Facts about Eyeless Shrimp

1. 07

   Hydrothermal vent shrimp possess a unique farming behavior where they cultivate filamentous bacteria on their appendages and periodically consume them as their primary nutritional source.

   Eyeless shrimp at hydrothermal vents feed on chemosynthetic bacteria that derive energy from hydrogen sulfide rather than sunlight, forming the base of vent ecosystems.
