Can anyone id these please?
I suspect a sea urchin and a starfish of some kind

Better images would help, but that might be a black longspine urchin (safe but still venomous).

From my research it's an urchin
Last night in the dark I found a number of large snails. Maybe cone shell. It was 1/2 inch long conical with shiny shell. But due to location I could not get a good look.

Also found a rather large bristlestar. Maybe 2 inch dia.
