Synopsis

Using underwater photography, magnified close-ups, and footage captured through a microscope, the film reveals the intricate nature of the sea urchin. The viewer observes the sea urchin's mouth and the movement of its five teeth as they open and close. After a gelatin injection, the shell is removed to expose the internal muscle structure, digestive tube, and reproductive organs. Magnified views of the stems show suction cups at their ends, which extend and contract to aid in movement. Microscopic calcareous stems are visible, with jaws at their tips serving various functions. Cilia throughout the body are constantly in motion, agitating water and debris. The soundtrack features African music that evokes the rhythm of a shuffle dance.

How many hands made this film

The scale of the collaboration

Principal cast & crew: 1

These are the principals we have on file — the full crew ran to the hundreds. Every film this size was made by far more hands than any credits list ever names.

Why a floor?

This is a minimum, not a total. We only count the credits we’ve captured so far, and coverage is uneven — a blockbuster might show a few hundred names while another of the same size shows a couple dozen. The real crews all ran into the thousands. The number here only grows as full credits are enriched — so we frame it as a floor, never a headcount.
