U.S. Bufo marinus vs. Suriname

[n321]

So I've been seeing more of these Suriname Giant Toads for sale online. Are these genetically different from the ones here in the U.S.? Has anyone ever had a marine toad from the U.S. that grew larger than 7"?

I guess I'm just wondering what the difference is really...

The only difference is where they live, they are still the same species. I have read OPINIONS that say Suriname are larger and to get those. But from what i understand there are no differences in genetics. The largest cane toads ever recorded was found in Australia the largest one on record was 15" vent to snout. that is where mine are from however my female is only pushing 7" she is still very young and growing. I have also read a Cane toad caught out of Hawaii was 12" vent to snout. I think what they eat in different locations may have an impact on size. But there is really no substantial evidence proving the Cane/marine/suriname toad size difference. there is a site online that sells cane toad adults and marine toad adults listed separately. I emailed them and asked what the difference was. they told me the only difference is the size they are wild caught from the same area. even though you may have a 4" toad it can still be sexually mature and be considered an adult. but even if they are adults they still keep growing. with that said they sold adult cane toads 3-4" in length and the marine toad listing was the exact same species at 8-10" in length. I would love to see more research on this topic. Just like you I want solid facts not opinions.

Yeah I know there's been work on the phylogeny of the species. Here's one article:
Phylogeography of Bufo marinus from its natural and introduced ranges

I'd be curious if there is anything genetically that makes the toads larger or smaller...
