Description

Raw capture efficiency data of scyphomedusae from video analysis.

Methods & Sampling

Dataset acquisition description

Medusae were video recorded with different prey assemblages. Video was analyzed by identifying encounters (defined as prey entering encounter zone occupied by tentacles) and recording the outcome of each encounter.

Data Processing Description

Dataset Processing Description

BCO-DMO Data Processing Notes:

-Combined multiple tables of data into one.
-"Cnidaria_species" column was added.
-"retention efficiency" and "size" columns were removed because they contained no data.
-"nd" added to blank cells.
