    You should really look up the forest fire burn acreage from the 1920s, 1930s, and 1940s before you say "as forest fires become more intense and widespread due to climate change."

      @Just Julie 111 Hello to you, it's a beautiful sunny day here. Lightning caused fires are no more common now than they were 600 years ago but where I live there has already been three human caused fires! These idiots are going to be the reason that things get shut down. In recent years all backroad access have been closed and even roads to the lakes for fishing are being shut down.

    The fires aren't intense because of climate change its because they won't let the fires burn what happens is that dead plant matter like logs and leaves builds up on the forest floor normally a fire would start and the dead plant matter is burned off and enrich the soil not being strong enough to burn living trees but when you stop the cycle by pouring water on it the dead leaves and logs build up and up and up until you have so much fuel the fires doesn't naturally burn itself out so we have catastrophic fires that burn everything to the ground we caused intense fires by putting the out not by "climate change" you would think a entire channel dedicated to animals and science would recognize that

      Okay, well, there are a lot of factors that play but you can't deny that climate change isn't one of them because that simply isn't true. I'll admit, it's not the only thing that plays apart, but it is definitely something that can greatly affect these things

    i'm confused, how do the beetles get a 12km range? they still need line of sight do the ynot as IR radiation get's absorbed by pretty much anything in the way, now considering beetles have a tendency to be on the ground with lots and lots of foiliage around how can they possibly get a 12km range?

    1. Tom Murphy

      That's their maximum viewing distance, based on experiments. Doesn't matter if something is in the way. For example, you can see farther than 6 inches, right? If you stand facing a brick wall with your nose against it, you can still see more than 6 inches, there's just a wall there. It would be impractical to list the varying ranges, too many variables

    Although I'm not certain it hasn't already been mentioned, or whether you have an episode in the works, but what is up with all this talk in the news about humans sharing a genome that allows for poison glands? If you do an episode on this, please break down to the layman about genomes and how they make up DNA. Admittedly, I am no biological chemist, but it seems logical to me that if there are so many millions of genomes in each critter of every kind, surely there's going to be SOME overlapping there, right?

    How about animals that can detect earthquakes before they occur?, Even though it's off subject I was wondering if those animals had sense organs that allowed them to " see " when an earthquake is about to occur.

I used to be like you but as I’ve come across them more & more it’s helped me get used to them and even actually appreciate them. The green grass ones are actually kind of cute, my daughter and I saw one crossing the street sticking his little tongue out and then just went on his way. There’s some really good yt videos showing how the cottonmouths aren’t as aggressive as everyone says. One guy had to stick his boot in his mouth repeatedly before it finally tried to strike at him and this was after screaming and acting stupid around it while it just sat there. They really are more scared of us than we are of them as hard as that is to believe lol. I also know from past experience that people can say whatever they want but it’s still scary as hell when you come across them. They are very creepy looking creatures.

Went to a camp thing and the campground was known to have a lot of snakes and i was constantly on the verge of tears with anxiety. My friend had no fear of snakes and carried one out of the campground, probably more than once. I saw one the size of a pencil when i got enough courage to go to the camp ground creek with the others and i was DONE! that was long, sorry!

    This is why halogen bulbs are the best heat source you can buy for pet reptiles- they most closely replicate the infrared waves that the sun emits in the wild. Specifically, they emit far more IR-A radiation. Heat mats, radiant heat panels, and ceramic heat emitters all emit IR-C radiation, which doesnt penetrate as deeply into the skin as IR-A, so the reptile will spend more time basking in an attempt to bring its internal body temperature up instead of climbing, digging, exploring, or other behaviors that it would exhibit in the wild, simply because it is too cold.

    Infrared sensing will always be lower resolution. It is the simple feature of wavelength. The longer the wavelength, the bigger the thing it needs to bounce off to see, making each "pixel" fundamentally bigger.

      Lower end Infrared sensors are currently worse than would be implied by their aperture size and target wavelength mainly because they can only use a fraction of the photons that hit them, and can only distinguish differences created by many photons. We have more expensive infrared sensors equivalent in efficiency to black and white visual spectrum cameras, and thus likely much better than even a pit viper's pit, but they require more expensive materials, lesser used manufacturing methods, and cryogenic cooling of the image sensor.

      @Incanus Olórin with an appropriately sized sensor, yes. Considering that we do not have sensors that capture at the upper limit of visible yet, it will be a while before that feature comes into play. That being said, x-ray crystallography does rely on that feature for its functioning. The major problem with high-energy imaging systems is that they are often necessarily destructive. Like, technically gamma radiation has the highest resolution, and should be able to reflect off intermolecular structures, but gamma is so high power that before you could get any details, the subject would be destroyed. Electron microscopy is the best workaround for that issue when it comes to extended objects, but it is still inherently destructive, due to the need to apply a gold monolayer to the subject. Optics and microscopy are fascinating subjects.

    I'm amazed that the pseudo infared images people always use to try to show how pit vipers sense their prey is actually not inaccurate and that they CAN see an image in heat, not just feel a hot spot in a particular direction!

      @Nathan Buth-Chavez The pit organs essentially work like pinhole cameras for the infrared, meaning that by knowing the diameter of the hole and the distance from the hole to the sensor membrane, thermal sensor cell density in the membrane, the resolution can be calculated reasonably well. It's not a high resolution image, but will, under the right conditions give the snake accurate size and distance information about warm blooded organisms.

      To be fair, depending on your exact location and the intensity of the fire, you can literally _see_ a wildfire from quite a distance. They are _very_ visible.

      Good question. Bombardier beetles have developed a way to burn predators as a defense mechanism using chemical fires, so it's clearly something beetles have done before. I'd hazard a guess, though, and say that this could potentially be dangerous for whole ecosystems - and I'm saying that even after acknowledging that fire is actually good for some ecosystems.

      @Cave Boomers Rantings I'm not sure you do understand. You keep mentioning thermal heat when the TrpV1 receptors respond to both thermal heat and capsaicin which is what makes chili peppers spicy. Kyle even provided the exact quote in the video where this is explained and somehow you're still stuck on temperature.
