McCosker I.d.ed this for Rebecca over the phone. Alison found it. It pushed itself back down into the sand...
Burrowed into the wet sand with just its head sticking out. Very aggressive!
Id'ed by John McCosker. Thanks, John!
My son found the animal flopping on the sand next to shallow water. He helped it into the water and it rested there for about a minute (photo). Then it wriggled backward into the sand, with just its head sticking out. This was during a low tide after a high tide and large waves.

Se encontró, junto con la anguila ciega,en un cuerpo de agua que fluctúa según la temporada de lluvias y no alcanza un metro de profundidad.
Otra característica de la cueva era que tenía poco oxígeno y alta cantidad de dióxido de carbono.
