The first information about this species, under the name "Lepetodrilus n. sp.", was published on 3 January 2012.[1]
Distribution
editThis species is known from two sites near hydrothermal vents in the East Scotia Ridge: from 2,394 m depth at the E9 vent site, and from 2,608 m depth at the E2 site.[1]
Description
editPhylogenetic analysis of the mitochondrial cytochrome-c oxidase I (COI) gene of this limpet (GenBank accession number JN628254) and a range of other Lepetodrilus species, using Bayesian inference, places this species from East Scotia Ridge as a sister taxon to Lepetodrilus atlanticus, with a sequence divergence from this species of 5.48%.[1] This level of genetic divergence is consistent with that found between Lepetodrilus species within complexes of sister taxa, where interspecific distances of between 3% and 15% have been observed.[1]
Ecology
edit
This species is ubiquitous in low-temperature diffuse flow, being found on bare rock, sulphides, Kiwa sp., gastropods Gigantopelta chessoia, and stalked barnacles.[1] On the carapace of Kiwa n. sp., a "halo" of pale colouration surrounding the limpets indicates where this species of Lepetodrilus is grazing epizoic microbes.[1]
The population density of Lepetodrilus sp. on the barnacles Vulcanolepas scotiaensis was estimated to 20,172–56,904 individuals m−2.[2][3]
