Ynghylch

The mauve stinger is a small jellyfish, but it certainly packs a powerful punch, with long tentacles and warty structures on its ‘bell’ full of stinging cells. Small crustaceans known as amphipods hang out inside the ring of tentacles and are able to survive unharmed. The mauve stinger likes to feed on other small jellyfish and oceanic sea squirts, also known as ascidians.

Sut i'w hadnabod

This jellyfish usually appears a bluey purple (mauve) colour with a globe shaped umbrella covered in orangey brown warts. Long, thin tentacles hang down from around the bell, reaching a maximum of 3 metres.

Dosbarthiad

Fairly uncommon close to UK shores, but may be found offshore and in warmer European waters such as the Mediterranean.
