Worm or Nudi?

Can someone please help me with the id of this worm/nudi? It's around 6-7 cm long and really fast moving.

The picture is taken in Karimunjava Marin Park loctade in the Java Sea.

Flatworm. Looks like Pseudobiceros bedfordi.

Marli's got it pegged as usual. In general, if the animal is flat & moving fast it's a flatworm. Most slugs are fairly slow except for the ones that prey on other slugs.

Thanks for your answers.
