Sand star in pool at edge of sandy shore

Observation - Sand star in pool at edge of sandy shore. Description: I came across this 10cm starfish moving slowly in a pool formed between a sandy shore and mussel covered boulders and assumed it was a common starfish at first, but the arrangement of spines makes this a Sand star I believe, a which must have been washed

I came across this 10cm starfish moving slowly in a pool formed between a sandy shore and mussel covered boulders and assumed it was a common starfish at first, but the arrangement of spines makes this a Sand star I believe, a which must have been washed in during a storm.
