Supplementary information for sample collection, isotope values for individual Manta birostris and surface zooplankton tows, and mixing model summary statistics. from <i>Manta birostris</i>, predator of the deep? Insight into the diet of the giant manta ray through stable isotope analysis

Included here is a detailed sample collection protocol for obtaining M. birostris muscle tissue samples from free swimming animals. Additionally, the CN isotope values for individual Manta birostris and surface zooplankton tows are presented, along with mixing model summary statistics for the mean credible interval source contributions of surface zooplankton and mesopelagic sources to M. birostris diet.
