Amazing Blue Bugs, Insects, Frogs, Fish, and Butterflies
If you were to ask a group (just about any group) of people to name their favorite color, more than any other color, they would reply "blue." But, of course, some might change their minds after seeing some of the spiders in this article. The color blue is also considered the most beautiful for the eyes. Blue eyes, blue skies, blue oceans, bluebirds, and blue flowers; we love them all.
But blue pigments are rare in nature, and Mother Nature has always favored green, brown, and other more subdued colors. So with this article, we have set out to showcase some creatures that even Mother Nature would say have the "wow" factor!
Blue Spiders Are a Mystery to Scientists
After reading several scientific journals and reports, it's safe to say that scientists still haven't presented a definitive reason as to why some spiders are blue. However, according to a study at www.sciencemag.org, the glowing blue—rarely found in animal pigments—is structural.
But, a recent study by www.thesun.co.uk suggested that it may have something to do with their evolution pattern.
Blue Poison Dart Frogs
Poison dart frogs (of any color) are considered one of Earth's most poisonous species, each with enough poison to kill thousands of mice. In addition, the color serves as a warning for potential predators to stay away. Scientists usually agree that these frogs get toxicity from the insects they slurp up with their long, sticky tongues. Some insects they like to dine on include small beetles, ants, fruit flies, termites, and crickets. Poison dart frogs can be found in the rainforests of Central and South America.
