Eighteen different rotifers were found at varying densities, depths and locations in the interstitial sand of a small, brackish-water Floridian beach. Most of the rotifers encountered were found in greatest numbers two meters from the waters edge, corresponding to the high-tide mark of the sampled beach. A single, dead Notholca (Pseudonotholca) japonnica kisselevi Kutikova (1970), previously known only from its original description locality in the south Kuril islands, Sea of Okhotsk, was found in the 6 cm depth core at mid-tide level.
