Taxonomy

Kingdom Animalia, Fauna

Ephron life is organized across two kingdoms: fauna and flora. Each class or division is defined by a shared set of diagnostic traits, the biological minimum required for membership. Below each, species are grouped into families where relationships have been established. Families marked "pending" have no confirmed genus grouping yet.

I. Mammalia

Common Names: Mammals, Beasts

Endothermic. Bodies covered in fur or hair. Young are born live and nursed via mammary glands. Skeletal structures are low-density, optimized for Ephron's 0.76g gravity. Completely independent of Earth's mammalian lineage but satisfying the same reproductive and metabolic criteria.

Family Primatus

Large-bodied, primate-form Mammalia with dexterous forelimbs, complex social structures, and documented sapience or sapience-adjacent cognition.

Family Feroxalaceros

Engineered Mammalia: feline-Selvakir hybrids created by human scientists, now a fully independent species after centuries of isolation and natural selection on Ephron. Classic Felinae traits have diluted to near-absence; what remains is a distinct Ephron-only species with horns, morphic cores, and high Eilan sensitivity. Cultural documentation is extensive and handled separately.

Undocumented

II. Pennaeformis

Common Names: Birds, Plumes

Lightweight, semi-hollow skeletal structures. Bipedal stance. Epidermis covered in branching feather-like structures (pennae) optimized for aerodynamic flight in Ephron's dense atmosphere. Achieves scales impossible on Earth: wingspans of six meters or more are documented.

Family Ludex

Enormous, apex-predator Pennaeformis defined by conflict-sensitive Eilan attunement rather than conventional predatory hunger.

Family Pending

Undocumented

III. Silicosquama

Common Names: Reptiles, Slithers

Ectothermic, requiring external heat sources for metabolic regulation. Dermis is covered in dry, overlapping, self-shedding keratinous or silica-composite scales that prevent moisture loss. Extremely resilient in arid zones. Many species have adapted to Ephron's 30-hour day by concentrating activity during the midnight watch.

Family Pending

Undocumented

IV. Glanduloderma

Common Names: Amphibians, Slimes

Semi-permeable, glandular skin lacking scales or hair, requiring constant moisture for cutaneous respiration. Reproduce via gelatinous, amniotic-shell-free eggs. Highly sensitive to environmental toxins and Eilan fluctuation, making them reliable ecological indicators.

Family Resonoderm

Defined by overdeveloped vocal sac anatomy producing calls of extraordinary range and volume. Arboreal and wetland variants documented.

Family Reflectoderm

Defined by light-reflective dermal proteins forming a metallic dorsal surface. Strongly Eilan-receptive; preferentially colonize imprint-dense ground.

Family Pending

Undocumented

V. Chitinoconcha

Common Names: Bugs, Chits

Invertebrate organisms defined by a hardened, segmented exoskeleton or carapace and jointed appendages. Grouped by protective shell rather than limb count, uniting six-, eight-, and multi-legged forms under one class. Many species display intense synchronized bioluminescence, particularly during Nyxara's 60-day fullness cycle.

Family Scaventor

Defined by powerful grinding mandibles, high disease tolerance, and carrion-specialist feeding behavior.

Family Supercolonia

Defined by superorganism colony structure, millions of coordinated individuals functioning as a single distributed entity.

Family Pending

Undocumented

VI. Mycozoan

Common Names: Fungal Fauna, Shrooms

A class defined by absolute biological symbiosis with Ephron's giant fungi. Bodies are a physical fusion of animal tissue and mycelial networks. Reproduction occurs not through eggs or live birth but through volatile spores that mature within bodily fluids. Includes everything from massive, slow-moving quadrupeds carrying full fungal ecosystems on their backs to microscopic circulatory parasites.

Family Mycoarchitecton

Defined by colony-scale growth around energy sources, eventually encasing and feeding upon them entirely. Sessile at maturity; functions more as a location than an organism.

Family Mycovertebra

Defined by complete dorsal colonization by a living fungal system, producing structural mimicry of free-standing flora so total it functions as passive defense.

Family Pending

Undocumented

Outside the biological taxonomy: Humanity (Hei) and Puppets are documented as social and civilizational categories rather than fauna entries. Arkafelari are classified under Family Feroxalaceros above but their cultural, societal, and historical documentation lives on their own pages.

Kingdom Plantae, Flora

Ephron flora is organized into three divisions. Division Viridantha covers non-woody vascular groundcover: grasses, herbs, ferns, vines, and flowering plants. Division Arborea covers woody, self-supporting flora achieving significant height. Division Mycota covers fungal organisms large enough to function as flora in the ecological record. A fourth grouping, Eilan-class, is used for organisms that resist standard divisional placement due to anomalous Eilan properties.

Plant taxonomy uses Division rather than Class at the top tier, and otherwise follows the same Family → Species structure as fauna. Scientific names are still being assigned; entries marked pending have common names only.

Division I, Viridantha

Common Names: Plants, Growth

Non-woody flora that photosynthesize and grow from root systems or surface anchors. Includes vascular and non-vascular forms such as all groundcover, herbaceous, and low-growing flora. The most species-dense division in the flora record. Organized into families by growth habit and structure.

Family Graminae (Grasses & Reeds)

Narrow-leafed, upright-growing plants with segmented stalks, producing edible seed heads or grains. Wind-pollinated. Primary grain sources for Arkafelari colonies.

Family Tuberosa (Tubers & Root Crops)

Plants defined by a dominant underground storage organ (tuber, taproot, or bulb) as their primary biological structure. Above-ground growth is secondary.

Family Muscinae (Mosses & Lichens)

Non-vascular or near-non-vascular organisms that anchor to surfaces rather than rooting in soil. No true stem, leaf, or seed structure. Tolerant of poor light and moisture extremes.

Family Filicinae (Ferns)

Vascular but non-flowering plants reproducing via spore. Defined by frond-form leaf structure: pinnate, translucent, or palm-divided. No seed production.

Family Ligantia (Vines & Creepers)

Trailing or climbing plants with no self-supporting structure. Defined by lateral spread along host surfaces, ground cover, or canopy anchoring.

Family Luminae (Bioluminescent & Moon-Reactive Flora)

Plants defined by active light emission or bloom cycles governed by celestial timing rather than season. Unique to Ephron; the trait is believed linked to Eilan sensitivity at the cellular level, though these organisms do not qualify for Eilan-Class placement.

Family Herbaceae (Flowering Herbs)

Upright, self-supporting, flower-bearing herbs that do not fit the structural criteria of any other groundcover family. The broadest groundcover grouping by species count.

Division II, Arborea

Common Names: Trees, Canopy

Woody, self-supporting flora achieving significant height through lignified trunk or stem structure. Reproduce via elevated seed dispersal. The structural backbone of Ephron's forest biomes; lifespans measured in decades or centuries.

Family Drupaceae (Fruit-Bearing Trees)

Trees producing fleshy, seed-containing fruit. Primary wild food source in forest biomes across all seasons.

Family Palmiforma (Palm-Form Trees)

Tall, unbranching trees with crown foliage. Coastal and equatorial distribution. Produce large fruit or drinkable liquid.

Family Robustia (Structural Hardwoods)

Dense-wooded trees defined by lignin-heavy trunk composition. Valued for timber and construction.

Family Lacrimosa (Weeping & Trailing Trees)

Trees defined by drooping branch structure and slow-seeping sap production. Preferentially colonize Eilan-dense ground; associated with funerary sites in Arkafelari tradition, though this is cultural observation rather than biological criterion.

Division III, Mycota

Common Names: Fungi, Caps

Fungal organisms of sufficient scale and ecological presence to function as flora in the surface record. Reproduce via spore rather than seed. Not photosynthetic, nutrient acquisition is through substrate absorption. Mycota documented here are free-standing organisms; fungal fauna that have fused animal tissue with mycelial networks are classified under Mycozoan in the fauna record.

Family Fungitrunca (Trunk-Forming Fungi)

Defined by self-supporting, bark-like rind growth achieving tree-scale heights. Generalist in habitat. The only documented Mycota family with confirmed arboreal-scale growth in Ephron's 0.76g gravity.

Undocumented

Eilan-Class Flora

Anomalous, Division Pending

A small grouping of organisms that resist clean placement in Viridantha, Arborea, or Mycota due to Eilan properties so active they constitute a defining biological trait rather than an incidental one. These plants do not merely accumulate or respond to Eilan: they direct, store, or exchange it in ways that blur the boundary between organism and Eilan phenomenon. Formal divisional placement is deferred until the mechanism is better understood.
