In all cases, the volume of the chambers was found large enough to allow spontaneous fish movements. Clams and mussels the size of dinner plates were scattered along the base of six-foot high tube worms, which were decorated with bright red plumes. Stomach‐content analyses of the most abundant predators found at vents indicated that the zoarcid fish (Thermarces cerberus) primarily feeds on the vent snail Cyathermia naticoides, the limpet Lepetodrilus elevatus, and the amphipod crustacean Ventiella sulfuris, the very species that showed the greatest increase following predator exclusion.
