The Hippasterinae is a subfamily within the Goniasteridae, consisting of five genera and 26 species, which occur in cold-water settings ranging from subtidal to abyssal depths. All known genera were included in a cladistic analysis resulting in two most parsimonious trees, supporting the Hippasterinae as monophyletic. Our review supports Sthenaster emmae gen. etsp. nov. as a new genus and species from the tropical Atlantic and two new Evoplosoma species, Evoplosoma claguei sp. nov. and… 

Two new deepwater sea anemones (Cnidaria: Anthozoa: Actiniaria) Sicyonis heliodiscus sp.n. (Actinostolidae) and Hormathia pacifica sp.n. (Hormathiidae) from Pacific

New species and global revision of Hippasteria (Hippasterinae: Goniasteridae; Asteroidea; Echinodermata)

Three new species of Hippasteria, rooted against Evoplosoma, are described from deep-water settings, and discussions about biogeography, cladogenic events, and morphology are presented.

Molecular phylogeny of the Valvatacea (Asteroidea: Echinodermata)

A comprehensively sampled, three-gene molecular phylogenetic analysis of the Valvatacea is presented, suggesting that Antarctic valvataceans may be derived from sister taxa in adjacent regions.

Global Diversity and Phylogeny of the Asteroidea (Echinodermata)

Diversity and phylogeny as they have figured into the evolution of the Asteroidea from Paleozoic to the living fauna is presented, as well as brief notes on broader significance, ecology, and functional morphology of each.

Biology of deep-water octocorals.

Global population divergence of the sea star Hippasteria phrygiana corresponds to the onset of the last glacial period of the Pleistocene

Coalescent simulations suggested that the three regions have been diverging with little or no gene flow for the past 50–75,000 years, a time frame that corresponds to the onset of the last glacial period of the Pleistocene.

The Sea Stars ( Echinodermata : Asteroidea ) :

  • Environmental Science
  • 2018
The Sea stars (Asteroidea: Echinodermata) are comprising of a large and diverse groups of sessile marine invertebrates having seven extant orders such as Brisingida, Forcipulatida, Notomyotida,



Systematics, phylogeny and historical biogeography of the Pentagonaster clade (Asteroidea: Valvatida: Goniasteridae)

One specific ingroup lineage, including Tosia and Pentagonaster, attains a much larger adult size than those of its sister-taxa, suggesting that Cope’s rule may apply to asteroids within this clade.

Phylogeny of the Zoroasteridae (Zorocallina; Forcipulatida): evolutionary events in deep-sea Asteroidea displaying Palaeozoic features

Phylogenetic results suggest that the morphololgical resemblance between zoroasterids and Palaeozoic taxa, such as Calliasterella, is convergent but a paraphyletic Zoroasteride cannot be rejected and remains consistent with basal crown-group affinities.

Reproductive isolation among morphotypes of the Atlantic seastar species Zoroaster fulgens (Asteroidea: Echinodermata)

This study investigates the genetic divergence between morphotypes of Z. fulgens using sections of the cytochrome oxidase 1 (COI) and 16S regions of the mitochondrial genome to investigate the evolution of slope species.

New distribution and host record for the starfish parasite Dendrogaster (Crustacea: Ascothoracida)

The description of an intracoelomic parasite of the genus Dendrogaster, the largest ever reported, collected for the first time from the starfish Hippasteria phrygiana in the deep waters of the St Lawrence Estuary (eastern Canada), is presented.

The fauna associated with the bank-forming deepwater coral Lophelia pertusa (Scleractinaria) on the Faroe shelf

The associated fauna of this branching deep-water coral was as rich and diverse as that of hermatypic branching species of coral and 97 species are recorded for the first time from the area around the Faroes.

Pleistocene speciation of sister taxa in a North Pacific clade of brooding sea stars (Leptasterias)

Estimates of population splitting times for two of the pairs of putative sister taxa were obtained by a multilocus coalescent analysis and estimates of mitochondrial mutation rates were approximately 50% of the values calibrated for sister species pairs in tropical sea stars and sea urchins.

Deep water bioherms of the scleractinian coral Lophelia pertusa (L.) at 64° n on the Norwegian shelf: Structure and associated megafauna

Abstract Megafauna on bioherms (large biological structures) of the scleractinian coral Lophelia pertusa at 240-290 m depth in the Haltenbanken- Fmyabanken area was investigated by video-recording.

Megafauna associations with deepwater corals (Primnoa spp.) in the Gulf of Alaska

Deepwater corals (Primnoa spp.) observed from a manned submersible at 11 sites in the Gulf of Alaska from 1989 to 1997 indicate Primnoa are important components of the deepwater ecosystem and removal of these slow-growing corals could cause long-term changes in associated megafauna.
