So many of these present on this beach today! I could have collected 100 if I had wanted to. This is the largest number I have ever seen here.
The big ones are about 10 mm in length. They seem mostly to be adults with a few juveniles as well, but the juveniles of this species can be so very small that they are easy to overlook.
I don't know if the tellins had been killed by the cold and ice, or whether many of them were still alive and had simply been washed up by the storm.
