Name	Biomes	Description
Amphora Sponge		Symphon amphora — vase-shaped sponge that creates breathable air pockets in its central cavity.
Angel Comb		Bloom-category flora that grows in dense fans of pale, branching filaments. Found in the Blighted Coral biome.
Bloom Canker		Diseased Bloom-flora growth. Spongy, pale, and obstructive. Destroyed by Sonic Resonator or Feedback Resonator blasts.
Branching Coral		Tall, branching coral that anchors much of the Blighted Coral and Graveyard reef structure.
Cabbage Shootroot		Shootroot cabbage — robust bottom-dwelling starfish-relative. Similar in body plan to extinct blastoids (Paleozoic echinoderms). Most common Shootroot variant — visually dominant across the Shallows floor.
Cage Gorgon		Gorgon thalamiskos — cage-like predatory soft coral with a hollow lattice that traps small prey inside. Found in the Shallows.
Cherimoya Rotsac		Rotsac cherimoya — collects alcohol from decay and stores it as creamy flavored mucus. Yes, it is edible. Yes, it is unsettling.
Coral Dome		Coral geodesica — the defining geodesic-dome coral that gives the Shallows its silhouette.
Cradle Shootroot		Shootroot cunabulum — basket-shaped starfish-relative. Hosts the Lucifer Rotsac vine.
Curtain Gorgon		Gorgon aulaia — Venus-fan-like predatory soft coral with broad sweeping curtains. Largest of the Gorgon group. Found in the Leadzone biome.
Deepwing Egg Clump		Clutch of Deepwing Brooder Leviathan eggs. Massive, glowing, anchored to vent walls.
Donut No Worms		Empty Raion donut variant. The worms have vacated; the sponge structure remains.
Donut Of Worms		Raion donut — anemone-shaped sponge inhabited by predatory worms. The worms strike when prey enters the central hole.
Dragon S Scale Coral		Coral dragonscale — overlapping plated coral with a hot base and cold lip. Uses metabolic temperature differential to drive growth.
Feather Kelp		Feather-frond kelp species native to the Shallows — the default kelp silhouette and the visual signature of the starter biome. Hand-harvest fronds for Fibrous Pulp.
Freesia Flower		Flower-stalked Shallows flora with a distinctive elongated stalk and brightly-colored crown. Harvested by hand from the stalks. One of three primary Fibrous Pulp sources in the Shallows (alongside Cradle Shootroot and Feather Kelp).
Gateway Spire		Anomalous spire-like structure of uncertain biological vs constructed origin. Categorized under Anomalies / Structures.
Hecaton Tunic		Hecaton tunic — named for the hundred-handed myth. Exhibits competitive sex differentiation.
Listening Gorgon		Gorgon kryphakous — dull olive filaments that sway with current. Named for its apparent 'listening' posture.
Macaron Sponge		Symphon macaron — small, layered sponge with a flat disc profile. Common across the Shallows; one of the first sponges new players encounter. Visually recognizable by its stacked-disc silhouette, like its namesake pastry.
Mimic Pylon		Pyloraptor mimic — predatory kelp mimic. Looks like Feather Kelp until you brush it, then discharges an electric shock.
Oxygen Tunic		Tunic aeolian — splits seawater into H₂ (food) and O₂ (released). One of the most important survival organisms in the Shallows.
Pebbled Sporal		Sporal psephos — sponge/coral chimera with a distinctive pebbled surface texture. Found in the Anemone Hills biome. Taxonomically unusual: exhibits traits of both sponge and coral phyla simultaneously.
Radiator Coral		Anchors on hydrothermal vents and uses the temperature gradient for metabolism. Looks like a heat exchanger.
Tallshroom		Hyphen tallshroom — chitinous tall stalk flora. No known terrestrial analog. Distinctly non-fungal despite the 'shroom' name — the chitinous stalk is closer to an arthropod exoskeleton than mushroom tissue.
Toxic Sponge		Symphon achlys — 'sponge of dying mist'. Central node of a necrobiome — the keystone organism of the Leadzone biome's death-themed ecology.
Whip Gorgon		Gorgon mastix — whip-like soft coral with a single long flagellum. Found in Tufa Towers biome. Smaller than its Gorgon-group cousins (Curtain, Cage, Listening, Noon) but more mobile-looking due to current-driven whip movement.
