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.

本研究显示了日本沿海地区甲藻、纤毛虫和隐藻之间的生态关系。许多甲藻属的种类都对红色多囊藻有摄食作用，而且这些纤毛虫更倾向于对文昌鱼Teleaulax amphioxeia的摄食。我们还发现，甲藻mitra保留了100多种质体抢劫藻类猎物。
