Vulcanolepas osheai, commonly referred to as O'Shea's vent barnacle, is a stalked barnacle of the family Neolepadidae. This species is endemic to New Zealand.
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). [1] The barnacle is found at depths of 1290 to 1500 meters in depth around hydrothermal vents and active underwater volcanoes. [1]
Vulcanolepas osheai has a peduncle (stalk) to capitulum (shell-casing) ratio of 5:1. [1] [3] 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. [1] The peduncle is composed of many rows of small scales (less than 1 millimeter), usually twice as long as wide. [1] [3] In larger specimens, more than 100 rows of scales have been observed. [1] The cirral setae of Vulcanolepas osheai are associated with filamentous bacterial epibionts, of the phylum Pseudomonadota (formerly Proteobacteria), although they are not endosymbiotic bacteria. [4]
Isotopic analysis have suggested these barnacles feed on sulphur-oxidizing bacteria, or other planktonic larvae that feed on sulphur-oxidizing bacteria around the vents. [4]
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. [1]
Barnacles are a type of arthropod constituting the subclass Cirripedia in the subphylum Crustacea, and are hence related to crabs and lobsters. Barnacles are exclusively marine, and tend to live in shallow and tidal waters, typically in erosive settings. Around 1,000 barnacle species are currently known.
Goose barnacles, also called stalked barnacles or gooseneck barnacles, are filter-feeding crustaceans that live attached to hard surfaces of rocks and flotsam in the ocean intertidal zone. Goose barnacles formerly made up the taxonomic order Pedunculata, but research has resulted in the classification of stalked barnacles within multiple orders of the infraclass Thoracica.
Gammaproteobacteria is a class of bacteria in the phylum Pseudomonadota. It contains about 250 genera, which makes it the most genus-rich taxon of the Prokaryotes. Several medically, ecologically, and scientifically important groups of bacteria belong to this class. It is composed by all Gram-negative microbes and is the most phylogenetically and physiologically diverse class of Proteobacteria.
The Brothers Seamount is a Pacific Ocean submarine volcano in the Kermadec Arc, 340 kilometres (210 mi) north east of New Zealand's Whakaari/White Island. It is one of the South Kermadec Ridge Seamounts.
Steve O'Shea is a marine biologist and environmentalist known for his research on giant squid.
Ifremeria nautilei is a species of large, deepwater hydrothermal vent sea snail, a marine gastropod mollusk in the family Provannidae, and the only species in the genus Ifremeria. This species lives in the South Pacific Ocean
The class Zetaproteobacteria is the sixth and most recently described class of the Pseudomonadota. Zetaproteobacteria can also refer to the group of organisms assigned to this class. The Zetaproteobacteria were originally represented by a single described species, Mariprofundus ferrooxydans, which is an iron-oxidizing neutrophilic chemolithoautotroph originally isolated from Kamaʻehuakanaloa Seamount in 1996 (post-eruption). Molecular cloning techniques focusing on the small subunit ribosomal RNA gene have also been used to identify a more diverse majority of the Zetaproteobacteria that have as yet been unculturable.
Lepas anserifera is a species of goose barnacle or stalked barnacle in the family Lepadidae. It lives attached to floating timber, ships' hulls and various sorts of flotsam.
Lepas anatifera, commonly known as the pelagic gooseneck barnacle or smooth gooseneck barnacle, is a species of barnacle in the family Lepadidae. These barnacles are found, often in large numbers, attached by their flexible stalks to floating timber, the hulls of ships, piers, pilings, seaweed, and various sorts of flotsam.
Pollicipes polymerus, commonly known as the gooseneck barnacle or leaf barnacle, is a species of stalked barnacle. It is found, often in great numbers, on rocky shores on the Pacific coasts of North America.
Bathymodiolus thermophilus is a species of large, deep water mussel, a marine bivalve mollusc in the family Mytilidae, the true mussels. The species was discovered at abyssal depths when submersible vehicles such as DSV Alvin began exploring the deep ocean. It occurs on the sea bed, often in great numbers, close to hydrothermal vents where hot, sulphur-rich water wells up through the floor of the Pacific Ocean.
Kiwa tyleri, the "Hoff crab", is a species of deep-sea squat lobster in the family Kiwaidae, which lives on hydrothermal vents near Antarctica. The crustacean was given its English nickname in 2010 by UK deep-sea scientists aboard the RRS James Cook, owing to resemblance between its dense covering of setae on the ventral surface of the exoskeleton and the hairy chest of the actor David Hasselhoff. The 2010 expedition to explore hydrothermal vents on the East Scotia Ridge was the second of three expeditions to the Southern Ocean by the UK led research consortium, ChEsSo.
Capitulum is a monotypic genus of sessile marine stalked barnacles. Capitulum mitella is the only species in the genus. It is commonly known as the Japanese goose barnacle or kamenote and is found on rocky shores in the Indo-Pacific region.
Paralepas minuta is a species of goose barnacle in the family Heteralepadidae.
Glyptelasma hamatum is a species of goose barnacle in the family Poecilasmatidae.
Conchoderma virgatum is a species of goose barnacle in the family Lepadidae. It is a pelagic species found in open water in most of the world's oceans attached to drifting objects or marine organisms.
The hydrothermal vent microbial community includes all unicellular organisms that live and reproduce in a chemically distinct area around hydrothermal vents. These include organisms in the microbial mat, free floating cells, or bacteria in an endosymbiotic relationship with animals. Chemolithoautotrophic bacteria derive nutrients and energy from the geological activity at Hydrothermal vents to fix carbon into organic forms. Viruses are also a part of the hydrothermal vent microbial community and their influence on the microbial ecology in these ecosystems is a burgeoning field of research.
Monowai Seamount is a volcanic seamount to the north of New Zealand. It is formed by a large caldera and a volcanic cone just south-southeast from the caldera. The volcanic cone rises to depths of up to 100 metres (330 ft) but its depth varies with ongoing volcanic activity, including sector collapses and the growth of lava domes. The seamount and its volcanism were discovered after 1877, but only in 1980 was it named "Monowai" after a research ship of the same name.
Kemp Caldera and Kemp Seamount form a submarine volcano south of the South Sandwich Islands, in a region where several seamounts are located. The seamount rises to a depth of 80 metres (260 ft) below sea level; the caldera has a diameter of 8.3 by 6.5 kilometres and reaches a depth of 1,600 metres (5,200 ft). The caldera contains several Hydrothermal vents, including white smokers and diffuse venting areas, which are host to chemolithotrophic ecological communities. The seamount and caldera, which were discovered by seafloor mapping in 2009, are part of the South Georgia and the South Sandwich Islands Marine Protected Area.
Pollicipes elegans, the Pacific goose barnacle, is a species of gooseneck barnacle inhabiting the tropical coastline of the eastern Pacific Ocean. Its habitat borders a close relative, Pollicipes polymerus, a gooseneck barnacle covering the coastline of the Pacific Northwest. Other species belonging to the genus Pollicipes are found along the eastern coastlines of the Atlantic Ocean.
