Reviewer 1 Report
Comments and Suggestions for AuthorsThe authors present a novel method for estimating body length of crocodylians from drone imagery that has the potential to better inform management and conservation of these cryptic species. In particular, the authors should be commended for their thorough description of this methodology, the analysis used to verify its accuracy for a variety of species and imagery, and discussion of the limitations of the method. All this contributes to ensuring the method can be reproduce and used to full effect by researchers and conservation managers under wide range of circumstances. I therefore recommend this article be published with minor revisions, which I have outlined for the authors in the 'specific comments' section of the attached document.

Reviewer 2 Report
Comments and Suggestions for AuthorsThe manuscript showed interesting results about crocodile’s allometry research and images obtained by UAVs; it is innovative and presents original results. I found minor errors throughout the manuscript; however some of them must be reviewed. I attached a review detail.
