Acéra ou Le bal des sorcières
In mud flats along the coast of Brittany we watch acera, small ball-shaped mollusks that are about two inches in diameter. They rest in mud; then, in water, they dance, their skirt-like hood spreading like a dervish's cassock. They spin and spin. The film adds musical accompaniment.
Diatomées
The one-celled long and slender diatom, up close: discovered in 1703 with the invention of the microscope. We observe them magnified 10,000 times: water expelled through the skeleton, mucilage constantly emitted, allowing it to glide. Their energy comes from sunlight. They divide and disperse.
Les amours de la pieuvre
An octopus slithers into a narrow crack near the shore; we see its eye up close. It feeds on a crab. In spring it's time to mate. A male grabs a female; he inserts his third arm in her respiratory cavity. We watch another pair: a larger female is the aggressor here. Mating is repeated over hours and days.
Histoires de crevettes
After a comic introduction, we look closely at a shrimp. Eyes on stilts, color patterns, pinchered walking feet, a rostrum. We watch shrimp eat using a strong claw and a fine one; we watch digestion. After eating, shrimp clean themselves. The female lays eggs that cling to her feet. After three weeks, the eggs hatch explosively.
Comment naissent les méduses
At a marine biology station, a clump of algae reveals polyps, stomachs with limbs, limbs with buds, buds with poison cells. This animal reproduces by buds, which we watch close up in time-lapse images. In another kind of jellyfish, the buds grow inside then live outside for a few days until being on their own.
Les danseuses de mer
Two kinds of starfish, the brittle and the feather. The brittle star moves its arms alone, without the aid of suckers. Underneath is a single opening. Stalks move food close to the mouth and move waste away. We see vents, used in reproduction and breathing. We watch the hatched young expelled into the water.
Oursins
Underwater photography, magnified close-ups, and film through microscope present the sea urchin, a complex creature. We see their mouth and five teeth close and open. After injecting one with gelatin, the shell is removed and we see the muscle structure, digestive tube, and reproductive organs.
