What the heck did I find?

I spotted this critter early this morning at about 18-20m near Anilao. It is pretty clearly some sort of shrimp but looks like some kind of mashup between a shrimp's legs, a cowrie's mantle, and maybe a rhinopia's camouflage. I was trying to find a better angle but it was quite shy and after two shots it vanished into its crevice. I couldn't come up with the right search terms to even get close on the google. Someone please help satiate my curiosity!

Saron shrimp!

Good find

Fantastic! Thanks a lot for the ID!

No worries, I have seen variants in Indonesia and Australia. Always a pleasure to see

I found one of those in Tufi, PNG and was similarly confused. It wandered through a coral head that made it very hard to get a full body shot. They are weird looking creatures. Great shot!
