Spiders
The dead spider is in pieces. Each fragment is separated into other boxes, set on a wooden table. Each box is without a lid.
The limbs are separated into their own boxes, each needle thin and pointed, sharp enough to puncture. They're jointed half way down and one of them is jammed.
The body's tiny, but observation under the available microscope shows a detailed interior of gears and a tiny, tiny radio transmitter. That is no longer transmitting.
