just wanted to see who keeps Palpebrosus and who keeps Trigonatus. from what i have read the Palpebrosus are smaller, and the Trigs are more aggressive. is this true? i have a chance to get a Trigonatus in trade for another animal, just wondering how the animals general size and behavior will compare to my brown caiman.

thanks in advance,

greg

In terms of min/max sizes, the trig gets a little larger, but the sizes certainly overlap and may not be significant.

I have never kept trigs, but the ones I have been associated with fit the mold you described.

Hi,

I keep a P. Trigonatus that is still quite young. Pretty much they are just how you described. They are quite spunky and dont like to be handled AT ALL. However, in my experience they are quite picky eaters when young, however, mine appears to be picking up in what it is willing to accept as a food item.

Chris,

I would have bet money that was photo was of a Palp. Are there any clear methods of differentiating between a palp and a trig? I particularly mean at the young stages.

I previously (incorrectly I suppose) thought the big brown spots on the jaw were reserved for the palp.

Mr. Fisher,

The clearest way of being able to differentiate between a P. Trigonatus and P. Palpabrosus are to look at the back plates. On the P. Trigonatus (like mine) the plates are scattered in no particular order, they are rather thrown all over the place. On the P. Palpabrosus, the boney plates are in a nice neat order in a perfect row.

Hope that helps,

Chris

I found a couple photos on naturecoastexotics website that you can use for a better differentiation. I know you can't really make out the plates on the back of mine due to the Dark photo.

Helps out immensely Chris. Thanks

Mr. F

Bill is correct, Trig's get a little bigger but in the overall scheme of things they are going to be in the same general size range. I have found both of these species difficult to deal with, much harder than your standard large crocodilian. They also don't do well in groups without alot of broken sightlines.

i see a lot of both palpebrosus and trigonatus sold as each other, and in my search for a good well started palp, i see alot of trigs. both are exceptional and awesome crocs deserving both good homes, and the respect that their larger cousins command. again, thanks for the quick replies and happy croc keeping!
