Southwest Pacific: endemic to New Zealand.
Are residents of intertidal zone with homing behavior (Ref. 32612) found in pools with rocks or boulders. May leave tide pools if aquatic conditions become inhospitable (Ref. 31184). Feed mostly on invertebrates, particularly crustaceans and mollusks. They breathe air when out of water (Ref. 31184) and swim with an eel-like motion (Ref. 9003). Eggs are guarded by the male parent (Ref. 205).
