Climbing catfish filmed scaling waterfalls
- neom 1y agoSeems they've figured out how to wiggle themselves forward using their tails, then land in a way that creates a suction between their belly and the rocks. Clever. https://www.researchgate.net/publication/394405635_Bumblebee_on_the_rocks_Massive_aggregation_migratory_and_climbing_behaviour_of_a_small_Neotropical_catfish https://www.researchgate.net/publication/394405635_Bumblebee...

- RajT88 1y agoI think I've seen similar videos of sculpins doing this - who have a suctiony fused set of bottom fins. If sculpins do it, probably some kind of Goby also does it (the two families are very similar in many ways). ETA: I have it backwards, it's gobies: https://youtu.be/QYMMf18hZCs https://youtu.be/QYMMf18hZCs Also Cavefish: https://www.theverge.com/2016/3/25/11303774/walking-fish-thailand-cavefish-evolution-study-njit https://www.theverge.com/2016/3/25/11303774/walking-fish-tha... And yes - as people point out, sea lampreys can do this with their sucky mouths. With with the variety of small fish with sucky mouths, probably there's even more who have learned this trick. Nature is amazing.

- ainiriand 1y agoCatfish is disgusting to eat, at least the ones we have here in Spain, which are sometimes past 50kg.
- cobbzilla 1y agoIn some places hand-fishing for catfish is a time-honored tradition! [1] [2] Soundtrack by The Flaming Lips. Very entertaining. But I don’t think watching would make anyone want to try catfish!

- MisterTea 1y agoEven The catfish we get in the states isn't great. By itself it's not a good tasting fish but it's not inedible. I was given a simple recipe which is to bread chunks of catfish in a 50/50 mix of flour and corn meal seasoned with Lawry's seasoned salt and fry them in light oil. Comes out pretty tasty and even better with lemon and tartar sauce.
- HelloMcFly 1y agoFarm-raised catfish (usually caught in lakes/ponds where it has been stocked) in the US is delicious to many, especially in the South and southern Midwest. Wild catfish can be good too but probably won't be if coming from particularly muddy waters.
- danans 1y agoSomeone once explained to me that the "high end" farmed catfish you get in the US doesn't taste muddy because they feed them from the top of the water rather than having scavenge the bottom of the pond. I've definitely had some good catfish in the US. Sourcing matters, and also probably how you prepare it. Breaded and deep fried is of course tasty, if not healthy. Southeast Asian cuisines are generally very good at preparing catfish - they have a native variety called Basa which is very mild.

- SideburnsOfDoom 1y agoA whole lot of "climbing catfish" were filmed in the act of scaling a waterfall.
- pvaldes 1y ago1) There are species of small "catfishes" (on Asia or Australia if I remember correctly) known to climb waterfalls in rainforests. We are talking about > 100m long fully vertical waterfalls. 2) In fact, they aren't catfishes. Belong to a big family of mainly marine fishes called gobies. Totally different orders. Should be named climbing gobies. 3) They do it for the same reason as Salmons do: to reproduce in freshwater. 4) But unlike salmons they don't swim or jump. They climb the slippery rock wall like a freestyle climber, using the suction cups in their belly that gobies have (pelvic fins transformed), and their other fins and tail to propel 5) Somebody filmed those fishes climbing.
- SideburnsOfDoom 1y agoThe article says "Rochedo, Brazil" so South American rainforests, in this case. These species are "restricted to fresh water in South America" source: https://en.wikipedia.org/wiki/Pseudopimelodidae#Distribution https://en.wikipedia.org/wiki/Pseudopimelodidae#Distribution
- pvaldes 1y agoHum, yep. You are right, Pseudopimelodidae are catfishes. I was thinking in the Hawaiian climbing goby.
- SideburnsOfDoom 1y agoThe original title is plural: "Thousands of climbing catfish filmed scaling waterfalls" The word "catfish" can be singular or plural. I read it as "A catfish was filmed...". But there sure are a lot of those little fish.
- bell-cot 1y ago> ...researchers also found that the [wet-rock-climbing] bumblebee catfish isn’t alone. Three other fish species were also scaling the waterfalls alongside the bumblebee catfish, and none of the four had ever been documented climbing before. Being fish, this sounds like convergent evolution. (Vs. learned behaviors.)
- neom 1y agoThey seem to all be fish that live in fairly fast flowing waters, my guess was they are able to use rocks+suction system to hold in place for stuff, they probably don't even really have a concept they are climbing a wall, it could just feel like a particularly intense rapid?
- bell-cot 1y agoI'd figure it's slightly more complex than that (see details in article) - but I bet you're right about both the evolutionary basis for the behavior pattern, and for having bodies well-adapted to doing it.
- SideburnsOfDoom 1y agoI would say that these are not sharply defined categories, there is more a like a smooth continuum from "fast-flowing stream" to "rapids" to "small waterfall" etc. And this is a good environment in which evolution could progressively improve rock-holding and climbing ability.

- Fluorescence 1y agoI am unreasonably upset by the tiktok-goofy-jazz music they chose. For science.org I want something a bit more nature-documentary e.g. a thoughtful classical/ambient soundscape with David Attenborough gentle tones "And here we see...". If seeking to amuse me then go for it e.g. Ride of Valkeries/Rohirrim.
- ofalkaed 1y agoI found the music a great fit and I would not have enjoyed it as much without. I Would have closed the window if it had been Ride of the Valkyries which is far more generic and overplayed for me than anything tiktok, but I have never used tiktok.
- bevr1337 1y agoI'm a wet blanket, but I despise documentaries that lie about the sound of their recording. I was pretty far into adulthood before I realized most nature docs have fake audio. The backing track of this video helps me know there is no useful audio for this video - no Foley or ambient mic. It's not quite as narrative as Ride of the Valkyries, granted ;)
- dudefeliciano 1y agothis dude made an aquarium with an artificial mini waterfall for the fish to climb https://www.youtube.com/watch?v=qp0SIJNtIKM https://www.youtube.com/watch?v=qp0SIJNtIKM
- elfleco 1y agothis is the most relaxing vid I've seen in a while.
- foobarbecue 1y ago"the catfish adhered to the wet rock by creating a pressurized air bubble under their belly." Presumably they mean negatively pressurized?

- mittsquinter 1y agoIs this like when I laid on my back as a kid by the pool and made fart sounds?

- mzs 1y agonow do eels >At this stage they stop eating, which is probably a good thing as their anus shrinks to prevent water loss. https://www.abc.net.au/news/science/2022-01-09/eels-australia-most-hardcore-animal/100572614 https://www.abc.net.au/news/science/2022-01-09/eels-australi...
