Explore the wonderfully bizarre life of the sea cucumber, and discover the essential role they play in keeping ocean ecosystems healthy.
Is it a fuzzy sock? An overripe banana? A moldy tube of toothpaste? No! In fact, it’s a humble sea cucumber: a brainless, fleshy form surrounding a digestive tract, and bookended by a mouth and an anus. And while it might look odd, its daily toil paves the way for entire ecosystems to thrive. Cella Wright journeys to the bottom of the ocean to explore the lives of these sausage-shaped wonders.
Lesson by Cella Wright, directed by Guto BR, Flávia Godoy and Lívia Serri Francoio.
