How do you take the nose prints? Do you tranquilize them and then literally press their nose against a piece of paper covered in an inklike material or is it photo based?
I don't know if Gorillas work the same way as dogs, but maybe you could put something that smells nice on a device that extends a small nose-boop extractor arm when close, and gather the noseprint that way.
To simulate this invention:
- have a dog
- put something smelly on your thumb
- extend arm to point thumb towards dog
- as the dog is within 5-10cm radius of your thumb, press your thumb against their nose (and say the obligatory "boop")
- imagine your had something to extract noseprints from their nose on your thumb
