Description

Swimming behaviors of four species of cnidarian hydromedusae (Aequorea victoria, Mitrocoma cellularia, Stomotoca atra, Aglantha digitale) exposed to two flow conditions in a laboratory turbulence generator - still water and turbulent (ε ~10-7 m2 s-3).

Methods & Sampling

Dataset acquisition description

The x and z position of the most aboral point on the bell were digitized in ImageJ (NIH, Bethesda, Maryland, USA) at 1-s intervals to produce trajectories from a total of 82 individual hydromedusae from 34 tank trials. Resultant data don’t agree well with in situ measurements suggesting that there may have been tank artifacts.

Measured swimming parameters from each individual hydromedusa included depth in the tank, observed speed, acceleration, the net-to-gross displacement ratio (NGDR), time spent swimming and swimming direction.
