Not only morphs are expensive, many species uncommon in the pet trade also demand a high price. One reason the US's herps are so cheap is that they are bred in such heavy quantities that there is just a massive supply for buyers. Another reason would be that the US, as with most other countries, allows collecting and importing/exporting of herps.
I assume based on population (~20 vs ~350million) that there are a lot more people interested in the husbandry and breeding aspect of herp keeping. Therefore, we can assume that many more people own herps and potentially breed herps. Especially when you take into considering how easy it is to obtain herps in the states.
I do not fully agree with the herp ownership laws in the US, but I also do not completely agree with the AUS laws either. Criticizing American hobbyists is absolute BS, you have no evidence to base your claims on. I was in the hobby overseas for years, both keeping and breeding, until I moved overseas. How can you guys criticize what you have not experienced?
I think the only valid thing said in this thread is that having cheaper herps encourages "replacement" rather than a vet trip.
Also,
the hobby is much older in the states, especially with morphs, and therefore the causes a difference in prices. Common and "normal" herps will be priced much lower then the freaks.
But yes, we can get herps for a couple of bucks at an expo. But then again, there is no shortage or herps selling for thousands of dollars.
Examples:
BHP's cost more then Womas, over 1K for a hatchling.
Diamond Pythons cost more then Jungle Carpet Pythons, 1K vs. $100.
Shinglebacks cost a few grand a piece as hatchlings. As do many Egernia sp.
The US also can't get many species that we have the liberty to keep, many geckos, skinks, and monitors because of Au's import/export laws.
Try Kingsnake . com to see US herp prices & quantities. It may shock you how many are actually available and how much they are actually selling for.
