By combining images taken through different filters in the visible and infrared, the MESSENGER data allow Mercury to be seen in a variety of high-resolution color views not previously possible. MESSENGER's eyes can see far beyond the color range of the human eye, and the colors seen in the accompanying image are somewhat different from what a human would see.

The copperhead's venom glands, venom ducts, fangs and venom evolved to allow them to kill mice and other prey animals. They bite a prey animal, inject venom, then quickly release the prey. The mouse or other prey dies in minutes and all the snake has to do is follow the odor trail and eat the freshly killed rodent.
