深海覆盖了90%以上的海底。然而，对深海生物-特别是原生动物-的了解很少，在那里发现的许多物种可能仍然没有描述。在Sporades盆地（地中海）取样期间，在1 230米深处的沉积物中发现了一种新的特殊原生动物物种。sporadica gen. nov. et sp. nov.是一种小型原生生物，细胞体长度在3.0和4.4 μ m之间，具有两个轴向细胞附属物和两个特征性的侧臂，它们几乎可以进行连续的划船运动。其形态不同于其它任何一个高阶分类单元，因此，该新属被分类为Protista incertae sedis。
The deep sea covers more than 90% of the ocean floor. Nevertheless, the knowledge of deep sea organisms - especially of protozoa - is scarce and many species found there are probably still undescribed. During sampling in the Sporades Basin (Mediterranean Sea), a new extraordinary protozoan species was found in sediments at a depth of 1,230 m. Meteora sporadica gen. nov. et sp. nov. is a small (cell body length between 3.0 and 4.4 mum) protist possessing two axial cell appendages and two characteristic lateral arms which perform almost continual rowing movements. Its morphology is unlike that of any other higher order taxon. Therefore, the new genus was classified as Protista incertae sedis.
