Sthenaster emmae Mah et al . 2010 Figure 17 A–D In situ images of this species were identified based on the distinctive arrangement of abactinal plates as well as the wide superomarginal interradial plates. This is contrasted with those in Gilbertaster which are more elongate. Color in life of this species is white on the disk surface with darker orange plates. Arms are a more solid colored light orange. A second morphotype, of what is interpreted as a smaller individual was a uniform pink-brown in color. New observations of this species in conjunction with the extensive survey observations of Okeanos Explorer throughout the Gulf of Mexico and adjacent regions show occurrence to be limited to the southeastern coastal region of North America, specifically, the Savannah Banks and Central Plateau Scarp region.
