This Worm's Gut Has No Way In or Out

The video explores unique animal adaptations, focusing on the giant tube worm Riftia pachyptila, which thrives in hydrothermal vent environments without a mouth or anus. These worms rely on symbiotic bacteria for nutrition through chemosynthesis, converting toxic chemicals into food. The bacteria enter the worms during their larval stage, and the worms manage waste through their bloodstream. The discovery of these worms has expanded our understanding of chemosynthetic ecosystems worldwide.
