Krakal is a beach in Gunungkidul, Yogyakarta, Indonesia which has white sand and coral substrate in the intertidal zone. Cypraeidae and Conidae are families of gastropods found quite varied in the intertidal zone of Krakal Beach. The purpose of this research was to discover the diversity of Cypraeidae and Conidae families in the intertidal zone of Krakal Beach, Gunungkidul, Yogyakarta. The research was conducted on May 24, 2014 and May 25, 2017. The ecological parameters recorded were  26,5oC for temperature in 2014 and  26oC for temperature in 2017 , ±3.35% for salinity in 2014 and ±3,6% for salinity in 2017, 7.7 for pH. in 2014 and 7 for pH in 2017. The samples were collected using purposive sampling method, and specimens were identified by determining the morphological characteristics of the shell.
