Hello all.
First, sorry for my poor English. I'm from Brazil and I can say that here we have both situations. I can not scale that has more on which side. Because it's forbidden to be a "reptile keeper" here in this country (we can only keep Bcc and 2 sp corallus and 1 epicrates), we all have to be "hidden" from the authorities, and do our best to preserve the species, since there are a lot of deforestation and habitat loss and no one in government cares about is what sp kind disappearing or being damaged. It's up to some of us do this work, and still, run the risk of being labeled criminals
About trade, there's a large "black market" (dont know how to say these words in this language). But let's say that most keeps the animals at home in good condition, and just going copulation, and consequently, the sale or exchange.
