Animal Metallicism: 10 Amazing Golden Creatures


Got the gold bug? Golden animals are both beautiful and rare, much like the precious metal itself. These colorful insects, arachnids, vertebrates – and even one very special lady – are linked by a common bond: the warm, golden glow that gives them the look of exquisite, living treasures.

Golden Beetles


Certain types of beetles can appear so golden it’s hard to believe they haven’t somehow incorporated 24-carat gold into their gleaming shells! They haven’t – if they did, human treasure hunters would have long since driven them to extinction. Among the most golden of these “gold bugs” are the Golden Scarab Beetle and the Golden Tortoise Beetle.

These insects get their golden appearance using some pretty sophisticated science. The Golden Tortoise Beetle can adjust the moisture content between two layers of its wing covers, resulting in varying levels or golden iridescence as seen by the human eye.
The Golden Scarab Beetle (Chrysina resplendens) goes even further: its chitinous cuticle reflects circularly polarized light which is “left-handed”. Sounds complicated; looks brilliant!

Golden Jumping Spiders

Jumping spiders are hunters and ambush predators rather than web-weavers so one would think having a gleaming, metallic exoskeleton would not be in their best interest. Possibly these spiders’ golden appearance is something only human eyes – and not those of its prey – can appreciate.
Jumping spiders are one of the most intelligent spider species and this 1/4-inch long iridescent gold example is one of the most striking in appearance. The rose petal upon which this jewel-like arachnid has set up his or her hunting grounds makes a pleasing contrast with the shimmering iridescent gold of the spider’s exoskeleton.

Golden Monarch Butterfly Chrysalis

Monarch butterflies are known for their bold orange wings bisected with black veins and contrasting white spots. Their caterpillars, often found grazing on Milkweed plants, are striped with black, white and yellow. It’s only in this majestic creature’s intermediate stage that it chooses to flash its gold: the chrysalis. Oh, uhh, the dude in the chrysalis suit? Gold, pure (comedy) gold.
A Monarch butterfly chrysalis is mainly emerald or jade green in color highlighted by bright metallic gold trim – a horizontal line about 1/3 of the way down and raised golden bumps set apart symmetrically on its lower portion. About 24 hours before the butterfly emerges from the chrysalis, the surface will darken and then turn transparent. Through this process and even after the butterfly has emerged, the golden stripe and spots remain.

Golden Fish

To quote the website copy describing this “truly unbelievable” golden fish, “This is an amazing creation of the Creator. Gold Fish, which was found in the sea in Taiwan was put to display in Taiwan’s Natural Museum.” Okie dokie, I have an open mind and I’m sure you do too… but then: “Scientists have found that some of the parts of this beautiful fish are of 24 carat pure gold.”That noise you heard? That was my mind snapping shut.
Seems this particular goldfish, er, gold fish is an animatronic device that may have a creator; just not THE Creator. One can be sure, however, that Koi breeders are actively engaged in producing a truly believable golden ornamental carp. Such a fish might not have 24-carat gold parts but eager buyers would likely pay as if they were.

Golden Poison-Dart Frog

There are several different species of Golden Poison Frogs including Phyllobates terribilis, said to be the world’s most poisonous vertebrate. Just how deadly are the alkaloid toxins exuded by these frogs through their skin? Just milligram of the frog’s Batrachotoxin poison is enough to kill approximately 10,000 mice, or 10 to 20 humans, or two African bull elephants – from 1/1,000th of a gram of poison! Another way of stating its toxicity is roughly 15,000 humans killed per gram. “Look but don’t touch” was never so appropriate.
Golden Poison Frogs are not metallic gold in hue; in fact they can be pale green, various shades of yellow or even bright orange. Where you WILL see metallic gold on frogs (or toads) is in their eyes – the iris’ of many types of common frogs and toads displays a rich, brassy golden tone that contrasts with a midnight black background. Quite beautiful… some might even say, hypnotic.

Gold Tegu Lizard

The Gold Tegu lizard is a large South American lizard that exploits a similar ecologic niche to that of monitor lizards on other continents. The Gold Tegu’s glossy skin and ornate gold over black striping combine to make it visually very appealing.
Gold Tegu lizards are popular pets though their feisty nature and hard-to-tame aggressiveness makes them a real handful. Speaking of which, a Gold Tegu can grow rather large – up to 44″ long from tip of the nose to the end of their tails – and unlike other Tegu species they are mainly carnivorous.

Golden Snakes

Several different species of snakes have been graced with the prefix “golden”, including the Golden Tree Snake and the Golden Cat Snake. Most gold-toned snakes live in desert habitats where their coloration helps them blend in with the sandy ground and dry vegetation of arid climes.
Now here’s one “rattler” that one wouldn’t mind having coiled close by – it’s one way to un-constrict your finances, at least. I’d say the gilded serpent above was both real and available but then… I’d be speaking with a forked tongue.

Golden Marmoset

The Golden Marmoset, or Golden Lion Tamarin (Leontopithecus rosalia), is one of the smallest monkeys and also one of the most endangered. It’s estimated only about 1,000 of these primates survive in forested areas of Brazil’s Atlantic coast while another 490 are currently kept in captivity or on protected reserves. It’s estimated that 98 percent of the Golden Marmoset’s original lush rainforest habitat has been destroyed through logging and/or agriculture.
The thick, golden fur covering the Golden Marmoset makes it appear larger and heaver than it really is. In actual fact, these New World monkeys only grow up to 13.2 inches (335mm) long and can weight up to 25 ounces (about 700 grams) when fully grown.

Golden Weaver Bird

The African Golden Weaver (Ploceus subaureus) can be found in eastern and southern Africa roughly from Kenya down to South Africa. These birds can form flocks of many thousands and their teardrop-shaped nests may hang from leaf-stripped savannah trees by the dozens.
Golden Weaver Birds are not considered to be threatened and indeed, one of their relatives (the Red-billed Quelea) is considered to be the world’s most abundant bird with a population of approximately 1.5 billion. All Weavers are seed-eaters, and flocks sometimes cause African farmers problems when they settle en masse to gorge themselves on mature seed crops.

Golden Bond Girl

Our last (but not least) golden creature is of the species Homo Sapien, commonly known as Shirley Eaton, Bond Girl. Eaton played the role of Jill Masterson in the 1964 James Bond film Goldfinger. Her claim to fame was her on-screen demise, considered by movie pundits to be one of the top ten film deaths. The crucial scene features Eaton sprawled nude on a bed, her body completely covered in gold. Betty White’s cool and all, but Shirley Eaton is one hot Golden Girl! Here’s a video clip of the notorious (for 1964) scene:
The Jill Masterson character supposedly died from “skin suffocation”, a questionable proposition that incidentally was investigated in a memorable episode of the Mythbusters television series. Shirley Eaton was said to suffer no ill effects from her movie makeup though the film’s producers kept a doctor on hand while filming “just in case”. As for Mythbuster’s Adam Savage, his head to toe gold painting also left him none the worse for wear though his pride was somewhat dented.

All that glitters isn’t always gold and what appears to be gold may or may not glitter – then again, animals are animate objects and their golden garb has value much more than that of the metal that has enticed, entranced and blinded humans from time immemorial.

Ardent In Argent: 10 Amazing Silver Animals


From metallic mirrored beetles to stately senior simians, the serene beauty of silver animals reflects their rank as some of nature’s most exquisite creatures. Though gold may be more flashy, silver animals are no second bananas and take a back seat to nobody. Best of all, their ardent argent adornment never tarnishes no matter what the weather.

Silverfish

Silverfish (Lespisma sacchrina) are wingless insects that can grow up to 3/4″ (about 2cm) in length. They’re soft-bodied creatures that move with a sinuous, fish-like motion – the origin of their most common colloquial name. Silverfish appear silvery due to their many ridged overlapping scales that reflect light. The scales are easily dislodged which makes it seem like these common household pests are “dusted” with silver.

Silver Beetle

Glistening metallic beetles living in Costa Rica’s rainforests have tantalized and delighted those who’ve spied them over the centuries. Indeed, these beetles (Chrysina limbata) and their golden relatives (Chrysina aurigans) are the most metallic-looking of any animal. Their secret lies in the chitinous wing covers that cover most of their upper bodies. Up to 70 thin, semi-transparent layers of chitin reflect and amplify light without the need for any actual metal.

Silver Fly

The most familiar metallic-bodied flies are so-called Blow-Flies and Bottle Flies of the family Calliphoridae, the latter often displaying reflective blue or green bodies. Some species of flies emerge from their pupal stage unpigmented, however, and their shiny exoskeletons therefore appear to have a silvery sheen. Macro photographs of these newly emergent flies can remind viewers of futuristic cyborg robots rather than ordinary insects.

Silver Spider

The ominously large silver spider at the top of the composite image above belongs to the genus Cyphonisia and is known colloquially as the Silver Trapdoor Spider – definitely something one doesn’t want to drop in on! The smaller and more silvery spiders above are known as Dewdrop Spiders. These small, jewel-like spiders of the genus Argyrodes don’t construct webs of their own, preferring to lurk in and around the webs of larger garden spiders where their shining bodies remind onlookers of droplets of morning dew.

Silver Fish


One of the wonders of the ocean is a massive school made up of hundreds – even thousands – of sleek, silvery fish. Congregating together as a representation of the theory of “safety in numbers”, schools of fish protect their species as a whole while providing predators with easy pickings at the same time. As for their silver scales, a huge number of fish species adopt this method of distracting camouflage that has the added benefit of making their bodies smoother, allowing for faster movement.

Silver Frog

The amazing silver frogs captured photographically above by James Gunter live in small pools situated within blisteringly hot and dry desert environments. It may be that these frogs have evolved semi-transparent reflective skin in order to deflect the sun’s more damaging visible and ultraviolet rays. Frogs and other amphibians respire partially through their skin and dehydration is always an issue – in the desert, keeping moist would be paramount.

Silver Lizard

Leapin’ lizards! Well, even stationary lizards can be silver, at least certain parts thereof. And in certain parts of Australia, several species of Skinks exhibit at least some degree of silvery scaliness. As is the usual case with “metallic animals”, no actual metal is required to effect a reflective appearance. Rather, these creatures have evolved metallic shininess as a survival strategy we just happen to think looks pretty.

Silver Snake

Snakes and lizards are both reptiles and both feature oft-colorful scales adorning their bodies. Some species of snakes have scales so shiny they appear to be reflective under the right lighting conditions. Such silvery snakes aren’t as exotic as one might think: the relatively common Rat Snakes above gleam with a soft silver glow that belies their humble origins.

Silver Fox

The Silver Fox is a melanistic variation of the more common Red Fox – approximately 8 percent of wild foxes in Canada display glossy, silvery fur that on close inspection is actually made up of dark brown, gray and white hairs. Silver Foxes are the subjects of an ongoing experiment in fox domestication instigated by Russian scientist Dmitry Belyaev in 1959. Belyaev bred Silver Foxes for tameness over many generations and observed the foxes gradually becoming more dog-like in both their behavior and their appearance. One result of the experiment was that the selectively bred Silver Foxes lost their “silver” fur in favor of multicolored coats more commonly seen on domesticated dogs, cats, cows and pigs.

Silverback Gorilla

Going gray… not just for people anymore! It’s not known why aged male gorillas go gray on their backs and hindquarters; it’s also not clear if other gorillas note the distinctive look of such “silverbacks” and adjust their behavior accordingly. Suffice to say that in gorilla society, as it were, being a silverback means you’ve made it to the peak of power and influence. Reaching a state of silveriness is common to both mountain Gorillas and their Lowland cousins. Unlike humans, curiously, only male gorillas go gray in the manner.

Humans may be animals but there’s nothing more exotic than changing one’s appearance with silver or other metallic body paint and makeup. That’s because unlike our animal relatives, humans haven’t evolved body parts that are sufficiently reflective to be considered silvery. Mirror, mirror, on my skin, who’s the fairest, me or my kin?

Animals in Africa, from A to Z



Africa is home of some of the most well known, loved, feared animals in the world. They are so many and so wonderful we’ve made an A to Z list of African animals (only missing the Q unfortunately).

A

Aardvark

This medium seized nocturnal mammal native to Africa only eats ants, termites and one type of cucumber, called aardvark cucumber and it is believed by African magicians to have magical powers.

B

Baboon

These monkeys are furry and noisy but very caring to their young. They are omnivore foragers, but are also known to eat sheep, goats and small antelopes. In Egyptian folklore, Baboons were considered sacred animals.

C

Cheetah

This large feline is the fastest animal on land running with a speed up to 120 km/hours in short 500 meter bursts. It can accelerate from 0 to 100 km/hours in 3 seconds. They have non-retractable claws so they can’t climb tall trees.

D

Desert Warthog

While some say this is not the prettiest pig relative out there, we just can’t ignore his resemblance to Pumba (the Lion King character) and think it’s quite a character with its huge tusks and care for hie non-stop following young.

E

Elephant

With elephants being the largest creatures on land at the moment it’s no wonder their babies weight 100 kilograms at birth. But did you know the gestation period lasts for 22 months?

F

Fennec Fox

With a total body length between 24 and 40 cm, this big eared guy is the smallest fox there is. His ears help him detect insects and rodents hiding underground.

G

Giraffe

With it long neck the giraffe can reach the talles and tastiest leaves in the savanna and also engage in “neckings”, a type of male combat in which the neck is used as a weapon. Invulnerable to predators as an adult, calf giraffes are hunted by lions, leopard and hyenas.

H

Hippo

Hippos are large, mostly herbivorous,  semi-aquatic mammals. Despite their pig like appearance their closest relatives are whales, from which they diverged some 55 millions of years ago.

I

Impala

One of the most abundant antelopes in Africa, the impalas, can grow up to 95 cm tall.  Only the males have horns, which they use in territorial battles.

J

Jackal

These far away relatives of the wolves are crepuscular, being most active at dawn and dusk. They are scavengers and hunters of small animals. In oriental mythology jackals are clever sorcerers, while in Egyptian religion it is the God of afterlife.

K

Klipspringer

These half a meter tall antelopes can fit all fours hooves on a piece of cliff the size of a coin and never have to drink water, since the succulent plant they forage on provide them with sufficient water.

L

Lion

The King of the Jungle, the second largest feline after the Tiger, the Lion is today considered a vulnerable specie, with its population decline of thirty to fifty percent in the last 20 years.

M

Mongoose

Close relatives of Meerkats, mongooses are very attentive little creatures, also using a sentinel to keep eye on eventual predators, such as birds of prey. They eat insects, small rodents and birds.

N

Nyala

This medium sized antelope prefers a deep forest to any plain there is in Africa. While the females are warm brown and horn-less as the nyala pictured below, the males are dark skinned with long spiraled horns and a woolly fringe on their belly.

O

Otter

Otters are semi-aquatic mammals which feed on fish, birds and small mammals. They are also the best swimming teachers out there. Check out this video of a mother otter swimming its pup to swim.

P

Porcupine

Porcupines are rounded, large, slow rodents. Their body is covered with large, pointy spines. Porcupines are salt lickers and will lick and eat anything that is covered in salt, from household items such as tables or clothes to vehicle tires coated in road salt.

Z

Zebra

Relatives of the more common horse, zebras are very unpredictable animals and don’t cope well with stress, reason for which they could never be domesticated. Their famous stripes are different and unique to each individual, just like a human fingerprint.
