Jaguar certainly don't seem particularly shy from challenging reasonably large caiman/crocodiles, even in the water.
Does anyone have any other examples?

I think that most of you have probably seen this infamous video.

If you were to rank the apex predators in the Amazon, I would list them as follows;
Terrestrial
Jaguar
Shallow water
1. Orinoco Crocodile
2. Black Caiman
3. Green Anaconda
Deep Water
Bull Shark

I wouldn't say those caiman are reasonably large, all of them appeared smaller than the Jaguar, even the one in the first video which at first glance appears bigger, at closer inspection only looks to be of comparable total length to the jaguar, at the 1:50 mark you can clearly see which of the two has the bigger torso and is the Jaguar. However, Cavalcanti & Gese (2010)recorded that almost 25% of Jaguar kills in the southern pantanal comprised of spectacled and yacare caimans and that their kill rate of those species peaked during the wet season, so yeah, water is no obstacle for them when it comes on preying on these species of caiman.
The spectacled caiman preys on adult male green anacondas and sometimes on big females, albeit no healthy ones, where will that put it in the list?

I would put the Spectacled caiman below the Green Anaconda. I would usually back the large snake over a crocodilian which averages less than 2 meters - but of course, it is above the Yellow Anaconda.

The largest caiman besides the black caiman don't get over 150lbs if even that.... that's not large at all compared to an average 220lb jag.

^reminds me of the famous video of a honey badger killing a Nile monitor, so many people were under the impression that honey bad her and lizard were the same size or the lizard was bigger, all of them too stupid to do some light reading and figure out that the no Varanid on the continent gets as heavy as honey badgers.

Those caiman are definetly smaller then the Jag. Anyway, Vodmeister, you may find this paper interesting:
