Knowledge of relationships between predator size and prey are needed to describe interactions species classes in food webs. Most estimates sizes have been based on dietary studies apply small numbers a relatively narrow range. These may or not be representative values for other groups body locations. Marine data associated with published literature were identified collated produce single set. If length mass measured the original study, was calculated using length–mass relationships. The set consists 34 931 records from 27 locations covering wide range environmental conditions tropics poles 93 types ranging 0.1 mg over 415 kg 174 75 pg 4.5 kg. Each record includes: scientific names, common taxa, life stages (length conversion details), plus type feeding interaction, geographic location (with habitat description, latitude, longitude) mean annual (sea surface temperature primary productivity).
