Frequency signatures: Diving Bell Spider to Driver 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 649–672.
Diving Bell Spider
Submerged Silk Air Chamber
Rhythmic • Maintained • Underwater
This produces a mid-frequency system: a stable underwater base sustained by rhythmic maintenance and ongoing, repeatable cycles rather than rare deep reserves or explosive bursts.
Dobsonfly
Mandibles Too Long to Bite With
Larval • Aquatic • Predatory
That makes it a bimodal system: a long capable aquatic stage and a short ornamental terrestrial one.
Domestic Canary
Seasonally Rebuilt Song Nuclei
Singing through the breeding season • Growing the brain regions that produce it • Shedding them again after
Since singing and feeding run together through the day, it operates as a mid-frequency system.
Domestic Cat
The Patient Opportunist
Calm • Watchful • Rhythmic
The cat is therefore a bimodal system: cruise quietly, then act fast when the opening is right.
Domestic Dog
Human-Gaze Attunement
Watching the face • Following the point • Checking back
Because the system is a continuous, cheap and unbroken reading of another species' attention, it operates as a mid-frequency system.
Domestic Donkey
Arid-Budget Load Carrying
Walking under load • Stopping to assess • Refusing to bolt
Since every process is slow, economical and built for a long horizon, it operates as a low-frequency system.
Domestic Duck
Feathers Zipped Into a Sheet
Barbules along each feather barb carrying hooks that interlock with the barbs beside them • The bird drawing each feather through the bill to re-zip separated barbs and spread oil from the preen gland • The plumage forming a continuous surface that water cannot pass through, with dry insulating down beneath
Because preening is continuous, it operates as a mid-frequency system.
Domestic Ferret
Long Spine, Fast Gut, Deep Sleep
Sleeping • Enclosed • Conserving
That makes it a bimodal system: long, deep sleep and short, intense active bursts.
Domestic Goat
Lip-Tested Browse Sampling
Reaching • Mouthing • Moving on
Because the sampling is continuous and repeated all day, it operates as a mid-frequency system.
Domestic Goose
A Bill That Shears Grass
Gripping grass between serrated bill edges and tearing with a head movement • Passing it through a short gut very quickly • Feeding for most of the daylight hours to compensate
Since bites recur every few seconds, it operates as a mid-frequency system.
Domestic Horse
Hindgut-Fermenting Standing Engine
Grazing most of the day • Fermenting behind the small intestine • Dozing on locked legs
Since intake and fermentation run continuously, it operates as a mid-frequency system.
Domestic Pig
Rooting Disc Substrate Search
Driving the snout disc into ground • Reading what is turned up • Wallowing to shed heat
Since rooting runs through the day, it operates as a mid-frequency system.
Domestic Pigeon
Homing on Several Maps
Reading the sun's position against an internal clock • Sensing magnetic field and low-frequency sound • Following remembered landmarks near home
Since orientation is corrected continuously, it operates as a mid-frequency system.
Domestic Rabbit
Ears That Listen and Cool
Rotating each ear independently • Scanning almost the full circle by eye at the same time • Shedding heat through the same ear surface
Since scanning runs continuously, it operates as a mid-frequency system.
Domestic Sheep
Distributed Flock Vigilance
Grazing head-down • Watching sideways • Moving as one
Because the watching and the feeding happen simultaneously, it operates as a mid-frequency system.
Domestic Turkey
Heads Down, Heads Up, Flock-Wide
Foraging • Scanning • Flocking
That makes it a bimodal system: steady vigilant foraging broken by brief flock-wide alarms.
Double-crested Cormorant
Wettable Plumage, Spread Wings
Diving • Pursuing • Sinking
That makes it a bimodal system: productive underwater work and a mandatory recovery period.
Downy Woodpecker
Rigid-Head Signal Drumming
Working thin stems • Drumming a resonant branch • Listening for the reply
Because that day is steady and repeated, it operates as a mid-frequency system.
Dragon Moray
Curved Fangs Waiting in a Reef Hole
Sheltering • Watching • Pumping
The system is bimodal: LOW waiting in shelter and HIGH strikes.
Dragonface Pipefish
Slow Line, Instant Snout
Creeping • Banded • Aligned
That makes it a bimodal system: slow, concealed creeping and a single explosive strike.
Dragonfly
A Jaw Fired Hydraulically
Waiting motionless on the bed of a pond as a nymph • Firing a hinged labium forward on hydraulic pressure • Pulling the prey back to the mouth in a fraction of a second
Since strikes recur in milliseconds, it operates as a high-frequency system.
Drain Fly
Larvae Inside the Slime Layer
Developing as larvae inside the gelatinous biofilm on the inside of drains • Breathing through a siphon that reaches the surface of that film • Grazing the bacteria and organic matter the film is made of
Since generations turn over in weeks, it operates as a high-frequency system.
Drill
Massed Ground Troop Movement
Massed • Ground-based • Daily
Because movement and feeding run as a steady daily cycle, it is a mid-frequency system.
Driver Ant
Pheromone Column Engine
Column • March • Sweep
The system therefore has a mid-frequency backbone of coordinated marching, with high-frequency surges layered on top when cues demand concentrated force, making it a bimodal pattern of steady organization plus triggered swarm bursts.
