Peacocks may soon be termed vermin in Goa, India. State officials proposed reclassifying the majestic birds after concerns were raised about the agricultural damage they cause. Listing them as a "nuisance animal" will make it easier for them to be hunted or culled.
Jumping spiders learn to distinguish a color -- red, in this case -- in order to suss out whether their prey is toxic or actually a really toothsome bit that nonetheless contains the color red, which is often associated with toxic creatures. This means the spiders can live longer and continue to manage agricultural pests, such as caterpillars, beetles and flies.
