Has anyone ever seen, heard, or possess any knowledge on this species? When I went o the Northern Berks Reptile show on 8/4, a vendor has 12 juveniles, along with cuvier's, schneider's, and american alligators for sale. Needless to say, these hybrid caimans caught my attention due to the fact that they resemble the pure spectacled caimans.......except they were $275 dollars ($150 more than the spectacled caimans). I had the chance to handle one and the vendor was very polite and hospitable, though the information he was given me.......he was definitely trying to throw me a sales pitch.........I also find it disconcerting that when I told him my location (New York, where it is illegal to keep them), he was still inclined to sell me one........... Anyways, to sum it up, the information he provided to me about the hybrid caimans were that the males would grow to roughly 5 feet and females roughly 4 feet with the maximum being 6 and 5 respectively. He also stated that the temperament of the caimans, despite the apparent claims that they are bred to be a pet is false, and that in order for them to be docile, they need repeated handling. He's stated that all of his caimans and alligators are eating and are handled routinely to ensure tractability and docility. Now don't get me wrong, I was VERY VERY VERY TEMPTED to buy one, especially since I was turning 22 in september, but needless to say, I did not get one due to New York City laws. However, the yacare caiman is known to reach up to 13 feet long and spectacled caimans 8 feet with the records of 10 feet long males being uncommon, but not rare. Jesus Rivas, herpetologist that works with the anacondas, has recorded several 3 meter long spec males killing anacondas in predation and defense. Therefore, this makes me wonder, do these hybrid caimans really stay the size of a cuvier's dwarf caiman and remain smaller than both parent species? Thanks for your time and sorry for the long post.
