Sorry if this is the wrong place to post but I didn't see any top lines subjects that seemed to fit. Any chance I can get some help identifying this snail and starfish?
Thanks!!!

The starfish looks like a sandsifter, not sure on the snail do you have better pic without the blue light?

Just thinking the snail could be an orange spot nassarius if it has orange spots?
