I don’t know what this starfish is doing, but brittle and serpent stars will do this to catch fish (the really big green brittle stars from the Indo-Pacific, Ophiarachna incrassata I think, are notorious for doing this). They create a sort of cage that little fish think is a hiding spot and then once the fish is under it, they twist while the disc goes down (this takes less than a second), trapping the fish. If it stays like that for a while it may be trying to catch something (which, given the species, means it’s likely starving), trying feeding it a piece of shrimp.

Thats weird you say its starving, its been doing fine for ages but he wont take directly food such as mysis chrimp.

I don’t know that it’s starving, just that it could be a possibility. Starfish are notorious for slowly wasting away in aquariums. And for this species, this sort of behavior (actively trying to catch prey) is unusual and could be because there isn’t enough microfauna in the sand for it. Again, it may have plenty of food, was just an idea for why it might be exhibiting this behavior, I could be completely wrong.

Edit: If it won’t take mysis, I would try feeding it something larger like krill or a silverside.

I have one of those ones, its albino and has been with me for a very long time, though he just moved into this new tnk the other day and it was a bit of a struggle at first. Watching them eat silversides when they are this size is pretty incredible.
It reminds me of a kraken, wrapping them up with its "tentacles/legs" very quickly.

Walking? Evolving into human-like starfish?Idk just a guess. Probably what MaxTremors said is the right answer.
