Can You submit a broader view of the specimen (whole thalli/filament). After current pictures, it is similar to Rhodomela sp. beacuase Ceramium has internodes and cortex alternatively.

Dear Priit

The answer to your question is unfortunately no!

This seaweed was chewed by rabbit fish and the thalus remained was cylindrical branches! I don't think that this is Rhodomela sp. although the outer cells look a bit similar.

Is it possible that this is Alsidium sp? A. corallinum?

It is probably Alsidium helminthochorton
