Purple Mystery Hitchhiker Continuing to Thrive

[AtlasReef]

Still as yet Unidentified purple live rock hitchhiker is translucent, reactive to light and danger from other creatures, will turn almost solid white when withdrawn near the entrance to its hole in the rock.

This is absolutely what it looks like! Everything I read says they don’t retract from danger though. This guy turns almost totally white and pulls in to its hideout. So fun and exciting!
