Okay, to start, I didn't know where to put this because it isn't really directed at chameleons... I'm all for keeping WC in the cases of breeding to increase/make possible CB populations of animals. Crabs are the main animal that got me thinking... I've really wanted a land crab(patriot and/or vampire crabs to be exact) I always found crustaceans to be among the coolest inverts. Something that bothers me is that I believe many of these types almost have to be WC and are near impossible to breed in captivity. I feel like keeping them as pets does nothing good for them as much as I'd love to get some. Would there be any positives to keeping them as far as the species goes? Or maybe breeding is umm slightly possible and could make for a fun/big project, idk?
BTW this doesn't only refer to crabs, but to any animal that is in a similar situation with breeding difficulties.
I wanted to hear some thoughts on the matter, ATM I'm uncertain how to feel so I figured I'd get some feedback from the wise people at CF!
I personally think it depends on the animal.
Obviously I am ok with crabs since I have them. They are massively prolific breeders since only a tiny percentage live to adulthood-they are the food source for countless animals and that is their primary niche (along with scavenging). A wild crab lives in fear 24/7 and just tries to survive long enough to breed. Whereas in captivity, while many are ill-treated, there are those such as mine which live long lives without fear in an environment very close to ideal.
On the other hand, I am old enough to remember quarantine stations and imported parrots. This was an absolute travesty, adult birds trapped, packed by the hundreds in cages with the ones on the bottom suffocating. These are extremely intelligent animals (sorry, hermies..) These animals have only one to three offspring usually, so the trapping had a real impact on their wild populations, and I think each and every one suffered for the rest of its life. In some cases that was not very long as some never could cope with being caged and lived in a constant state of immunosuppression.
But of course we did have to bring in adults to be able to establish the stable populations of captive bred parrots that we are now fortunate enough to have.
And to those who say even captive parrots/frogs/lizards etc. should not be kept, I always point out that a wild animal faces these things on a daily basis:
Constant fear of predation
Starvation, dehydration or inadequate nutrition including die-offs because of this
Pervasive Internal and external parasites
Exposure to severe weather conditions
It is a very good question, and I am not sure there is an answer, except to support captive breeding when and wherever that is possible, and when it is not, provide the very best conditions for the animals you keep.
