Blue Is the Most Popular Color in the World

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." Of course, after seeing some of the spiders in this article, that reply might change, but that is doubtful. The color blue is also considered the most beautiful when it comes to eyes. Blue eyes, blue skies, blue oceans, blue birds and blue flowers...we love them all.

But, blue pigments are rare in nature and Mother Nature has always had a way of favoring green, brown and other duller colors. With this article, we have set out to showcase some creatures for which she has chosen the most popular color in the world.

Blue Spiders

This amazing blue arachnid is known by many names, including peacock tarantula, Gooty tarantula, metallic tarantula, peacock parachute spider and salepurgu.   They only look irridescent, but  researchers at the University of Akron say they aren't.This is an adult male greenbottle blue (Chromatopelma cyaneopubescens) tarantula, native to Venezuela.This is a blue ornamental sapphire gooty spider - found in the forest of Andhra Pradesh India, and named after the town of Gooty.  These guys are very fast and have a serious bite, so steer clear.

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. According to a study reported at www.sciencemag.org, the glowing blue - a color rarely found in animal pigments - is a structural color.

But, a recent study reported by www.thesun.co.uk suggested that it may have something to do with their evolution pattern.

If you just can't get enough of blue spiders in your life, this poster is available online - thanks, but I'm going to pass.

Blue Cloud Forest Millipede

It's important to remember that just because something is beautiful, there's no need to touch - this beauty's toxic secretions are deadly.  This is the blue cloud forest millipede (Pararhachistes potosinus) and it is the largest millipede on earth.

The Blue Dragonfly

There's no need to be afraid of this beautiful blue dragonfly.  He won't sting or bite, but can fly up to about 30 miles per hour, so if you blink you may miss him.  Check for these guys around water.

Blue Poison Dart Frogs

These frogs (in any color) are considered one of Earth's most toxic, or poisonous, species, each with enough poison to kill thousands of mice. The color is a notification for potential predators to stay away. Scientists pretty much agree that these frogs get their toxicity from the insects they slurp up with their long, sticky tongues. Some of the 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.

This gorgeous butterfly is found in many places across southern England.This male silver-studded blue butterfly (Plebejus argus) has an almost mystical look about it with its glistening, silvery metallic spots. They are commonly found in England and Wales.

The blue crabVelella (Velella velella) is a free-floating hydrozoa that lives on the surface of the ocean.  They aren't poisonous to the touch and they don't sting, but scientists say they carry a neurotoxin, so it's best to avoid them.  This is a blue jellyfish (Cyanea lamarckii) photographed out in open waters.   Young specimens have no color, but they take on color as they mature.
