The largest living carnivorous piranha species is the black piranha (Serrasalmus rhombeus) which maxes out at around 60cm. Also red bellied piranhas only max out at 37 cm. Additionally, if you want to get technical, the largest living piranha species is the mainly herbivorous pacu which can grow to over a meter, which actually makes it similar in length to Megapiranha (M. paranensis), but with a more robust build (if M. paranensis was similar in build to the carnivorous species like the red bellied and black piranhas). You even showed a picture of a fisherman holding a juvenile/subadult pacu in this video.
I thought I saw on some videos that pacu introduced into Timor, New Guinea and Indonesian waterways are now even bigger, and forced to learn how to be omnivore to live in the new world. They were brought there as farm fish back in the 70's and escaped.

Well, there some evidence of a very large tentacled creature that has it's breeding ground off our southeastern coastal area so I wouldn't be surprised to find associated creatures hanging around.
There are many more animals that are tiny today, but in the past, they were giant: Birds, Pigs, Sharks, Rhinos, Komodo Dragons... etc. By the way, nice job! You can do a part two of this!
It shouldn't really come as a surprise. You could say that pretty much any living group today used to be at some point in the history, when the conditions were right, much bigger. Apart from filter feeding whales perhaps, who are at their peak (so far) today.

When you consider that piranhas live with a metric ton of much bigger opportunistic carnivores, you quickly realize that their swarming behavior is defensive, with the same logic as schooling fish in the ocean.
While fishing in the very southernmost portion of Venezuela, we managed to catch a number of Black Piranha, with the largest I caught over 5 lbs in weight and a foot long. We also caught a number of Red Piranha but the largest was at most, about 2.5 lbs and 9 inches long. While the Reds (and Silvers) were caught in back eddies and isolated pools, the Blacks were caught in very fast flowing rivers and we caught them by chance, while fishing for Pyarraha. We used very large (Husky) Rappala lures and a big Black actually snapped one of these in half on me when it struck! It was only the wire that ran the length of the lure's internal body that kept it attached but I suspect that the fish could no doubt have severed it too had it just been bare wire.

@@samuelnobre150 It depends on the situation. In the Amazon Pacu are mainly feeding off fruits & nuts that fall in the water. In captivity, the ones I've worked with become garbage dumpsters, eating literally anything thrown in their tank. I had one rip up standard airline tubing once LOL. Then there are cases in Africa where they've been introduced as a food fish, only to turn into an apex omnivore.
hey dude. a little bit more research will help your future videos. There are multiple species of Piranha today larger then the red belly, including the black piranha, the Rio São Francisco piranha, and the vegan pacu piranha. for the record, the largest living piranha is the Rio.
He mentioned the black piranha briefly, regarding bite force and then talked about it's greater size, I actually re watched that bit cause I thought the same as you at first
I really appreciate the work you put into your videos and for me, it makes me want to learn more and do some weekend researching. Keep up the great work & looking forward to more videos!
Regarding the giant otter omoensis in some parts of Africa, it is said that the water lion is described as a giant otter, something that also happens with the nunda believed to be a dinofelis.
Well done. I appreciate your narration, it is well-paced, not too fast or slow, has emphasis where needed and not a monotone reading. I feel this gives your videos a more personal feel, your conveyance of educational information directed at a listening audience that is given time to process. Really enjoyed the video, and didn't mean to critique, simply wanted to let you know what you're doing right.
I think Purussaurus should've been on this list. Caimans today are not known for being large crocodilians and often are kept as exotic pets due to their modest size. Obviously one couldn't keep Purussaurus as a pet...
If the thought of a giant otter doesn't scare you it should. Otters are smart, vicious enough to fend off jaguars, and sometimes play with their food, which is the true sign of a badass in nature.
I wish some of these, especially the glyptodonts and giant piranhas (only because they belong to characiformes and i want more characiformes species), were still around today
Australia had some interesting megafauna. And being named by Australians they have some fun names, such as *The Demon Duck of Doom* and *Monty Pythonoides* aka the Monty Python. If you want to mess with a 2 metre tall carnivorous kangaroo... good luck to you.
I had to give up on this after a short while of the piranha bit..... a rhombeus type piranha is called a nattereri; (red belly); and then we have a Phractocephalus (naked catfish) used to illustrate the idea of an armoured catfish. Better research please......
4:36 With its size and location in the ecosystem, it would be odd for it to be exclusively carnivorous. It’s body plan would probably function better for grazing since it was low to the ground and armored up, meanwhile if it was a hunter, its size would be a waste of energy since it was the largest land organism at that time.
I got an idea for a video for ya. These three species have very little media coverage but they could be good topics. The Tyto pollens, Bubo osvaldoi, and Ornimegalonyx. I have a very big love for owls and giant owls are just even more interesting to me. Heck, Ornimegalonyx was mistaken for a terror bird upon discovery. Some people apparently have sighted Tyto pollens before and some say it's the inspiration for the legend of the Chickcharney.
If you play the computer game Ark Survival Evolved, or Ark Survival Ascended, you will not only be familiar with many of these creatures, but you will have fought and even tamed some of them
The otters body is designed to hunt in water, could this otter hunt much like crocodiles an ambush predator? He couldn't run very fast on land with short legs.
Bro the pic w the guy holding huge fish is NOT a red piranha - its a Pacu, it's a larger cousin, but they eat nuts only, no sharp teeth instead a nutcracker set of dentition
Arthropleura isnt scary, its the ultimate cool pet! Also early hominids had every op lol, they had to deal with actual massive crocodiles, and then a smelly beast with the personality of a chainsaw cosplaying as one.
Heh, Arthropleura... I'd bet that if it was discovered to actually not be extinct, people would be even more horrified than they would if someone discovered a hidden population of living Tyrannosaurs somewhere. Ah, I should point out that at the time Arthropleura and Meganeura existed, _grass_ had not yet evolved, so your picture of it in a grassy meadow could not have happened.
