This comes in halves held together by rare-earth magnets. It's solid when assembled, and then you can pull it apart to get at the interesting cross-section.
I like that it sits on the boundary between plant and animal: clearly a swimmer when whole, but the halves belong, irresistibly to a fruit.
Plankton drifts. Nekton swims.
