During a dive at "Japanese Cargo Wreck" at Malapascua Island - with very strong current - I discovered my first Pleurobranchus weberi.
I saw Pleurobranchus weberi before only at Mike Miller's Slug Site. It is characterised by a purple background colour and many large white double rings. This is a very large sea-slug: 18-20 cm.
