When the sea and beach turned red, Wherrytown, Penzance, 06.09.17. The remnants of a bloom of the non-native fine red seaweed Antithamnionella ternifolia was observed on the beach near the low water mark and beyond low water in the sea. In some areas the sea was very red indeed, the situation was caused by an increase in spread of this non-native species in Mounts Bay in 2017, which had been removed during a recent gale. This species is an important non-native species and it can foul literally anything.
