Crinoid Commensal Shrimp

This Crinoid Shrimp is rather small, around 1 cm in size, and slender.
It lives among Crinoid, taking to the colour of the Crinoid, for this instance, it is goldish/brownish, very well camouflaged.
In Pic#3, she was moving/swimming from one arm of the Crinoid to another, thus exposing the eggs she is carrying in her underbelly.
