Fast evolving 18S rRNA sequences from Solenogastres (Mollusca) resist standard PCR amplification and give new insights into mollusk substitution rate heterogeneity.
(2006) isolated two Gbx genes in Solenogastres and the cephalopod Nautilus pompilius.
At the bathyal level, the other dominant organisms are in the following order: amphipods, isopods, and tanaidacian crustaceans; in the abyssal plains, tanaidacians, bivalves, and isopods; in the oceanic trenches, bivalves, solenogastres (Aplacophora), acorn worms (Enteropneusta), bryozoans, tanaidacians, and spoon worms (Echiurida).
The cylindrical, vermiform, sclerite-covered Aplacophora has been a perplexing taxon of molluscs ever since the first two species, representatives of the only two clades, were discovered: Chaetoderma nitidulum Loven, 1844, Caudofoveata (=Chaetodermomorpha Pelseneer) and Neomenia carinata Tullberg, 1875, Solenogastres (=Neomeniomorpha Pelseneer).
Gastropoda: Prosobranchiata: Rhipidoglossa, Docoglossa, Tectibranchiata, Polyplacophora, Solenogastres, Scaphopoda.
Aplacophoran molluscs are a small taxon with fewer than 400 described species including both neomenioids (Neomeniomorpha or Solenogastres) and the chaetoderms (Chaetodermomorpha or Caudofoveata).
The second pathway involves a pericalymma larva (= test-cell larva) and is found among protobranch bivalves and neomeniomorphs (= solenogastres) (Fig.
Solenogastres has a simpler neural organization in the head region, being regarded as primitive (Scheltema, 1993, 1996), although opposing views have been offered (Salvini-Plawen, 1985; Salvini-Plawen and Steiner, 1996).
Neomenioid aplacophorans (= Solenogastres) are shell-less vermiform molluscs with a ciliated foot and an epidermal cuticle covered by many calcareous spicules.
