Lugworms Unveil Universal Poop Coiling Rules
A Nature Communications study by Mehdi Habibi, Neil Ribe, and Daniel Bonn shows lugworms defecate against gravity and produce a constant-width poop coil that follows elastic rope-coiling physics, revealing universal patterns in fecal morphology and linking Darwin’s worm-focused work to broader functional morphology and soil fertility, with researchers even planning a second poop emoji for Unicode.
