| Research Abstract |
This study showed the ecological relationship among Dinophysis, ciliate, and cryptophyte in Japanese coastal areas. Many Dinophysis species ingested the ciliate Myrionecta rubra, and further the ciliate preferentially ingested the cryptophyte Teleaulax amphioxeia. We also revealed that Dinophysis mitra retained more than 100 kinds of plastids robbed from algal prey.
