Specimen above was found cast up on the strandline after a storm at Gwithian, Cornwall, 26.02.14.
The specimen here looked a little odd, hydroid expert Dr. Peter Schuchert kindly explained why.
The specimen is a young Sertularia argentea or S. cuppressina, on which is growing another, stolonial hydroid, with hydrotheca. The stolonial hydroid looks like Campanulina pumila, but it is impossible to tell without seeing the rim of its hydrotheca. The hydrotheca of the stolonial hydroid, should not be confused with gonothecae of Sertularia argentea or S. cuppressina which are not present.
