Species of Mundus: Arachnid Phractos
Introduction: The Phractos are a group of sapient arthropods who, through convergent evolution, developed hominin-like bodies. The Phractos are further divided into four classes: Arachnid Phractos, Crustacean Phractos, Myriapoda Phractos, and Insect Phractos.
The Arachnid Phractos are a group of arthropods most commonly identified by possessing eight ‘legs,’ although other appendages may be mistaken as legs. They primarily live on land, although a few species live near aquatic environments as well. About 18 orders of Arachnid Phractos exist such as Amblypygi Phractos, (True) Spider Phractos, and Scorpion Phractos. A few orders have gone extinct, such as the Haptopoda Phractos and Sacroptiformes Phractos.
Evolution: Similar to the evolution of Insect Phractos, whose origins are believed to stem from “ordinary” insects like the Veteris Armis, the origins of Arachnid Phractos are believed to stem from “ordinary” arachnids. These arachnids developed from ancient crustaceans about 380 MA, and the earliest known terrestrial ancestor for arachnids comes from the Trignotarbida order.
The Trignotarbida order were originally small creatures ranging from a few millimeters to a few centimeters in size. They lacked spinnerets and had a more simple body plan to modern arachnids. They lived on the ancient continent of Jearun, long before Yaquoris formed. However, as the Trignotarbida order evolved throughout the Silurian and asserted themselves as a carnivorous order, they began to develop heavy armor with spines and tubercles. This was combined with a development in their cranial capacity to better catch their prey, which forced their bodies to suit their increased brain size. This created a vicious cycle, and by the early Permian, the Trignotarbida order reached several inches in size and many of the known arachnid orders had sprung from them. Th
While the Trignotarbida order went extinct around 290 MA, their surviving descendant orders shared their similarly large brains continued to evolve and spread across Jearun and other ancient continents. While “ordinary” arachnids flourished in numbers far greater than the Phractos orders, and there were many evolutionary mistakes, reversals, and extinctions for the Arachnid Phractos along the way, by the formation of Yaquoris some 60 MA, most Arachnid Phractos orders reached an intelligence rivaling that of Insect Phractos.
Anatomy: While each order of Arachnid Phractos has unique physical traits, all Arachnid Phractos have several traits in common: all Arachnid Phractos either possess a form of tracheae or a book lung, they lack a pair of antenna and wings, their bodies are divided into two segments called the celphalothorax (their torso and head) and their abdomen, and they all possess eight ‘legs.’ All Arachnid Phractos range in size, with Spider Phractos having the greatest variety, but most species vary from 3 to 7 feet in height, 4-8 feet in length, and 4-10 feet in width. They can weight between 50 to 120 pounds.
An area of confusion for many people is that many Arachnid Phractos only possess six “legs.” This is technically true, because many Arachnid Phractos only possess six limbs for walking. What they fail to recognize, however, is that over the millennia, Arachnid Phractos have actually adapted their forelegs into a set of grasping limbs; these grasping limbs make up the lower set of arms for Arachnid Phractos. In a similar bout of adaptation, the pedipalps of many Arachnid Phractos also developed into grasping limbs, or the upper set of arms. While this adaption means that Arachnid Phractos have weaker balance than their “ordinary” counterparts, their grasping ability is equal to that of Insect Phractos. The lower set of arms are still called “legs” to recognize the arachnid lineage of Arachnid Phractos.
Similar to Insect Phractos, Arachnid Phractos have similar abilities to their “ordinary” counterparts. For example, Scorpion Phractos possess stingers that help them with ambushes and hunting, and claws for pinning prey. Spider Phractos can weave webs, and Whip Scorpion Phractos possess superhuman strength. However, these abilities aren’t directly proportional to their smaller counterparts: a Scorpion Phractos’ venom isn’t as potent, Spider Phractos need to produce more spider silk to hold their greater body weight and that of their prey’s, and Whip Scorpion Phractos aren’t as proportionally strong as ordinary Whip Scorpions.
Diet: Almost all Arachnid Phractos are carnivorous. While they do possess human-like jaws, their thin throats cannot ingest solid food larger than a half-dollar coin. As a result, most Arachnid Phractos digest food outside their bodies by bathing their meals in stomach acid and partially digesting it into a soft meat paste. They then chew the half-digested food particles with their jaws and mandibles before swallowing. Harvestmen Phractos are the only Arachnid Phractos capable of fully chewing and swallowing food in their bodies.
It is common for Arachnid Phractos to use venom to paralyze prey prior to digesting them to avoid dangerous struggles; this venom is designed to break down into harmless chemicals during the pre-digestion process to avoid harming the Pharctos themselves. It is also common for Spider Phractos to accidentally swallow their own silk during meals, which also safely breaks down to avoid clods of silk forming in their stomachs. The greatest complaint to ingested spider silk is sore throats and the silk’s unappetizing flavor of glue.
While modern Arachnid Phractos do follow the dietary habits of humans and Avesians by eating domesticated animals like chicken, pig, and cow, they have historically been known to eat any animal they can capture. Not only that, but Arachnid Phractos societies have been known to make other Phractos into livestock, such as the the Bristly Millipede Phractos; the only reason these actions weren’t considered slavery and mass cannibalism is because species like the Bristly Millipede have an intelligence more comparable to a monkey than a human. Husbandry like this, however, has fallen out of practice due to societal pressures from humans and Avesians; furthermore, with the advent of modern farming technology, Arachnids can eat “ordinary” insects en masse more efficiently than raising Bristly Millipedes for consumption. Nowadays, a common meal to an Arachnid Phractos is toast covered in meal worm paste and and sprinkled with cricket legs.
The Bristly Millipede Phractos is still occasionally eaten as a delicacy or as part of a ceremonial meal.
