海洋尖尾藻是一种异养甲藻，在三维环境中以螺旋形路径游动。它还对各种环境刺激做出反应，并广泛观察到其游泳模式的变化。了解这种游泳行为并提供量化游泳相关参数的工具将有助于解释其对环境刺激的反应，包括食物和化学线索的存在。我们回顾了文献分析游泳在O。码头我们还概述了随机行走，路径分析和模拟的个人为基础的运动相关领域的O。码头然后，我们讨论了一些相关的问题，试图通过分析二维（2D）视频显微镜数据来了解三维螺旋运动。我们强调，目前的模型在文献中不能准确地模拟螺旋行走，并得出结论，O。Marina将是建立标准3D框架的合适候选者，该框架可用作未来表征观察到的运动模式的工具。
Oxyrrhis marina is a heterotrophic dinoflagellate that swims in helical paths in a three-dimensional (3D) environment. It is also known to react to various environmental stimuli and resultant changes in its swimming patterns have been widely observed. Understanding this swimming behaviour and providing tools for quantifying swimming-related parameters will aid in interpreting its response to environmental stimuli, including the presence of food items and chemical cues. We review the literature on the analysis of swimming in O. marina. We also outline the related fields of random walks, path analysis and simulation of individual-based movement where relevant to O. marina. We then discuss some of the problems associated with trying to understand 3D helical movement through analysis of two-dimensional (2D) video microscopy data. We emphasize that the current models in the literature cannot accurately simulate helical walks and conclude that O. marina would be a suitable candidate for establishing a standard 3D framework that can be used as a tool to characterize observed movement patterns in the future.
