Description

High-resolution measurement of body displacement and angular position of individual appendages during escape swims of nauplii of the calanoid copepod, Bestiolina similis.

Methods & Sampling

Spontaneous escape swims were recorded at 5000 fps with an Olympus Industrial i-SPEED high-speed camera at 10x magnification through an inverted microscope (Olympus IX70). See publication for additional details.

Data Processing Description

Each video image in a swim sequence was converted into a bitmap (tiff format) and analyzed using ImageJ (Wayne Rasband rsbweb.nih.gov/ij/). Distance traveled from the initial rest point was calculate using Pythagorean theorem using X0, Xt and Y0, Yt coordinates. See publication for additional details.
