Herviella mietta Marcus & Burch, 1965
|Maximum size: 40 mm (Kay,
This is a distinctive, dusky gray to black animal.
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)
Maui and Oahu: widely distributed in the western & central Pacific.
It was first reported from Hawaii in Rosin, 1969 (as Herviella sp.).
found by Darcy Kehler; Napili Bay, Maui; May 21, 1997.
Observations and comments:
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.).
