Description
A Spectember art piece that took me most of the month to make. Showcasing a Batesian mimicry ring found in China some 7-10 million years in the future.
The northern snakeheads have diversified into several families of amphibious fish that are all highly successful in the Chinese subtropics. Overall, they now possess primitive feet derived from their pectoral fin.
One such species is the Violet Deathhead (Rutrumaput pharmaphyrous). A species of semi-aquatic and semi-fossorial snakehead that uses its shovel head to dig up a wide variety of prey. What makes the Violet Deathhead stand out is its iconic purple, black, and orange patterning used to warn predators of its potent venom-tipped rays.
The Violet Deathhead's infamy would spread throughout China's ecosystem. Its colors became an iconic warning of certain death. Something so iconic it spawned a variety of mimic species, all possessing the same patterns to ward off predators.
One of the first notable mimics isn't a snakehead or a fish altogether. But a sailfin lizard . Its ancestors rafted here from the Philippines during a particularly nasty southwest monsoon. They became so successful they spread across the entire continent.
This mimic species is known as the Shamfin Lizard (Zhonghydrosaurs purvexicauda). They are a species of arboreal herbivores with a slight tendency to feed on insects.
As their name implies, their tail takes on the same purple, black, and orange patterns used by the Violet Deathhead to present itself as such to trick predators. They even go as far as to develop fake eyespots on their back to match the model species' heads.
With as much speciation also comes the weight of extinction. And it is no different in this ecosystem as well. During this period, many species of Cranes and herons had to migrate away from China or go extinct altogether. However, this opens a new niche for an unexpected group of birds to flourish.
The second mimic species is the prism-winged Stiltit (Hydorbaino porphypteros). They are a species of wading piscivores that descend from the white-browed tit warbler .
They retained their ancestors' coloration but now for a new purpose. It's now within their underwing and patterned in the likeness of the Violet Deathhead's sail.
The third mimic species is the Mockfry Mawed Moth (Stekoprosteros mimeofry). They are species of flying pollinating moths that retain their proboscis into adulthood. They are surprisingly social and live in large flocks their whole lives. As their genus name suggests, their resting state has their forewings erected upward, unlike other moth species.
They possess similar colors and patterns to the Violet Deathhead but seem to mimic their species' young. The moths and fry are around the same size and live in large groups. Plus, Deathheads have their iconic coloring during their entire lives.
The final mimic species mentioned isn't a vertebrate or even an animal. Instead, the Fool's Death (Coleus teleinephos) is a species of Eudicot flowering plant. The stem of the Fool's Death grows into an arc, with the upper stalk resting in the giant leaves of the plant's base.
The Fool's Death's signature green and purple leaves allow it to mimic the patterns of the Violet Deathhead. And since their ranges overlap the most of all the mimics. The Fool's Death is surprisingly the most effective at being a mimic as it gets avoided most of any of the mimicking species.
