Abstract

A new combination of the “rhizarian rider” phenomenon was observed in the sea area affected by the Kuroshio current, off Japan: a female of Brachyscelus crusculum (Crustacea, Amphipoda, Brachyscelidae) holding a colony of Odontosphaera sp. (Radiolaria, Collodaria, Collosphaeridae). The “rhizarian rider” phenomenon of Collosphaeridae and B. crusculum was first recorded. The large colony size (ca. 13 mm) and color (pale blue) of Odontosphaera sp. are also newly reported by this study. Brachyscelus crusculum presumably utilizes Odontosphaera sp. as a float, food source, and breeding bed.

“根瘤菌骑士”现象，Brachyscelus crusculum Bate, 1861（甲壳纲，Amphipoda, Brachyscelidae）和Odontosphaera sp. （Radiolaria, Collodaria, collosphaidae）的新组合。

在日本外海受黑潮影响的海域，发现了一种新的“根瘤菌骑手”现象：一只雌性腕足类（Brachyscelus crusculum，甲壳纲，Amphipoda，腕足科）抱着一群Odontosphaera sp. （Radiolaria, Collodaria, collosphaidae）。首次记录了胶球蝇科和白蚁的“根瘤菌骑士”现象。此外，本研究还报道了牙齿藻的大菌落（约13 mm）和颜色（淡蓝色）。据推测，Brachyscelus crusculum利用Odontosphaera sp.作为漂浮物、食物来源和繁殖床。
