Biologie     Verklarende woordenlijst (bv. epibenthic)

Known only from the intertidal and subtidal waters of the Kermadec Islands, including Raoul Island and L’Esperance Rock. Most of the specimens collected using ichthyocides were from rock pools and from shallower subtidal areas (down to 9 meters) over rock and coral rubble. A single specimen has been observed and photographed at 28 meters in depth (Ref. 124119).
