Sand urchins wash ashore in large numbers at Nha Trang beach

Large numbers of sand urchins have been washing ashore along the coast of Nha Trang, appearing in high densities near the water's edge. The creatures are described as being roughly the size of half a rambutan, white with brown stripes, and covered in stiff, wire-like spines.

Dam Hai Van, Director of the Nha Trang Bay Management Board, stated that the sudden appearance is due to the breeding season and currents pushing them toward the shore. While the urchins do not pose a high level of toxicity or cause poisoning like jellyfish, stepping on them can cause itching, discomfort, swelling, or pain. Children and individuals with sensitive skin are advised to be particularly cautious.

Nguyen Tac An, former Director of the Nha Trang Institute of Oceanography, noted that this phenomenon is a natural occurrence. He explained that sand urchins typically live at depths of 10 to 16 meters, but changes in weather or strong sea disturbances can push them toward the coast. He added that these organisms play an important role in the marine ecosystem by filtering water.

Authorities have been collecting the urchins that wash up on the sand, though retrieving those remaining underwater is difficult. Local officials recommend that tourists and residents observe the shoreline carefully and avoid walking barefoot in areas where the creatures are present.
