Rayong –
A rare natural phenomenon has stunned visitors at Suan Son Beach in Rayong Province, where millions of pink sea cucumbers were swept ashore, turning long stretches of sand into a striking red‑pink hue. The unusual sight drew crowds of curious tourists and prompted immediate investigation by the Department of Marine and Coastal Resources.
The Minister of Natural Resources and Environment, Suchart Chomklin, ordered a rapid assessment led by Dr. Pinsak Suraswadi, Director‑General of the Department. Marine experts confirmed that the creatures are sea cucumbers, specifically the pink spiny variety (Cercodemas anceps), soft‑bodied invertebrates that resemble cucumbers or sausages, covered with small bumps or spines in shades ranging from bright pink to reddish‑orange.
Sea cucumbers play a vital role in marine ecosystems, earning the nickname “housekeepers of the sea.” By breaking down organic matter and recycling nutrients on the ocean floor, they help maintain ecological balance and support the health of coral reefs and other marine habitats.
Officials believe the mass stranding was triggered by strong winds and turbulent waves associated with recent storms, which displaced the animals from their seabed habitat and carried them ashore. While such events are rare, they are considered natural occurrences rather than signs of ecological distress.
Authorities have cautioned visitors against direct contact with the stranded sea cucumbers. Some species release defensive chemicals that may irritate sensitive skin. Tourists are advised to admire the spectacle from a safe distance while scientists continue monitoring the situation.
This comes one-day after thousands of clams and mussels were found on Jomtien Beach.
