【 摘 要 】

Horseshoe crab is an important component of macro-benthos communities in the fine sand or mud substrate in coastal waters, both in the tropical and temperate region. This primitive animal consists of four species in the world, and three species can be found di Asian region, including Indonesia, namely Tachypleus tridentatus, T. gigas, and Carcinoscorpius rotundicauda. Scientific information about species distribution of three Asian horseshoe crab in Indonesia is limited, also about morphometric characters. This study aims to determine the morphometric characters and species distribution of three Asian horseshoe crab in north coast of Java and south coast of Madura Island. This study was conducted on July-August 2016. The total number of three Asian horseshoe crab obtained in this study was 260 individuals, distributed along north coast of Java and south coast of Madura Island, respectively 176 individuals of C. rotundicauda, 35 individuals of T. Tridentatus, and 49 individuals of T. gigas. Tachypleus gigas has the largest size and widest class interval among three Asian horseshoe crab species. Morphometric characters is differences among three Asian horseshoe crab species. Carapace width and telson length were not significantly different among sampling locations only in T. Tridentatus.
