Starfish ID

These all look like Astarias vulgaris to me, as with the other photos. A species from that genus most likely at least.

Did you note the enclosure number? Assuming this is the Polar Play Zone touch tank, the species in that enclosure would be Bat Star, Giant Pink Star, Leather Sea Star, Ochre Sea Star, and Rainbow Star as of my August list. I can get you an updated list if you managed to get that enclosure number.

The big one in the center of this photo is definitely Pisaster brevispinus.

There are three species in the photo, the orange stars are Pisaster ochraceus, the pink stars are Pisaster brevispinus and reddish orange star (third from the right) is Orthasterias koehleri

@birdsandbats This is the Polar Play Zone touch tank, but I was unable to find the exhibit number.
