Diversity Of Crypthecodinium Spp. (Dinophyceae) From Okinawa Prefecture, Japan, Danang Ambar Prabowo, Ooshi Hiraishi, Shoichiro Suda

The genus Crypthecodinium (Dinophyceae) currently consists of only one species: C. cohnii, a heterotrophic marine dinoflagellate widely known able to produce prolific amount of DHA. However, previous studies revealed that there are morphological and genetic differences among Crypthedodinium cohnii-like strains, indicating the potential of undiscovered diversity of this dinoflagellate. Attempts of isolating heterotrophic marine dinoflagellate strains were made from submerged mangrove leaves and seaweed. A total of nine strains were established, cultured and maintained using seawater-based GTY medium for taxonomic identification and phylogenetic analyses based on SSU, ITS1, 5.8S, ITS2 and LSU rDNA. Morphological observation revealed all strains shared similar …

Coral-inhabiting gall crabs are either obligate symbionts or parasitic associates with their host corals. They form a variety of galls/pits inside the skeleton of living corals. Nine genera of gall crabs on several scleractinian corals were used to test the hypothesis that galls vary among cryptochirid genera. Phylogenetic and morphometric observations were combined to analyze the possible evolutionary significance of gall construction. A high degree of conservation of gall shapes was observed in relation to the gall crabs’ phylogeny. Gall/pit morphology and fidelity was studied in each of the different species of gall crabs. In addition, the correlation analysis results …
