Frequency signatures: African Pygmy Kingfisher to Amber Snail
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 25–48.
African Pygmy Kingfisher
Low Perch, Long Watch, Short Strike
Perching • Watching • Still
That makes it a bimodal system: patient perch-watching and sudden short strikes.
African Rock Python
Pressure Held Until the Heart Stops
Coiled • Digesting • Waiting for months
That is a bimodal system of low-frequency waiting and a high-frequency kill.
African Sharptooth Catfish
Trees of Tissue Inside
A pair of branched tree-like structures above the gill chambers, densely supplied with blood and open to the air • Air gulped at the surface held against that huge folded surface for oxygen uptake • The fish surviving in water with almost no oxygen and crossing wet ground between pools when one dries
Because surfacing is continuous, it operates as a mid-frequency system.
African Wild Dog
Sustained Cursorial Wearing-Down
Resting • Social • Most of the day
Because the system needs both the long social rest and the sustained pursuit, it is bimodal.
Agile Wallaby
Tendons That Give Back What They Take
Hopping • Elastic • Cheaper Faster
That makes it a mid-frequency system: steady, rhythmic and unusually economical.
Agrarian Sac Spider
A Silk Bag, No Web
Building a closed silk sac in a rolled leaf, a corner or a fold of cloth • Spending the day sealed inside it • Hunting on foot at night with no web at all
Since hunting recurs nightly, it operates as a mid-frequency system.
Aldabra Giant Tortoise
Heat-Limited Grazing Window
Grazing • Shading • Century-scale
Because the system runs on short daily windows inside a very long life, it is a low-frequency system.
Alderfly
An Adult That Cannot Feed
An aquatic larva with lateral abdominal gills, hunting small invertebrates in the silt of slow water for one to two years
The division is architectural rather than behavioural, so it operates as a bimodal system.
Alligator Gar
Scales Studied as Armour Material
Hanging motionless • Grabbing sideways • Rarely moving far
This is a low-frequency system.
Alligator Snapping Turtle
Worm-Lure Tongue Twitch
Settled • Gaping • Hours
Because a near-zero cost lure supports one instantaneous capture, this is a bimodal system.
Alpaca
Herd Contact Humming
Humming • Grazing • Grouped
That makes the alpaca a mid-frequency system: rhythmic, social and organised around keeping a group aligned at very low cost.
Alpine Chough
Social Updraft Acrobatics
Rhythmic • Social • Exploratory
Because their survival depends on this ongoing, shared exploration rather than on rare ambushes or long fasting, their system runs as a mid-frequency rhythm: continuous, social, and cyclic rather than slow-reserve or single-burst based.
Alpine Ibex
Climbing a Dam Wall for Salt
Grazing • High • Unpursued
That makes it a bimodal system: steady high-altitude grazing and a distinct mineral-seeking climb.
Alpine Marmot
Hibernating as a Family
Grazing alpine meadow through a short summer • Building fat and maintaining a shared burrow • Posting sentries and whistling at raptors
Applying the structural test, these are two physiologies, making it a bimodal system.
Alpine Musk Deer
Grown Once, Never Shed Again
Browsing • Scent-marking • Keeping the same weapon
Solitary, secretive and slow, it is a low-frequency system.
Alpine Newt
Some Never Leave the Water
Aquatic • Coloured • Breeding
That makes it an adaptive system: the operating state is selected by conditions rather than fixed.
Alpine Salamander
Years of Pregnancy, No Pond Needed
Emerging in damp weather • Feeding slowly • Carrying young for years
Everything about this is a low-frequency system.
Alpine Swift
Half a Year Without Landing
Airborne • Hawking • Continuous
That makes it a bimodal system: continuous aerial feeding and a crevice-bound breeding phase.
Amano Shrimp
Larvae That Need the Sea
Living and breeding as adults in fresh water • Releasing larvae that drift downstream into brackish water • Producing postlarvae that migrate back upstream months later
Since the cycle is annual, it operates as a low-frequency system.
Amazon Milk Frog
Calling From Inside the Cavity
Clinging • Calling • Holding
That makes it a low-frequency system: patient, cheap to run, and built entirely around one small hidden container.
Amazon River Dolphin
Unfused Neck Among Drowned Trees
Weaving • Flooded-forest • Probing
That makes it a phase-change system: slow flooded-forest weaving and low-water channel hunting.
Amazon Sailfin Catfish
Plated Against Swallowing
The whole body covered in overlapping bony plates rather than scales • Rigid spines in the pectoral and dorsal fins that lock outward when the fish is seized • Predators and birds unable to swallow or process it, so the fish survives attacks that would kill an unarmoured one
Because the defence is passive and continuous, it operates as a low-frequency system.
Amazonian Manatee
Flood-Season Feast, Dry-Season Fast
Grazing • Flood-season • Fattening
That makes it a bimodal system: flood-season grazing on floating meadows and a long dry-season fast in deep water.
Amber Snail
A Parasite Driving Eye Stalks
Ingesting flatworm eggs from bird droppings on vegetation • The parasite growing broodsacs that push into the snail's eye stalks and pulsate there • The snail moving into open sunlight and exposed leaves instead of hiding, until a bird takes it
Because the cycle runs across seasons, it operates as a low-frequency system.
