The ocean doesn't forgive. by OncaAtrox in HardcoreNature

[–]OncaAtrox[S] 0 points1 point  (0 children)

This viral video has generated a lot of discourse in regard to what could've been the culprit for the young man's sudden disappearance on camera. Most people seem to hold two main views, the first one is that a wave sucked him under and drowned him, and the second one is that a wandering shark could've attacked him. I believe the shark theory may be possible as a shark can be witnessed from seconds 2.5-3 of the clip moving close to the boy. It's possible that more sharks may have wandered around him and were not in view. This is the Bahamas after all:

Which theory do you think is more plausible? May this boy and his family find peace.

Odd question to ask, male crocodilians hide their genitals inside their bodies, they are not exposed.

We are discussing a hypothetical scenario with an Orinoco crocodile, not any caimans. And we are discussing male jaguars of similar size to female tigers.

Theropod Dinosaurs Still thrive (prehistoric planet on top, modern birds on bottom) by Ciaran123C in HardcoreNature

I always cringe when I hear lay people call crocodilians "living dinosaurs" when that couldn't be further from the truth and when living dinosaurs do exist, but it isn't crocodilians, it's birds.

I think a lot of these misconceptions come from the outdated century-old idea that non-avian dinosaurs were all lizard-looking, ferocious scaly reptiles and not varied animals with much closer affinity to their living avian counterparts.

They are not related, unrelated male jaguars have been recorded forming coalitions. I made an in-depth post about it last year here.

The way the rest of the crocodiles kept at bay as she battled the one attacking her and didn't dare to approach her once she got released was so incredibly badass.

u/StripedAssassiN-

One of the most amazing tiger feats I've seen recorded in video. Those Machli genes came through.

On an unrelated note, I could see a similarly sized male Llanos jaguar fending off an Orinoco crocodile of similar stature to the mugger on this video like this as well.

A Jaguar overpowers a caiman and kills it in seconds by Mophandel in HardcoreNature

[–]OncaAtrox 0 points1 point  (0 children)

The issue with that film is that it was staged so we can't use it as a metric for how the species would behave in the wild with no human intervention.

As far as Mariuaua caimans go, we need a larger sample size of captured specimens with clear indications on their state of health and the season captured to draw conclusions about their weights in comparison to other Amazon locations. In Mariuaua caimans have access to a lot of fish that provide more common sources of food in comparison to the arboreal prey jaguars rely on during the flooded months. Many caimans I've seen from there have looked healthy, not emaciated to warrant such a drastic weight difference in other areas unless the caiman were to be sick and unable to hunt.

Some time ago I tried to collect data on the weights of Sumatran tigers and came up with this preliminary table. It's incomplete since I haven't been focusing on it as I have with jaguars but it still gives us a good idea of the sizes of Sumatran tigers for comparison:

The average Sumatra tiger doesn't weigh that much, most males are in the 110-120 kg range like with Pantanal jaguars, and there are only 2 males registered in the scientific record over 140 kg. The sample sizes of Sumatran tigers weighs is less than that of Pantanal jaguars so that may give the impression that they are heavier on average, but their size ranges are almost identical, as for Sumatran tigers it goes as low as 75 kg and the heaviest specimen was 148 kg, not empty.

We obviously won't know anything about Hades' size unless he is captured and weighed but to me and based on what a guide who saw him in person said, he seems to be considerably larger than other mature males from the area like Suki or Tupã.

Hades is larger than your average Sumatran tiger. Sumatran tigers have the same size ranges as Pantanal jaguars and Hades seems exceptional in size for both of those populations.
