Habitat
anomurans and Vulcanolepas''-like stalked barnacles) near East Scotia Ridge vents This species is a deep-sea stalked barnacle, found in the Brother's Caldera in the Havre Trough, near the North Island of New Zealand (approximately 700 kilometers off the coast of the Bay of Plenty). The barnacle is found at depths of 1290 to 1500 meters in depth around hydrothermal vents and active underwater volcanoes. == Description ==
Description
Vulcanolepas osheai has a peduncle (stalk) to capitulum (shell-casing) ratio of 5:1. The capitulum is made of approximately 8 calcareous plates, with a thin cuticle surrounding it, and is often stained black from manganiferous deposits due to the proximity to the hydrothermal vents. Isotopic analysis have suggested these barnacles feed on sulphur-oxidizing bacteria, or other planktonic larvae that feed on sulphur-oxidizing bacteria around the vents. == Etymology ==
Etymology
Vulcanolepas osheai is named after Dr. Steve O'Shea, who was curator of the National Institute of Water and Atmospheric Research in Wellington, New Zealand. ==References==
