There was complete panic on Pranburi Beach in Prachuap Khiri Khan Province.
The small coastline was suddenly filled with thousands of strange, transparent, needle-like creatures.
Their appearance has caused widespread concern and curiosity on social media, The Thaiger reports.
Experts believe that sea snails from the Pteropod order have appeared on the shore.
The last time this species caused a stir was in 2021, when they were found on Ban Krut beach.
The potential danger posed by these creatures is a concern.
The danger is that the needle-like sea snails can pierce the skin.
Tourists and children were advised not to enter the water until these mysterious creatures disappeared.
