Various data on morphology and ecology can be found below.

Trigonatus on the left, Palpebrosus on the right

Between the two, Trigonatus has a more elongated snout whilst Palpebrosus has more of a "bulldog" skull.

Both of these heavily armored caiman have an earth tone coloration that allows them to perfectly blend into their environment, as evidenced by these photos courtesy of Arkive

Here is some information from Fredrico Medem(1958) on the largest known individuals(at this time), behavior, and dietary habits

ignoring the maximum of 1.7m given for P.palpebrosus here, as it comes from a time before larger individuals were discovered (in the last decade), this is interesting stuff. Trigonatus appears to be less gregarious in the form of juvenile creches then Palpebrosus.

Very cool to see larger animals coming from the Pantanal.
