This paper was aimed to sedimentary environment appropriate for survival and inhabit of Saxidomus purpuratus juvenile. The sediment type in Goheung coast was dominated by silt (78.1 ± 0.6%), and followed by clay (20.2 ± 0.7%) and sand (1.7 ± 0.8%), and that in Hwagye coast was similar to that of Goheung coast (Silt 78.5 ± 0.7%, Clay 20.7 ± 0.6% and Sand 0.8 ± 0.4%). Thus the Saxidomus purpuratus juvenile habitat was mainly composed of silt. In case of Saxidomus purpuratus adult habitat, silt (79.6 ± 0.5%), and followed by clay (19.7 ± 0.5%) and sand (0.7 ± 0.3%). But, the research results, sedimentation environment showed the highest response rate (50%) as the environmental factors for juvenile survival. Sandy silty showed the highest response rate (83%) for the most appropriate sedimentation environment.
