How many blue animals can you think of? Probably just a handful, right? The blue jay and blue whale might come to mind, but did you know that there are many more fascinating blue creatures out there? From butterflies and frogs to birds and snakes, the world of blue animals is truly mesmerizing. But have you ever wondered why blue is such a rare color in the animal kingdom? Let’s dive into the enchanting world of blue animals and uncover the secrets behind their captivating hues.
Why Blue Is Actually Rare Among Animals
Unlike pigments like red, brown, orange, and yellow, blue doesn’t come from what animals eat. You may have heard that a salmon’s pink color comes from the pink shellfish it eats, or that a goldfinch’s yellow color is a result of feasting on yellow flowers. But blues are different. In fact, that stunning blue color you see isn’t a pigment at all.
The Reason behind the Blue Color of Blue Animals
So, how do animals get that beautiful blue hue? The answer lies in the structure of their bodies. Many animals have molecules that reflect light in a way that creates a blue color. Take the blue morpho butterfly, for example. Its wings have ridged scales that bend sunlight just right, making its vivid blue color easily visible to our eyes. Even a slight change in the shape of these scales can cause the blue to vanish.
Similarly, a blue bird like the blue jay has feathers containing microscopic beads arranged to scatter all colors of light except blue. This gives them their striking blue appearance. Blue on any animal, including blue eyes in humans, is a result of light reflections. However, there is one exception to this rule – the obrina olivewing butterfly, the only creature on Earth capable of producing blue pigment.
Blue Animals in Nature
Let’s take a closer look at some of the most captivating blue animals in nature.
Blue Jay
The blue jay, with its light blue plumage, black details, and white abdomen, is a native North American bird known for its unmistakable crest of feathers on its head. Blue jays have varied diets, including branches, plants, leaves, worms, insects, and even human refuse. They can build nests in almost any tree species and lay up to five eggs.
Blue Morpho Butterfly
Found in the forests of Central and South America, the blue morpho butterfly is one of the most beautiful blue animals in the world. Its large size and vibrant blue wings, spanning up to 20 cm, make it a sight to behold. While they can fly, these butterflies spend most of their time on the forest floor or among bushes, feeding on caterpillars, plants, and nectar.
Tanzania Electric Blue Gecko
The Williams’ dwarf gecko, also known as the Tanzania electric blue gecko, is a small reptile that measures only 10 cm in length. Males boast a bright blue color, while females are green or brown. These geckos are native to Tanzania and are found exclusively in the Kimboza forest, making them highly sought after in the pet trade.
Blue Iguana
The blue iguana, originating from Grand Cayman Island, is a fascinating blue herbivorous animal. These iguanas can be found in forests, gardens, roads, and even towns. They are excellent climbers and feed on fruit, seeds, flowers, and plants. With their striking blue hue, especially during mating season, blue iguanas are a remarkable sight.
Blue Coral Snake
Blue coral snakes are renowned for their stunning blue-black scales, contrasting with deep red heads and tails. These venomous snakes call the forests of Indonesia, Malaysia, Singapore, and Thailand their home. Feeding exclusively on other snakes, blue coral snakes are both beautiful and dangerous.
