@TheNailCutter they found the problem to be a vitamin B1 deficiency due to eating this one type of fish that destroys vitamin B1 if they are eaten in large quantities and thanks to human polluting the river most of the other fish died off so the alligators couldn't resupply vitamin B1
The cause is the overpopulation of the swamp with a fish called "gizzard shad", this became the primary food for the alligators, this fish contains an enzyme that is called "Thiaminase" this enzyme destroys thiamine Or also know as B1, lack of B1 drivers to neurons death due to insufficient nutrition. So over time the brain activity stops till it gets to the zombie state.
Why do all of NG's videos have to leave us on a cliffhanger? I get that they want us to watch the program, but it aired 3.5 flippin years ago- can you just tack on the endings please??
I was hoping they would explain why they are zombie alligators! Weres the rest of the documentary!? Did they find out what was causing it!? U cant just leave it on a cliffhanger like that!!
@deathwings11 I just watched this on NatGeo Wild. This condition is caused by a lack of thiamine in their diet. The lake is so polluted that the only fish that can thrive in the lake are Shad. These fish produce enzymes that when eaten by the alligators it breaks down the thiamine in the alligators system. Without thiamine, the alligators become lethargic and suffer from a lack of oxygen to their bloodstream. Recently the lake has been harvested of Shad and now the gators are recovering.
@BudzMcgr33n Ah excellent, thanks very very much for takin the time to explain that too us! :) That was very strange that it was happening, especially to those living dinosaurs that hav made it this far. It wud be a shame if they died out. Although maybe thats presumptious of me as they probly wud of adapted, lol.
As vicious and ugly as alligators are im glad they found out what happened to them, the world wouldnt be the same without them. Sharks also carry the same stigma as alligators....killing machines. I wonder what they would think about us humans? We are probably the worst things that ever walked the face of the earth. : (

@muzikkid33 hes doing it coz hes trying to find wats wrong and wanted to stop it so no more animals die and anyway the animal is already dead, fucking hippy.
@MrTikimon Dude why do you have to get all offended by what I say it was my opinion and I just think that is nasty i'm not saying that it's wrong to do that i'm just saying that it's DISGUSTING it is my opinion and by the way I was kind of joking when I typed that.
They were eating some sort of fish that made them have a Vitamin B deficiency, causing their brain cells to die off. Fish were removed, problem was solved.
Found this: The conclusion: Pesticide runoff had killed off the biodiversity of the lake, creating a lake that overly nutrient rich. This rich environment enabled a fish called the Gizzard Shad to overpopulate the lake. The Shad, which became the zombie gators primary food source, produce a chemical which inhibits the absorption of thiamine. And thus, the zombie gators.
being a doctor i speculate that it might have to do with drop in temprature as the cant bask in sun or get as much sunlight or the temp of water is cooler,even a couple of degress is a substantial change for reptile My secound guess is neurogical problem,or might have to do with less pray in lakes!lol

*Drowning
*Lie down as if they are dead.
*Hard time riding themself in the water
*They listed to one side or the other
*Look like they were drugged almost
