Frequency signatures: Remora to Rock Cavy
Each card gives a species’ behavioural archetype, its frequency — how often it commits effort and how long each commitment lasts — and a waveform tracing that rhythm.
Frequency signatures
Each waveform traces one species’ working rhythm — where it spends effort, and where it waits. 2.327 species, A–Z; showing 1.753–1.776.
Remora
Dorsal Suction Disc
Attached • Carried • Low-burn
That makes it a low-frequency system: economical, patient and built around riding rather than producing movement.
Resplendent Quetzal
Whole-Swallowed Fruit and Seed Drop
Hovering • Plucking • Seasonal
Since feeding runs as a steady sequence of short sallies rather than long pursuits or rare strikes, it is a mid-frequency system.
Reticulated Python
A Heat Image Built From Lip Pits
Coiled • Thermal • Patterned
That makes it a bimodal system: prolonged thermally-guided waiting and a very fast strike.
Reticulated River Stingray
Substrate-Matched Disruptive Net
Settled on sand • Net pattern breaking the edge • Feeling for worms
Because everything runs slowly across a river bottom, it operates as a low-frequency system.
Rhinoceros
Bulk Forage Behind a Keratin Horn
Feeding • Wallowing • Marking
That makes it a bimodal system: slow bulk feeding and brief defensive charges.
Rhinoceros Hornbill
Sealed-Cavity Fig Delivery
Commuting • Provisioning • Reliable
Because the whole system depends on a repeated dependable circuit rather than reserves or bursts, it is a mid-frequency system.
Rhinoceros Iguana
Horned-Snout Threat Posture
Basking • Grazing • Dry forest
Because the whole system runs slowly, it is a low-frequency system.
Rhinoceros Rat Snake
Vine-Mimic Branch Drape
Draped • Green • Unhurried
Because the animal spends almost nothing and earns its living by being mistaken for vegetation, it is a low-frequency system.
Rhinoceros Viper
Wet-Litter Pattern Ambush
Coiled • Patterned • Near-static
Because near-zero waiting supports one overwhelming commitment, this is a bimodal system.
Ribbon Eel
Burrow-Anchored Sway Ambush
Anchored • Sampling • Cheap
Because the animal spends almost nothing on locomotion and earns its food by waiting in place with a very small maintenance bill, it is a low-frequency system.
Ribbon-tailed Astrapia
Ribbon Drag Display Engine
Burdened • Careful • Conserving
That combination of burdened conservation in daily life and explosive show during mating makes this a bimodal system with a low baseline and a high-frequency display mode.
Rice Grasshopper
A Grasshopper That Swims
Life spent on rice stems standing in water rather than on dry ground • The insect swimming when it falls in and climbing back onto a stem rather than drowning • Eggs laid in the raised bunds and drier margins above the waterline, so the vulnerable stage is never submerged
Because activity is continuous, it operates as a mid-frequency system.
Rifleman
Spiralling Up Every Trunk All Day
Spiralling • Probing • Relentless
That makes it a mid-frequency system: a steady, repetitive working rhythm with no slow or explosive phase.
Ring-billed Gull
A Gut That Takes Anything
Working whatever is briefly abundant • Learning where and when it appears • Moving on when it stops
Since opportunities turn over within days, it operates as a mid-frequency system.
Ring-necked Dove
Drinking Without Lifting the Head
Putting the bill into water and drawing continuously • Emptying a puddle in seconds without straightening up • Leaving the water almost immediately
Since drinking and feeding recur through the day, it operates as a mid-frequency system.
Ring-tailed Lemur
Scent-Loaded Tail Flag
Troop • Marking • Daily
Because troop coherence is maintained by continuous signalling and repeated daily routine, it is a mid-frequency system.
Ring-tailed Vontsira
A Generalist on Floor, Trunk and Stream
Foraging • Climbing • Opportunistic
Because it is built around steady opportunistic foraging, it is a mid-frequency system.
Ringed Seal
A Snow Room Above the Hole
Scraping holes open • Diving • Hollowing a chamber in a drift
This is a low-frequency system.
Ringtail
Hind Feet That Turn Right Round
Climbing • Counterweighted • Reversible
That makes it a mid-frequency system: continuously active in three dimensions rather than fast in one.
Rivoli's Hummingbird
High-Altitude Hover Engine
Explosive • Precise • Hovering
The system therefore depends on a high-frequency hover-and-dart mode coupled to a contrasting low-frequency resting mode that keeps the engine from burning out, making it a bimodal pattern built around explosive precision sustained by deep stillness.
Roadside Hawk
Hunting the Line Between Habitats
Perching on exposed posts, wires and low branches along the boundary of forest and open ground • Watching the cleared side while remaining in cover on the wooded side • Dropping short distances onto lizards, large insects and small vertebrates crossing that boundary
Because hunting is continuous, it operates as a mid-frequency system.
Roan Antelope
Ruined by Making the Land Better
Grazing tall poor grass • Watching • Living at low density
Steady grazing and vigilance makes this a mid-frequency system.
Robust Ghost Pipefish
A Drifting Leaf with a Pipette Snout
Hovering • Camouflaged • Ambushing
Because it is built on stillness, disguise and brief ambush strikes, it is a low-frequency system.
Rock Cavy
Cliff-Crevice Watch Network
Anchored • Sheltered • Watching
Because their survival depends on spending most of their time in a cautious, shelter-anchored state and occasionally converting that into a rapid collective dash, the rock cavy operates as a bimodal system with a low-frequency watch-and-feed mode and a high-frequency alarm-and-retreat mode.
