again a larva from a Cnidarian ?

Maybe again a planula larva from a Cnidarian? But this time in red! The diameter was 465 µm.
A difficult question: Do the colours of animals from the micro-plankton have a function for other animals?

First image is my favourite. In my humble, uninformed opinion colour always have a functional role. Not sure what it might be here.
