Found something in beach sand ID Please

[pakora]

I scooped up some sand from the beach near the shore and this was in it... does anyone have a clue as to what it is!?
intently waiting for some help. Thank you

Sand sifting crabs, or sandcrabs. The one in the foreground has an egg sac. They generally don't live long in the tank in my experiences with them. You could try keeping them alive by feeding them zooplankton once every day or two.

just dont return it to the beach you could inadvertantly expose the beach area to foreign pathagen or disease.
