Two new species and one new genus, collected by NOAA ship Okeanos Explorer, Bathyceramaster kelliottae n. sp. and Rhianastra isosceles n. gen., n. sp. (Goniasteridae; Asteroidea) are described from deep-sea settings in the North Atlantic. Two potentially undescribed species are observed from imagery and new in situ observations further elucidate life modes and feeding behavior of several species from North Atlantic deep-sea habitats. New occurrences of Atlantic Neomorphaster are presented and Neomorphaster forcipatus is synonymized with Neomorphaster margaritaceus.

Article Synopsis
- The North Pacific hosts many undiscovered species, particularly in deep-sea habitats below 200 m, with new findings primarily from in situ and museum collections.
- The Goniasteridae family, the most diverse group of starfish (Asteroidea), has led to the identification of one new genus and seven new species.
- Recent observations from research vessels R/V Nautilus and MBARI have enhanced understanding of goniasterid ecology and morphology in deep-sea environments.

Assessment of Antarctic taxonomic diversity for asteroids and other taxa for poorly studied or unknown regions, such as the deep-sea, will be important for our understanding of these understudied habitats. Eleven new species and a new genus are described from three families (Asterinidae, Goniasteridae, Solasteridae) within the Valvatida, nearly all of which were collected from deep-sea settings below 1000 m by the US Antarctic Research Program in the 1960s. A new subfamily, the Kampylasterinae subfam.

Between 2015 and 2018, the NOAA ship Okeanos Explorer embarked on the CAPSTONE expedition, that collected video and specimen data from the Hawaiian Islands region and other American territories in the Central and South Pacific Ocean. Ultimately 20 species, 12 of which are newly described, from 14 genera in 3 families are described herein with one further undescribed species of Pythonaster currently in preparation. Okeanos Explorer collected a total of 17 sea star specimens, of which 9 represent new species and 4 new genera.
