach and Ban Nam Khem Beach in Phang Nga Province in the south, prompting authorities to issue warnings to tourists to avoid contact. Bluebottle jellyfish, which have blue or purple gas-filled sacs, can cause severe pain and skin irritation if stung by their tentacles. Thai authorities noted that during the monsoon season, strong waves and currents can increase the likelihood of marine organisms being washed ashore. They urged the public not to touch unfamiliar organisms found on the beach and to immediately report them to on-site managers or relevant authorities.
