Abstract. A heterosexual pair of hermit crab-associated alpheid shrimp Aretopsis amabilis De Man, 1910 was found inside the empty shell of burrowing spatangid sea urchin of the genus Platybrissus. The finding and ecology as well as possibility of social monogamy in this shrimp species are discussed.
