Phylogenetic Position of Eurihaline Rotifer Brachionus sp. Originated From Tumpaan Waters, South Minahasa, North Sulawesi

This study aims to determine the phylogenetic position of rotifer Brachionus sp. sample originated from Tumpaan coastal water, North Sulawesi in tree spp. 27 samples selected 100 available NCBI Genbank. The phylogeny was constructed on basis COI (Cytochrome Oxidase I) gene sequences using MEGA7 software and neighbor-joining method. Results show that divided into 2 clades, group (closely related group) out-group (distantly group). It is confirmed originating Coastal Water within group, which has closely B. plicatilis complex BUS06 indicated by a bootstrap value 80%. belongs SS-type rotifers with an average body size 149±1.3 μm. been known as live prey for fish larvae mouth-opening 150
