Body size is a fundamental characteristic of animals that impacts every aspect of their biology from anatomical complexity to ecology. In Mollusca, Solenogastres has been considered important to understanding the group’s early evolution as most morphology-based

Although many of the most recently described Solenogastres (Mollusca, Aplacophora) come from abyssal locations (3500–6000 m depth), most members of the group have been described from the continental shelf and slope with just 23 of the 290 formally described

Five species of Solenogastres, order Pholidoskepia, from various Scandinavian collections are described and classified. Tegulaherpia celtica Caudwell, Jones & Killeen is synonymized with T myodoryata Salvini-Plawen, which is known from the Mediterranean

So far, of the 292 known species of solenogasters (Mollusca, Aplacophora), 62 belong to the clade Pholidoskepia Salvini-Plawen, 1978. Of these, only two have an abyssal distribution (3500–6000 m depth). Among Pholidoskepia, Dondersiidae Simroth, 1893

Although many of the most recently described Solenogastres (Mollusca, Aplacophora) come from abyssal locations (3500–6000 m depth), most members of the group have been described from the continental shelf and slope with just 23 of the 290 formally described

Solenogastres (Mollusca, Aplacophora) form a common part of the benthic malacofauna in the deep sea, but their diversity in the Northwest Pacific is poorly understood. In this study, we analyze the systematics and distribution of Solenogastres sampled

Although many of the most recently described Solenogastres (Mollusca, Aplacophora) come from abyssal locations (3500–6000 m depth), most members of the group have been described from the continental shelf and slope with just 23 of the 290 formally described
