The Halomonhystera disjuncta population is homogeneous across the Håkon Mosby mud volcano (Barents Sea) but is genetically differentiated from its shallow-water relatives
The deep sea has a high biodiversity and a characteristic bathyal fauna. Earlier evidence suggested that at least some shallow-water species invaded the ecosystem followed by radiation leading to endemic deep-sea lineages with a genetic and/or morphological similarity to their shallow-water counterp...

The deep sea has a high biodiversity and a characteristic bathyal fauna. Earlier evidence suggested that at least some shallow-water species invaded the ecosystem followed by radiation leading to endemic deep-sea lineages with a genetic and/or morphological similarity to their shallow-water counterparts. The nematode Halomonhystera disjuncta has been reported from shallow-water habitats and the deep sea [Håkon Mosby mud volcano (HMMV)], but the morphological features and the phylogenetic relationships between deep-sea and shallow-water representatives remain largely unknown. Furthermore, nothing is known about the genetic structure of the H. disjuncta population within the HMMV.
