Short summary
Sedimented hydrothermal vents are among the least studied deep-sea ecosystems. We compared food webs between hydrothermally active and off-vent areas of the Bransfield Strait, Antarctica. Invertebrates showed diverse feeding strategies and occupied different positions in food webs between vent and non-vent sites. Feeding and microbial diversity was lowest at vent sites. Chemosynthetic organic matter was a minimal food source at both vents and non-vents.
