Assessing the biodiversity of coronates (Scyphozoa, Cnidaria) in Palau.

Jellyfishes have received more public attention due to the increase of described blooms. But these blooms aren’t yet fully understood and only a subset of the jellyfish are bloom-forming medusae. Research based on jellyfish should focus more on establishing present biodiversity. Traditionally, species are determined based on morphological features but these pose some limitations such as a limited amount of characteristics. As a response, the last decades molecular techniques have been increasingly used. Using a combination of factors increases the probability of proposing a likely hypothesis. In this study we focus on Coronatae (Scyphozao, Cnidaria) present in tropical Palau. Coronate familial relationships have been poorly resolved. Based on morphological characteristics and genetic data of the locus COI, 18S rDNA and 28S rDNA, the phylogenetic tree of Coronates was constructed. Here we describe a possible new family that wasn’t described before and the potential separation of the paraphyletic family Linuchidae into two distinct families. Additional information is necessaryto validate this claim. 4 out of 7 Coronate families are represented in Palau. Biodiversity is an important factor and related to the services of an ecosystem. Only by knowing the present biodiversity, an adequate management and conservation of ecosystems can be achieved.
