• The distribution, type, quantity and biosynthesis of acid mucopolysaccharide (AMPS) in embryos of the horseshoe crab (Chelicerata, Arthropoda) were examined. In embryos at early developmental stages, most of the AMPS is sulfated type and fills in the perivitelline space between the chorion and the blastoderm. It is already found in unfertilized eggs and it is rarely synthesized after fertilization. When the germ disc appears (stage 7), it is separated from the blastoderm by the secretion of a membrane. It disperses into sea water after the rupture of the chorion (stage 18 or 19). The other type of AMPS is synthesized in the embryonic body and is non-sulfated. At the hatching stage (stage 21), the non-sulfated AMPS decreases and sulfated AMPS is found in the endoskeleton, the intestine and in the articulation of the appendages.
