New record of the wood-associated sea star Caymanostella , with notes on the phylogenetic position of the family Caymanostellidae (Asteroidea)
Abstract In 2016, three specimens of Caymanostella were collected from the Kuril-Kamchatka Trench area at depths of 5101–5134 m. Comparative morphological analysis revealed that the new specimens are similar to Caymanostella spinimarginata, the most geographically distant species (Atlantic Ocean). T...

Molecular evidence based on the analyses of three mitochondrial and two nuclear markers recovers the family Caymanostellidae as a sister-taxon to Ophidiasteridae (order Valvatida).
