This sea creature breathes through its butt - Cella Wright (2020x50)

: 30, 2020

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.
