Nudibranch

They don't guard their eggs, @Lauren.
There's thousands of eggs, many will not hatch/survives as they get feed on by other animals including other nudibranch.

So beautiful, I had no idea they laid their eggs in ribbons. Do they then guard them?

Thanks, Ashley :)
Actually, the eggs of another specie of Nudibranch called Spanish Dancer (Hexabranchus sanguineus) is red in color and they can looks like 'roses' :)

Beautiful photo, Albert! The eggs make it look like it's sitting on a flower :)
