Acid Anemone	Standard	Anthobrachia necrolei. A clonal stalk of large jellies, similar to Earth's stauromedusae. Each jelly remains moored to the stalk, rather than maturing into a free-swimming medusa. 1. Enormous size and hunger Rather than feeding on prey, the necrolei gathers dead matter from the seawater. The size and height of the stalk are directly related to the rate of death and decay up-current. 2. Acid-yielding metabolism The necrolei has adapted to low-oxygen seawater. It ferments much of the matter it collects in a central 'basket' stomach, a process which requires no oxygen and yields strong acids. The necrolei concentrates these acids around its eggs as a defense. Assessment: large numbers of necrolei in this region indicate a bloom, a population explosion caused by a flood of nutrients. This is a poor sign for the health of the ecosystem and perhaps for the state of the global climate. Produces egg clusters that can be processed into strong acid.

Axum Rebar Clump Deposit	Large Deposit	Large Deposit - Unknown
Celestine Deposits	Large Deposit	Large Deposit - Sonic Resonator / Drill
Celestine Nodes	Standard	Celestine (strontium sulfate, SrSO4). A crystalline mineral and useful source of strontium. Celestine dissolves quickly in seawater, but certain microorganisms synthesize it as a shell or ballast. Local deposits must be the skeletons left by dead colonies of these organisms. The colonies may have overgrown on an artificial strontium source, then died off when the source was removed. Strontium (Sr), element 38, is a soft and highly reactive metal with applications in radiothermal power generation. Strontium on this planet contains elevated levels of Strontium-90, a highly radioactive, bone-seeking isotope which poses a long-term health risk to human colonists. Strontium-90 is only produced in nuclear fission reactions. Assessment: do not ingest.
Cherimoya Rotsac Fruit	Standard	Standard - Break (Hand/Tool)
Copper Node	Breakable Node	Bacteria concentrate copper in low-light areas. Search cave roofs, overhangs, shadowed crevices.
Curtain Gorgon	Cuttable Flora	Gorgon aulaia. A soft, predatory coral akin to Earth's gorgonians, especially the Venus fan. 1. Sponge-coral moiety Like Earth's brown tube sponges (Agelas schmidti), soft corals on this world are a colony of coral polyps growing within a matrix of sponge tissue. In this specimen it is very difficult to distinguish the sponge's jellylike inner tissue (or mesohyl) from the soft coenenchyme which connects the coral polyps. 2. Ribbons of tissue The curtain gorgon forms a long, low-lying fan of tissue which catches prey. The curtain gorgon is an obligate predator and cannot survive on sunlight, but some specimens are colonized by chemotrophic bacteria which may provide the gorgon with extra energy. 3. Plasticized skeleton The gorgon's skeleton is chemically similar to PVC (polyvinyl chloride, an obsolete industrial plastic). Assessment: indicates the presence of plankton and other small sea life.
Freesia Plant (Cut For FIber)	Standard	Standard - Grown (Hand Pick)
Fulgurite Loose	Loose Pickup	Kagome optical fibers derived from shock quartz. Naturally occuring wires for light.
Gold Node	Breakable Node	Gold (Au), element 79. Shares many properties with copper and silver. Highly conductive and ductile. Can form atom-thin wires. Critical for corrosion-resistant electronics, especially in humid environmnents. Also useful for shielding spacesuits and spacecraft against heat. Rare—tends to sink to the core of planets during formation. If you cannot access the core of the planet, search for surface deposits formed by bacterial accumulation.
Lead Deposit	Large Deposit	Lead (Pb, element 82). A dense metal and the heaviest stable element. Found in many ores. Useful in construction alloys, ballast, radiation shielding, and some very large batteries. Due to this world’s high metallicity, lead plays an unknown but significant role in the biosphere. All indigenous organisms and water sources are tainted with lead. Lead can mimic other metals involved in human biology, replacing them in critical reactions. It is a devastating toxin. Long term exposure requires urgent chelation therapy. Take any possible steps to remove lead from your food and water supply. The presence of organolead compounds in the biosphere of Rakshasa played a major role in the breakdown of the expedition and the renewal of the Obraxis Principle.

Lithium	Loose Pickup	Lithium (Li), element 3. The softest and least dense of all metals. Often found dissolved in seawater or in pegmatite deposits, especially near thermal vents. Useful in lubricants, batteries, advanced glass, nano-welding, quantum physics, and anti-aging drugs. Also a budget air-cleaning element on spacecraft. Lithium’s role in this world’s biosphere is unknown. In humans it has historically been used as an antidepressant. Despite the advent of cognitive connectome therapy, lithium is still used as a folk remedy on some worlds, despite the risk of permanent side effects.

Plant Bulb	Standard	Standard - Grown (Hand Pick)
Plant Feeler	Farmable Plant	Tentatively Pyloraptor mimic. A predatory animal disguised as a leafy kelp. Discharges electrical shock when disturbed. 1. Cephalopod-like body Resembles an octopus or squid planted mantle-down in the seabed, with its arms spread to mimic kelp. Pouches of symbiotic bacteria between the arms allow it to photosynthesize. A beak at the center of its arms is plugged with mucus. 2. Electrical hunting The four arms contain electrocytes, organs which build up an electrical charge. When disturbed by prey, the electrocysts discharge, causing paralysis or death. It is unclear if the prey are directly eaten, or if they decompose in a garden around the mimic pylon. (Organisms which feed on external decay are known as saprotrophs.) 3. Implies kelp The pylon's cryptic aggressive mimicry of leafy kelp implies that kelp must exist on this world. Most species in Earths' oceans eat to survive, with primary production (the conversion of sunlight into biomass) carried out by plankton and algae. Leafy kelp were a late evolutionary development. 4. Cave mouth strategy Mimic pylons tend to cluster around sea cave entrances, perhaps to feed on organisms entering or leaving the caves. Alternately (and speculatively) they may have been planted there by another species to control access. Assessment: avoid contact to prevent injury. May mark cave mouths.
Prismatic Shell	Standard	Standard - Unknown
Quartz Node	Standard	Coral domes expel waste silica as they grow. Check the surface and interior of coral domes. In areas where domes do not grow, quartz may be located in sandy areas.
Quartz With Base	Standard	Standard - Unknown
Salt Node	Standard	Halite (NaCL), commonly known as salt. A critical nutrient and a favorite flavor in human foodstuffs. Nearly four percent of the alien seawater is dissolved salt—far higher than the concentration in human blood. Living things (even on this world) cannot survive this level of salt in their bodies. As a result, organisms spend a great deal of energy pumping salt out of their bodies. Some fish use a third of their metabolic energy to pump salt. A shortage of salt is equally dangerous. Hyponatremia causes hallucinations, seizure, coma and death (easily confused with other syndromes caused by exposure to this alien environment). Assessment: search for salt on sandy sea bottoms and around dead coral domes. Note: pools of salt-heavy brine may occur at the sea floor. Contact with this brine may cause seizures and death. Certain bacteria (halophiles) can thrive in these environments.
Silver Node	Standard	Silver (Ag), element 47. The most conductive and reflective of all pure metals. Silver nanoparticles are vital in both medical technology and nanoprinted circuits. Also important in modern nuclear reactors and high-efficiency solar panels. Silver accumulation in the body (from exposure in seawater and diet) can cause long term health effects ranging from blue skin to death. This world’s dissolved silver levels are unsafe for human habitation. Consult your Noetic Advisor to research optimal search areas.
Sulfur Deposit	Large Deposit	Large Deposit - Sonic Resonator / Drill
Sulfur Loose	Loose Pickup	Sulfur (S), element 16. A highly reactive nonmetal useful for chemistry, especially the production of acids, and an essential element for life. Historically known as brimstone, with applications in medication and fertilizer. Some organisms use sulfur in their metabolism, even in the absence of oxygen. These sulfur-reducing organisms can form the base of a food web in deep sea habitats. Assessment: search for elemental sulfur deposits near thermal vents or volcanic activity.
Tallshroom	Cuttable Flora	Hyphen tallshroom. A mysterious, chitinous life form with no clear terrestrial analog. 1. Hyphen Hyphens are colonies of hard-shelled hecaspids: shell-making algae. (Algae on this world descended from a star-like 'solarian' cell, while all animal life descended from an elongated 'polarian' cell.) Hecaspids in the colony align their shells into a column, forming tough armored threads, or hyphae. On Earth hyphae are characteristic of fungi, but it is not clear if an analogous group exists on this world. 2. Tallshroom The tallshroom is a complex organism with differentiated organs, but all its structures are fundamentally threadlike — hyphenated — and constructed of tough biopolymer akin to chitin. Gill-like structures along the flanks collect oxygen and chemistry from the water, fruiting bodies disperse reproductive cells, and the central body forms a sealed 'wellhead'. 3. Armored driller Tallshrooms drill their hyphae into the rock below, cracking open their own hydrothermal vents. The body captures the outflow of this vent, where bacteria convert minerals into energy. If the outflow becomes too hot or rapid, the tallshroom's drumlike top blows open, releasing the catastrophic overflow. 4. Viral history Like the mammalian placenta, the tallshroom's hyphae evolved in an explosion of retroviral inserts. These viral proteins are expressed in the tips of the drill fibers. Hyphae may have originally evolved as viral predators—inserting a symbiotic virus into armored life forms by growing on and cracking through their bodies. 5. Cousins Despite millions of years of evolutionary separation, the tallshroom shares elements of its body plan with the false fission drum Polymephycite tympanum, a fellow member of clade Scyllidae. It is unknown whether this represents convergent evolution, mimicry, or a viral gene transfer. Assessment: indicator of new evolutionary pathways unique to this world.
