These creatures feed on the remnants of a world that has long since passed on. They have evolved to be able to extract nutrients from the plentiful bounty of twisted and rusting metal. The beast features a sort of "power shovel" head that can dig through debris and rubble. His meal is further processed inside his mouth where a corrosive and acidic saliva collects and breaks down the material. There is also an inner mouth with nubby metallic teeth which break down the objects further. Once the material is swallowed, it is transported through a series of chambers and stomachs where it is further broken down. This process creates an enormous amount of toxic gases. These are expelled through metallic-like pipes that reside on the back of these creatures. As the beast gets older, it's "pipes" and external shovel-beak tend to grow in size due to a lifetime of ingesting different metals.
Crabbage have specialized sets of mandibles that allow them to quickly whittle down rusting metal into a nourishing slop.
The high level of oxidized iron in its diet (as well as its need to roll in filth) gives the Crabbage a rusty colouration similar to its post-apocalyptic surrounds.
The word ‘anarchy’ comes from the ancient Greek αναρχία in which αν meant ‘without’ and αρχία meant first a military ‘leader’ and then ‘ruler’. Anarchist society is one ‘without rulers’: a classless, non-hierarchical society.

Here's my rather conservative entry. The topic suggested to me that this creature might exist in the near future among the detritus of human civilisation. So I chose to work with a not too distant descendant of an existing animal that could conceivably develop the caustic digestive ability to deal with metals. And nostalgically, the fact that these guys are endangered for the sake of the sexual insecurities of a few overwealthed, underbrained humans really grinds my gears - so it warms my cynical heart to think they may outlast us.

Concept: Hopping Junkroach In the wastelands of post apocalyptic cities, junkroach roams neverending junkyards in a grasshopper fashion looking for the most delicious pieces of rusty metal. These creatures are believed to be a mutated cross of a cockroach, rat or even human as a result of tremendous amounts of radiation. Junkroach is one of the few more complex lifeforms that inhabits these areas and has no virtual enemies or predators that could pose danger to this species. But even in this devastated by war and radiation deserted city mother nature is seeking the balance: the creature is pretty much self destructive as the amount of metal it consumes is slightly more than the amount of metal it's powerful stomach can digest and process. Because of this by the time the creature has reached its adulthood its stomach is filled with metal deposits that make the creature immobile. And so it dies.

the volusians are a highly intelligent race of beings that travel throughout the universe looking for planets that have been destroyed by their inhabitants. they seek them so that they might cleanse them, and allow them to be reborn. once they find these post apocalyptic planets, they release these guys, the volusian cleaner bugs.
once released onto a wasted planet, the bugs search out unnatural, natively created material. and more specifically metals. the volusians have bred these creatures to digest and gain nutrition from what they call, "tainted metal" or rusted metals. the reasoning is that they have found efficient ways of cleaning other waste such as toxic refuse, and radiation. but for some reason have always had difficulty removing formed, and in turn degrading metal material. thus the need for these guys.
the bugs eat the metal by producing a highly acidic bile, which they purge onto the metal they seek to ingest. the bile breaks down the metal on a molecular level turning it into a kind of liquid state. once this happens the bug will use its sucker-like protrusion on the underside of its body to suck up the bile-liquid metal stew. this usually takes them about 50 to 70 generations to purge a planet of its "bad" metal (the bugs life span being about 5 years), or approximately 250-300 years. the volusians don't mind the wait because they are a patient, shamanic species that feel they are saving the universe by returning damaged worlds to their natural state, all done in order to start the process of life over again.
Engineered by ComarcaKolibriBiotech in the wake of rapacious environmental destruction eventually culminating in a number of major resource wars and a precipitous decline in global biodiversity, the VBO was developed to help clean some of the world's worst ecological disaster zones.
This species is capable of efficiently metabolising or sequestering a large number of waste metals, which it integrates into its carapace to lend enormous compressive and tensile strength to its various incisors. The claw on its head acts as a sort of biological tin-snip, allowing it to cut sheet metal, wires and foil into manageable chunks. Scaled for size, its bite is the most powerful known and is capable of shattering nitrided steel. This species can also secrete a rather reactive digestive solution of concentrated hydrogen peroxide and nitric acid, which assists in breaking down tough junk, be it e-waste, military wreckage or unexploded ordnance.
They love depleted uranium and are not recommended as pets. Their bright colouration is due to the sequestration of a number of colourful but toxic heavy metal salts in their pygidial segment. This accumulation eventually results in a sort of mange that is eventually fatal. The colour intensifies over time until they are 'ripe', at which point they may be 'harvested' by recyclers to reclaim their metal content.
ComarcaKolibriBiotech has received mixed appraisals regarding the ethics of engineering this species, especially in light of the fact that they sell a proprietary repellent to keep the creatures away from load-bearing structures and vehicles.
Concept: Scrapworm A wormlike species colloquial known as scrapworm that eats all kind of metal originally living at mountains and deep caves devouring iron ore its now often located scavenging at past battlefields.
We always belived that the rats and roaches would be the only species surviving a nuclear war.
We were wrong.
However there is not many scientists left among us and we do not have access to any research equipment so we simply dont know what species evolved into this. Atleast they arent touching non corroded materials so the shelter is safe. It seems like they are dependant on corrosion to feed, or maybe it's the rust itself they thrive on. We tried to hunt them for food, they are slow and easy to spot but our weapons wont penetrate their thick hides. Useless.
As they devour the rusting metals on waste disposal planets, these creatures work their way trough piles and piles of metal trash. Elements required for chemosynthesis are extracted and accumulate on the body itself if 'food' is abundant. Their home planet of Belphon is nearly depleted, and many populations have been moved to various scrapyards and junk planets by humans. The remaining few have gone cannibalistic.
Concept: Acid Scavenger Wandering the garbage wastes of Earth, these lizard-like creatures depend on select metals for growth and sustenance. Cutting chunks out of the waste with regurgitated acid forced through their tongue the creature swallows pieces whole. Excess minerals form growths on the skeleton which act as sensors, allowing the scavenger to feel and negotiate it's surroundings.
