Frequency signatures: Pyrenean Brook Newt to Red Ant
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 1,657–1,680.
Pyrenean Brook Newt
Flattened Torrent Clamp
Clamped • Cold • Long-lived
Because persistence in a demanding niche replaces speed and turnover, it is a low-frequency system.
Pyrenean Desman
Nocturnal Stream Tactile Swimmer
Rhythmic • Tracking • Forager
Because its whole system is built around this steady, touch-led tracking of hidden pathways in moving water, the Pyrenean Desman is best understood as a single, mid-frequency foraging engine.
Quenda
Cone Pits That Catch Litter
Probing • Digging • Moving on
That makes it a mid-frequency system: small repeated disturbances whose value accumulates in the soil rather than in the animal.
Quokka
Tameness Is Absence of Predators
Browsing at dusk • Resting in scrub • Not running away
Slow, nocturnal and conservative, this is a low-frequency system.
Raccoon Dog
Autumn-Fat Winter Dormancy
Foraging • Omnivorous • Fattening
That makes it a bimodal system: a broad active earning phase and a low dormant spending phase.
Racket-tailed Roller
A Display That Risks
Climbing steeply and then diving with the wings half closed • Rolling and tumbling through the descent so the flight is barely controlled • Pulling out close to the ground while calling, with the elongated tail rackets streaming behind
Because displays are seasonal, it operates as a low-frequency system.
Radiated Tortoise
Century-Scale Deferred Maturity
Slow • Long-lived • Late-breeding
Because everything runs at a very low rate, it is a low-frequency system.
Raggiana Bird-of-paradise
Canopy Lek Display Engine
Rhythmic • Site-faithful • Social
That makes the Raggiana Bird-of-paradise a bimodal system: a mid-frequency, site-faithful rhythm that supports a high-frequency, disciplined display burst.
Rail-babbler
Walking the Rainforest Floor Unseen
Walking • Gleaning • Secretive
That makes it a single-mode system: steady, secretive foraging on foot across the forest floor.
Rainbow Bee-eater
Sting Removed Before Swallowing
Catching • Beating • Disarming
That makes it a mid-frequency system: a steady repeating cycle in which every item has to be handled before it can be used.
Rainbow Crab
Land Animal Tied to Sea
Living in deep burrows inland, breathing air through modified gill chambers kept moist • Carrying eggs until they are ready and then migrating to the shore to release larvae into seawater • The larvae developing entirely in the sea before returning as juveniles to colonise land again
Because the cycle is annual, it operates as a low-frequency system.
Rainbow Lorikeet
A Tongue Tipped With Brush
A tongue tipped with erectile papillae that rise into a brush when extended • Sweeping nectar and pollen out of flowers rather than crushing seed • Moving between flowering trees as different species come into bloom across the year
Because feeding is continuous through the day, it operates as a mid-frequency system.
Rainbow Runner
A School That Reads as One Surface
Schooling • Flashing • Fast
That makes it a high-frequency system: continuously fast and collectively protected.
Rainbow Scarab
Tunnels That Pack Dung Into Brood Balls
Tunnelling • Provisioning • Recycling
It is a SINGLE MID system of steady seasonal work.
Rainbow Stag Beetle
Years in Rotting Wood, Weeks of Jaws
Tunnelling • Wood-feeding • Growing
That makes it a phase-change system: a long larval stage and a short, contest-driven adult stage.
Rainbow Trout
Seam-Held Drift Interception
Holding the seam • Reading the drift • Taking and returning
Because a continuously held position is worked by a constant fine rhythm of interceptions, it operates as a mid-frequency system.
Rainbowfish
Flashing Colours in a Sunlit School
Schooling • Grazing • Surface-feeding
The system is bimodal: coordinated schooling with brief bursts of display.
Rakali
Toads Flipped and Hearts Removed
Swimming the margin • Carrying prey ashore • Dissecting it precisely
Continuous nightly hunting makes this a mid-frequency system.
Ram’s Horn Squid
Gas Chambers in a Coiled Inner Shell
Hovering • Buoyant • Midwater
That makes it a bimodal system: near-weightless hovering and a regular daily vertical migration.
Ray
Breathing From Above While Buried
Lying flat under sand with only the eyes and two openings on the upper surface exposed • Drawing clean water in through those spiracles behind the eyes rather than through the mouth below • Passing it over the gills and out beneath, so respiration continues without disturbing the sand or the disguise
Because a buried ray is nearly motionless, it operates as a low-frequency system.
Razorbill
The Same Wing in Two Fluids
Flying • Marginal • Fast
That makes it a bimodal system: marginal costly flight and deep sustained wing-powered diving.
Razorfish
Swimming Head Down Among Spines
Holding the body vertical with the snout pointing at the seabed • Hovering in synchronised groups between the spines of a sea urchin • Moving as a unit while keeping the same orientation
Since adjustments are continuous, it operates as a mid-frequency system.
Red Admiral
Sewing a Roof From Nettle
Drawing a nettle leaf over itself and stitching the edges with silk • Feeding on the inside of that closed tent while hidden • Abandoning it and building a larger one at each successive stage
Because construction repeats through the stages, it operates as a mid-frequency system.
Red Ant
Alarm Chemicals That Summon
Releasing volatile alarm compounds from head glands on contact • Drawing nestmates toward the source within seconds • Stinging or spraying acid once they arrive
Since the signal rises and decays within seconds, it operates as a high-frequency system.
