1/10/2003: Infrared zoo

The net is so full of stuff that's fun to look at just casually. I had an image all set today, ready to go, uploaded and everything, and then I decided I was weak on information and decided to do a little research on the animal I was posting. And within a few Googles I was at the Infrared Zoo.

This is meant to be an educational thing for the kiddies, from NASA and Caltech, but I found it so interesting that I had to check out a lot of the animals. I'm sure they meant to highlight the differences between the warm-blooded and cold-blooded animals but I found it very interesting to look at some of the warm-blooded and see where they were giving off heat. And sometimes the images wind up a little spooky.

That wolf/bear looks HAPPY!

He is!

Yup. Small cute animals have the ability to render me to goo. :) I had a border collie/collie mix named Sofie. I raised her from a wee pup, and had to put her down a few years ago. She was 15 happy years old.

Her nose was cold, but somewhat above ambient temperature.

I once saw a thermal image of an arctic fox resting on an ice sheet. The entire image was blue (ambient temp) except for the fox's eyes, nose, and mouth. The rest of his body was not radiating *any* heat to the environment. Most impressive.

The link to the zoo isn't working for me :(

it looks like everything below the root page is broken right now.

They moved it! I found the new location and edited the URL in the original post.

This is calling to my memory an article about desert animals. It mentioned a fox that had very large ears to cool down.

The pig has slightly warmer eyes than the rest of it's face. I wonder how much heat humans radiate at their eyes and ears and mouth, as compared to areas just skin [or with hair].

     Wow, you learn something new every day. I was going through them with my ten year old, and found chickens listed under mammals. Well, I'm certainly not as well edumacated as these guys so I guess I just learned something. It's odd though, they certainly seem more like birds than mammals to me...:rolleyes:

The images of reptiles are almost entirely uninteresting. For some unexplicable reason, almost every picture of a cold-blooded reptile is shown with the reptile being held by a warm-blooded human. This, of course, drowns out any thermal variation in most of the pictures, not that the reptiles seem to have much to begin with.

In the picture with the Gecko, it is noticeable that it's eyes are very cold, showing up as black, an interesting contrast with the white hot eyes of the mammals.

Otherwise, feel free to contrast the cold-blooded reptile with the warm-blooded human [hand], time and time again. They only need one picture of a reptile to do that, not six.

I think you might be missing the point, Whit. You do not seem to understand how convoluted these matters can be. The people that set up the Infrared Zoo know that they are birds, and even call them birds in their profile. However, it would appear that chickens are mammalian birds, or mammal-like birds, or part of the obfuscated, government-secret bird classification within mammals.

I probably would have to have a degree in the matter if I wanted to tell you more clearly why Chickens are mammals, however.

Chickens don't fly. Therefore Mammal.

I would guess looking uninteresting to a heat-sensing pit viper is a good thing. It's interesting that this thread showed up when it did. The night before, I was watching a show, "the Human Animal". There were various infrared images of people and thier naughty bits. It was really quite interesting. I suppose I could sum it up by saying things get hot when you get hot.

     Thanks for the clarification on that Torrere, I figured the goverment must be invoved if the chickens are considered mammals now. It does seem to suggest bureaucracy at work.

     Oh yeah, hey Wolf, the only reason chickens don't fly is because humans clip their wings. Trust me, I've been in the back woods of Arkasas where they don't bother to. It's really surreal to see a chicken fly up into a tree to perch on a branch. Odd though, it's only strange because human's intervention is so common...

     Oh well, I like chicken sandwiches...
