Saltie with an orangutan.

Some of the comments are suggesting it's a proboscis monkey, since the nose flap seems to be visible at one point. Either way, really cool finding. And it's a juvenile croc too!

I noticed the nose now. Makes sense in hindsight. Don't think a juvenile croc would be that much bigger than an adult orang.

I'm ashamed I didn't post this earlier.

A second reported instance of crocodile predation on a rhinoceros is presented in Capstick (1977). This attack was witnessed by a group of vehicle-bound tourists photographing wildlife at a waterhole "in a Tanzanian game park during the late 1950s". As described by Capstick (1977), a Nile crocodile estimated to be 14' long (4.2 m) "exploded from the water" and seized the rostrum of a 4000 lb (1814 kg) female Black rhinoceros as it lowered its head to drink. The initial phase of the struggle is described as a "test of strength" between the two animals; the rhinoceros strained to back away from the waterhole while the crocodile attempted to draw the rhinoceros into deeper water. Neither animal was able to move for almost an hour, but eventually the rhinoceros began "inching into the water". Thirty minutes later when its head was pulled beneath the water, the rhinoceros "rolled over in a fi nal fl urry" and drowned. Presumably the crocodile then began feeding on the carcass, although no further detail is provided.

Crocodilians have really skewed sex ratios.

The sex ratio of alligators and crocodiles is strongly biased towards females, often as high as 10 females to 1 male. Skewed sex ratios (that is, ratios other than 1:1) are commonly found in species exhibiting environmental sex determination.

Urban ranch often makes jokes but according to him he was given a dwarf caiman because it kept kill the other caimans, including females larger than himself.



The aggression chart notes the dwarf caimans are very aggressive by crocodilian standards so that does seem to indicate that dwarf caimans are a lot scrappier at parity than many other caiman species.

A rather informal paper but it notes that there are several documented accounts of mugger crocodiles preying on leopards.
