Devonshire Jellyfish

Observed: 17th August 2009 By: afishwishafishwish’s reputation in Invertebratesafishwish’s reputation in Invertebrates

The sea at Slapton Sands, Devon, was teeming with these jellyfish, you could see one about every 5 metres along the coast. I was unlucky enough to front crawl into one face first, luckily the sting only lasted a couple of hours.

Hi, it is a compass jellyfish

Hi, it is a compass jellyfish the distinctive pattern on the top of the bell is unmistakable! they are native to British waters and can be found all round the coast. They are a pelagic (open ocean) species with the majority seen near the coast being juveniles which have a less painfull sting but still not pleasent!

Hi Rupert,
They were much bigger than 4cm, probably more like 15cm - 20cm diameter. afishwish
