While out at Ross last weekend, we noticed a strange phenomenon of a mussel (Mytilus) bed in the sand. The whole beach up to a certain point was covered in small (~2cm) mussels. Normally mussels are attached to a hard substrate, to give them support against being washed out with the waves.
Last year, in July, there were no mussels in the same place. So either the mussels did not grow there last year. Or I think more likely, the mussels will all get detached and/or eaten by July, and just had the poor luck to settle in such an unfortunate place.
Do you have any information or insight on this? I’ll keep my eye on them next time I return to Ross so see for myself.
