Something MUST be done!

The most immediately obvious of these things is their lovely, green colour which matches Halimeda perfectly. Good start! Then there are the strange flaps and sticky-out bits on their legs and body that match Halimeda's leafy segments. Nice! Many creatures would leave it at that, but not the Halimeda Crab. They use their head,,,
The Halimeda Crab will now pick up a piece of authentic, honest to goodness Halimeda and attach it to his head. It's the perfect final touch! Now he can walk around and even fall over like a complete buffoon (at the slightest current if he's particularly ambitious about the size of algae he wants on his noggin) and he just looks like a bit of algae because he partially is a bit of algae.
AND he's turned himself from a crunchy, tasty snack to a crunchy, tasty snack with a side dish of algae. And no self-respecting predator wants that.
