Range Extension and Notes on the Habitat of the Isopod Munna halei Menzies

Abstract

The small asellote isopod Munna halei Menzies, 1952, was described from Tomales Point, Marin County, California, from under stones and in kelp (Macrocystis) holdfasts in the lowest intertidal zone (Menzies, 1952). It remained unknown elsewhere until Iverson (1974) reported it at El Capitan Beach, San Luis Obispo County, California, from among the spines of the purple sea urchin Strongylocentrotus purpuratus (Stimpson) from mid-intertidal rocks.
