Time-to-event data of four freshwater snail species predation by a prawn and a crayfish

Time-to-event data of four freshwater snail species - Thiara scabra, Tarebia granifera, Melanoides tuberculata and haita acuta - predation by a Macrobrachium rosenbergii prawn and a Cherax quadricarinatus crayfish. Predation was on five snails from each species. Snails were of the same size grade, as were the predators. The animals were fed during the experiment to ensure that predation was due to choice and not starvation.
The data includes the predator species (Mr for M. rosenbergii, Cq for C. quadricarinatus) and ID, predator body mass in g, the container code, the snail species and ID and time until snail predation in hours. "Cont" is short for control tank, which did not have any predator, and had only snails to account for background mortality.
