Deep-Sea Spiders Feast on Methane: A Symbiotic Surprise
2025-06-23

Scientists have discovered three new species of sea spiders off the US West Coast that thrive on methane seeps thousands of feet below the surface. These spiders have a unique symbiotic relationship with bacteria living on their exoskeletons, converting methane into sugars and fats for the spiders to consume. This unprecedented nutritional strategy suggests these creatures may play a key role in preventing methane from reaching the atmosphere. The research highlights the importance of understanding deep-sea ecosystems for ocean sustainability and reveals intriguing details about their reproduction and microbiome inheritance.
