Kind: research · Impact: low

## In brief

- A study maps defensive toxins in the cutaneous glands of the toad Rhinella icterica.
- The mapping uses optical coherence tomography and Raman microspectroscopy.
- The source provided only the title and feed listing, so no further findings are reported here.

## Why it matters

It demonstrates how optical coherence tomography and Raman microspectroscopy can be used to locate defensive toxins within toad skin glands, a method that may be relevant to studying chemical defenses in amphibians.
