我们描述了Idionectes vortex gen. nov., sp. nov.，一种单细胞微真核生物，通过其表面的连续反转来游泳，类似于旋涡环。这种以前未被报道过的运动模式近似于一个被称为“环形游泳者”的假设概念，即一个甜甜圈形状的物体围绕其圆轴旋转，并沿着与其外表面运动相反的方向运动。在游泳过程中，Idionectes鞭毛相对于其细胞体旋转，这通常是原核生物而不是真核生物鞭毛的标志。
We describe Idionectes vortex gen. nov., sp. nov., a unicellular microeukaryote that swims by continuous inversion of its surface, similar to a vortex ring. This previously unreported mode of motility approximates a hypothetical concept called the 'toroidal swimmer', in which a doughnut-shaped object rotates around its circular axis and travels in the opposite direction to its outer surface motion. During swimming, the flagellum of Idionectes rotates relative to its cell body, which is normally a hallmark of prokaryotic rather than eukaryotic flagella.
