Diaulula greeleyi
(MacFarland, 1909)

Suborder: DORIDINA
Family: Dorididae


Western Atlantic from Brazil to Sth Carolina. East Pacific [Mexico, Costa Rica].


St. Joseph Bay, Florida, Florida, USA. Atlantic. Depth: less than 1 foot at low tide. Length: 3 inches. 9 April 2005. sandy bottomed sea grass meadow. Photographer: Mike Greenemeier

Large flat dorid with mantle covered in caryophyllidia, giving the back a furry appearance. Mantle yellow to yellowish brown with darker brown patching scattered all over, and some whitish patches around the mantle edge. Both the rhinophore and gill openings are surrounded by a high sheath. The gills are large but simple and unbranched. Underside bright yellow.

Camacho-Garcia & Valdés (2003) transfer this species from Peltodoris  to Diaulula and consider the East Pacific Peltodoris nayarita Ortea & Llera, 1981 to be a synonym, extending its distribution from the western Atlantic to the eastern Pacific.
