Skin biopsies offer less invasive studies of the reproductive status of sharks

Researchers from the UAB have shown that sex hormones accumulate in the skin of sharks. This finding opens a new way for the evaluation of their reproductive status by the biopsy of a sample that can be taken remotely in their own environment. The researchers are committed to further use of this new method, as it is less invasive than others that require greater manipulation or the capture of the animals.
