2nd animal
 



 
Herviella mietta
Marcus & Burch, 1965
 
Herviella mietta
Maximum size:  40 mm (Kay, 1979).

Identification:  This is a distinctive, dusky gray to black animal.

Natural history:  Herviella mietta is a rare species on Maui. We've only seen one animal found in a tide pool at a moderately exposed site. It's nocturnal and, unlike most members of the family, feeds on a sea anemone: Anthopleura nigrescens (Rosens, 1969). (Note 1)

Distribution:  Maui and Oahu: widely distributed in the western & central Pacific.

Taxonomic notes:  It was first reported from Hawaii in Rosin, 1969 (as Herviella sp.).

Photo:  PF: found by Darcy Kehler; Napili Bay, Maui; May 21, 1997.

Observations and comments:

Note 1:  Although the Maui animal was found at night, the Oahu animal found by Brian Magnier was reported as "Exposed on rock in tide pool, mid-day" (pers. com.).
