Frequency signatures: Highfin Dragonfish to Horned Screamer
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 1.081–1.104.
Highfin Dragonfish
Deep-Barbel Target Sensor
Drifting • Listening • Dim
That architecture — long passive sensing phases powered by the barbel, broken by quick, localized attack bursts — makes this a bimodal system combining a low-frequency surveillance mode with a high-frequency capture mode.
Himalayan Goral
Rubber-Rimmed Hoof Grip
Twice-daily • Grazing • Cliff-bound
Because it runs a regular, repeated daily cycle at moderate cost rather than storing or bursting, it is a mid-frequency system.
Himalayan Monal
Digging for Food Under Snow
Working alpine slopes with a short heavy decurved bill • Digging through soil and snow for tubers, rhizomes and insects • Occupying ground above the treeline where surface food is scarce
Since the cycle is annual, it operates as a low-frequency system.
Himalayan Snowcock
Walk Up the Slope, Glide Down
Walking • Digging • Covey
That makes it a bimodal system: slow uphill feeding punctuated by fast downhill escapes.
Himalayan Tahr
Wool-Undercoat Winter Buffer
Insulated • Stored • Enduring
Because the whole architecture stores in a brief window and draws down patiently across a long one, it is a low-frequency system.
Hirola
Preorbital Gland Scent Marking
Marked • Grazing • Open ground
Because grazing and marking run as a steady daily cycle, it is a mid-frequency system.
Hispaniolan Solenodon
Grooved-Incisor Venom Probe
Nightly • Probing • Methodical
Because value is extracted by steady methodical probing across hours rather than by reserves or bursts, it is a mid-frequency system.
Hoary Marmot
A Short Summer Paid For With Long Sleep
Feeding • Colonial • Watchful
This is a PHASE_CHANGE system: a MID summer phase of feeding and vigilance and a long LOW phase of hibernation.
Hoatzin
A Crop That Displaced the Flight Muscle
Eating leaves • Fermenting in the throat • Barely able to fly
This is a low-frequency system.
Hoff Crab
Bacteria Farmer on the Vent Gradient
Crowding • Farming • Positioning
Because it spends its life sitting in one thin zone of the vent gradient, the system is a low-frequency system.
Hog Badger
Snout as Sensor and Spade
Rooting • Sniffing • Advancing
Continuous undifferentiated working of the substrate makes this a mid-frequency system.
Hog Deer
Head-Down Grass Tunnel
Grazing • Ducking • Grassland
Because the system runs on steady grazing inside continuous cover, it is a mid-frequency system.
Honduran White Bat
Vein-Cut Leaf Tent
Small • Sheltered • Frugivorous
Because a very small energy budget is protected by built shelter rather than by activity, it is a low-frequency system.
Honey Badger
The Armored Counterstriker
Armored • Independent
That makes it bimodal: armor first, explosive response second.
Honey Possum
Living on What Flowers Give
Clambering • Licking • Pollinating
That makes it a bimodal system: steady nightly flower feeding and short energy-saving shutdowns.
Honeypot Ant
Desert Replete Pantry
Stored • Shared • Reserves
Because the whole system is built around dense reserves, slow turnover and careful communal withdrawal, this is a strongly low-frequency, living-pantry system.
Hooded Seal
A Nose Inflated Into a Signal
Diving • Solitary • Oceanic
The system is bimodal: a long low-frequency foraging mode and a short, explosive breeding and display mode.
Hooded Vulture
Slender Bill, Second in Line
Soaring • Arriving late • Picking
Continuous soaring and social feeding makes this a mid-frequency system.
Hoolock Gibbon
Paired Morning Canopy Duet
Calling • Swinging • Morning
Because the system runs on a daily call and steady travel, it is a mid-frequency system.
Hoopoe
A Bill That Opens Underground
Probing • Prying • Foul-nested
That makes it a mid-frequency system: steady, methodical probing across open ground.
Horned Grebe
Legs at the Back, Feathers in the Stomach
Diving • Lobed • Committed
That makes it a mid-frequency system: steady repeated diving with nothing held back for land.
Horned Nerite Snail
Larvae Down, Adults Up
Adults living and breeding in fresh water well upstream, laying egg capsules on rocks • Hatched larvae carried downstream and out to sea, where they develop in the plankton for weeks • Settled juveniles returning to the river mouth and then climbing upstream over months, sometimes in enormous aggregations
Because the cycle is annual, it operates as a low-frequency system.
Horned Puffin
Backward Spines Holding a Row of Fish
Flying • Overloaded • Whirring
That makes it a bimodal system: expensive marginal flight and efficient wing-powered diving.
Horned Screamer
Air Bubbles Underneath the Skin
Grazing marsh plants • Calling across water • Standing on floating mats
Slow, grazing and conservative throughout, this is a low-frequency system.
