Tiaropsis multicirrata

M. Sars, 1835


David Fenwick Snr Does anyone know what species this is? Was found washed up on the shore at Battery Rocks, Penzance today. It's possibly about 20mm in diameter.

Keith Hiscock Don't know - but I know a man who might. I'll take a print into the lab. on Tuesday.

David Fenwick Snr Thanks Keith Hiscock

Rachel Shucksmith could it be Tiaropsis multicirrata (pg 278 of Russel)?

David Fenwick Snr Marie Hawkins at Plymouth University has just identified this as Clytia hemisphaerica.

David Fenwick Snr She used info from North-West European Thecate Hydriods and their Medusa Pt 2. Paul F.S. Cornelius

David Fenwick Snr Chalk and cheese!

David Fenwick Snr Yes same here.

Brendan Oonk This surprises me. I've only seen green Clytia. Is their color influenced by what they eat?
