Abstract The habitat utilization by <I>Halichoeres tenuispinni</I>s and <I>Stethojulis in-terrupta terina</I> (Labridae) on a rocky reef at Izu Ocean Park, the east coast of Izu Peninsula, Japan is described. A total of 17 labrid species was observed by monthly observations from August, 2000 to August, 2001. <I>H. tenuispinnis</I> and <I>S. i. terina</I> were abundant, comprising 54% and 23% of the 3, 464 labrid sightings, re-spectively. Both species occurred equally over areas of boulders, rocky flat, rocky slope, rocky-sand and sand. However, observations on feeding behavior revealed significant differences between the species in their utilization of microhabitats on each bottom condition.
