Species composition of Discomedusae jellyfish (Scyphozoa) in the coastal waters of Eastern Surabaya, East Java

Abstract The Indo-Pacific is recognized as a hotspot for marine diversity. taxonomy of certain taxa, such Discomedusae jellyfish, has been neglected, despite its importance in the fishery industry. This study documents first records Java Sea using an integrative approach and provide notes about distribution area. We used up to 53 morphological meristic characters amplified one mitochondrial marker (COI). comparison assessment these data resulted recognition seven species Discomedusae, from which five recorded Two other require taxonomic revision confirm assignation. jellyfish coast might be correlated with life history species-specific ranges tolerance, not solely determined by environmental parameters. These findings foundations extending research area; description biodiversity will increase understanding population dynamics implications fisheries.
