Frequency signatures: Dromedary Camel to Eastern Gray Squirrel
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 673–696.
Dromedary Camel
Tolerated Drift
Slow • Drifting • Tolerant
That makes it a low-frequency system: slow, tolerant and built to let conditions swing rather than to resist them.
Dugong
Rhizome-Ploughing Muzzle
Ploughing • Slow • Long-lived
Because a large animal is supported by continuous low-intensity grazing on a long horizon, it is a low-frequency system.
Dumbo Octopus
Fin-Hovered Whole-Prey Swallowing
Flapping two ear-like fins • Hovering above the mud • Swallowing prey entire
Because every process is slow, continuous and shaped by an environment that never changes, it operates as a low-frequency system.
Dung Beetle
Rolling a Ball Away Straight
Cutting a ball from a fresh dung pat within minutes of it falling • Rolling it away backwards while navigating by the sky • Burying it before any of the competitors arriving at the pat can take it
Since rolling is continuous work, it operates as a high-frequency system.
Dusky Dolphin
Leaping to Bring Others to the Ball
Herding • Circling • Compressing
That makes it a bimodal system: coordinated herding and a loud signalling behaviour that supports it.
Dusky Gopher Frog
Borrowed Burrow and Ephemeral Pond
Sheltered • Borrowed • Most of the year
Because the animal runs a long sheltered state and a brief aggregated one and requires both, it is a bimodal system.
Dusky Leaf Monkey
Fermenting Before the Stomach Acid
Browse • Sit • Ferment for hours
The cost is a diet that releases energy slowly, which is why the days are long, still and quiet: a low-frequency system.
Dusky Lory
Hundreds Moving as One Body
Flocks of hundreds and occasionally thousands moving together between flowering trees • The whole group arriving, stripping a tree of blossom and leaving together rather than dispersing • Individuals gaining nothing by staying behind because a stripped tree offers nothing and the next is found collectively
Because arrivals and departures recur constantly, it operates as a mid-frequency system.
Dusky Pademelon
Runways Only It Knows
Tunnelling • Feeding out • Slipping back
Repeated short excursions from cover makes this a mid-frequency system.
Dusky Sleeper
Root-Tangle Daylight Refuge
Hidden • Still • Ambushing
Staying put in one refuge, spending almost nothing on movement and letting prey arrive keeps its output flat and cheap, and that conserving pattern is what makes it a low-frequency system.
Dwarf Caiman
Armour Front, Back and Eyelid
Submerged • Plated • Unspending
A long cheap wait paying for one committed snap makes this a bimodal system, low-frequency in the water and high-frequency at the strike.
Dwarf Cassowary
Montane Fruit-Fall Circuit
Walking • Swallowing • Depositing
Because the system converts steady walking and continuous modest intake into dispersal, it is a mid-frequency system.
Earless Monitor Lizard
Transparent Eyelid Window
Submerged • Shut-eyed • Nocturnal
Because nothing about the animal happens at any speed, it is a low-frequency system.
Earwig
A Mother Cleaning Her Eggs
Laying a clutch in a chamber under cover • Turning and licking each egg repeatedly through weeks of incubation • Guarding the young through their first instar
Since the cycle runs once a year, it operates as a low-frequency system.
East African Oryx
Brain Kept Cool, Body Not
Storing heat by day • Grazing • Dumping it at night
Conservative and reserve-based, this is a low-frequency system.
Eastern Bettong
Tail-Carried Nest Bundle
Nightly • Digging • Housekeeping
Because the whole night is spent on steady digging and upkeep rather than on reserves or bursts, it is a mid-frequency system.
Eastern Box Turtle
Two Shell Lobes Swinging Shut
Foraging • Homebound • Unhurried
That makes it a bimodal system: a slow, long-lived foraging routine punctuated by brief, complete closure.
Eastern Boxelder Bug
Aggregated Overwinter Diapause
Feeding on seed • Scattered across the tree • Breeding through summer
Because a dispersed feeding season and a hormonally distinct aggregated winter are both necessary and neither is a version of the other, this is a bimodal system.
Eastern Chipmunk
Larder-Banked Winter Torpor
Filling pouches • Carrying • Stacking one chamber
Because a season of accumulation and a season of metered drawdown are each indispensable to the other, this is a bimodal system.
Eastern Collared Lizard
Bipedal Boulder Sprint
Basking • Perched • Watching
That makes it a bimodal system: a long low-cost basking watch and a brief, temperature-limited burst.
Eastern Cottontail
Freeze, Then the Learned Line
Frozen • Flattened • Unseen
That makes it a bimodal system: near-total stillness and a short, sharp, pre-mapped run.
Eastern Emerald Elysia
Chloroplast Harvest Body
Steady • Sun-fed • Frugal
Because its whole design favors slow acquisition, internal storage, and gentle ongoing use of a borrowed energy system, Elysia chlorotica operates as a single, strongly low-frequency system.
Eastern Glass Lizard
Two Thirds Detachable Tail
Slipping • Hunting • Shedding
Continuous low searching through cover makes this a mid-frequency system.
Eastern Gray Squirrel
Scattered Single-Nut Caching
Burying one nut per hole • Faking caches when watched • Recovering by memory and smell
Since the caching and recovery run continuously at one tempo, it operates as a mid-frequency system.
