Platydoris
sp. #3

 
Platydoris sp. #3
Maximum size:  90 mm.

Identification:  This is a firm, flattened dorid intricately blotched with cream and red-brown. The surface of the notum is finely granulose and the cream patches are irregularly elevated. (Note 1)

Natural history:  Platydoris sp. #3 is known from only two animals. The Oahu animal was dredged from about 100 m (328 ft). The French Frigate Shoals animal was found in a Halimeda kanaloana bed at scuba depths. When found, it was covered with a thin layer of sand.

Distribution:  Oahu and French Frigate Shoals.

Taxonomic notes:  This species bears some similarity to Platydoris inframaculata from elsewhere in the Indo-Pacific. It was first recorded in Hawaii from Oahu by Terry Gosliner.

Observations and comments:

Note 1:  Perhaps, the elevated cream patches are glands that produce mucus as an aid to movement through sand?
