Surfers searching for an online zoo with a difference should enjoy this site.
The Infrared Zoo has a collection of photos showing the heat radiated by a range of animals from alligators to worms.
With infrared, it is possible to see the differences between warm and cold-blooded animals.
We can also study how well feathers, fur and blubber insulate animals.
Children especially should enjoy touring the zoo and learning things about the animals they wouldn't from a normal photograph.
The zoo covers birds, mammals, insects and arachnids, reptiles and amphibians.
Mammals are warm-blooded, generating their own heat.
They also try to maintain a constant internal temperature.
In the infrared images on the site, you can see how warm a baboon is compared with her surroundings.
The brightest areas are the eyes, which are not covered by skin or fur.
The bright areas on her body is where the fur is thin, allowing body heat to escape more easily.
In contrast, alligators are cold-blooded so they cannot generate their own heat. Instead, they take on the temperature of their environment.
Even if you don't want to get educated, there are some great infrared photos to bring out the animal in you.
