Frequency signatures: Parma Wallaby to Philippine Eagle
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 1,561–1,584.
Parma Wallaby
Edge-Grazing Dusk Retreat
Crepuscular • Edge-bound • Quiet
Because the animal runs a repeated short foraging cycle governed by light rather than by hunger, it is a mid-frequency system.
Patagonian Hog-nosed Skunk
Warning First, Spray Rationed
Rooting • Signalling • Withholding
That makes it a low-frequency system: slow durable groundwork protected by a signal that costs nothing to repeat.
Patagonian Mara
One Partner, Communal Crèche
Grazing • Guarding • Visiting
Continuous grazing with continuous watching makes this a mid-frequency system.
Patas Monkey
A Primate Built Like a Dog
Spread • Quiet • Scattered
That makes it a bimodal system: quiet dispersed foraging and a short explosive run.
Pea Aphid
Daughters Already Pregnant at Birth
Clonal • Viviparous • Telescoping
That makes it a phase-changing system: summer clonal multiplication and a seasonal sexual switch.
Peach-faced Lovebird
Daily Water Run, Borrowed Weaver Chamber
Flocking • Drinking • Seed-eating
That makes it a bimodal system: daily flock movement to feed and drink and sheltered pair nesting.
Peacock Butterfly
Opening Four Eyes and Hissing
Sitting closed with wings that look like dead leaf • Snapping them open to present four large eyespots • Rubbing the wing bases together to produce an audible hiss
Since disturbances recur unpredictably through the day, it operates as a mid-frequency system.
Peacock Fly
Wings Fanned Over the Back on Bark
Patrolling • Bark-bound • Sun-seeking
That makes it a bimodal system: steady bark patrol and short bouts of display.
Peacock Katydid
Dead-Leaf Wings Hiding Painted Eyes
Masquerading • Motionless • Night-feeding
That makes it a bimodal system: long masquerade and a brief startle.
Peacock Mantis Shrimp
A Spring-Loaded Club Behind the Latch
Burrowed • Scanning • Signalling
That makes it a bimodal system: long watchful sheltering and an extremely brief strike.
Peacock Spider
A Dance Sent Through the Leaf
Raising the fan • Waving the legs • Drumming the substrate
Fast, brief and short-horizon, this is a high-frequency system.
Peacock Tarantula
Iridescent Stand-off Display
Hidden • Still • Cryptic
Because its biology is built around a quiet, cryptic default with a distinct, high-intensity warning display when boundaries are crossed, the system is best understood as bimodal: a low-frequency concealment mode and a high-frequency threat-flare mode.
Peanut-headed Lanternfly
Decoy Headflare Display
Sudden • Flash • Misdirect
That makes it a high-frequency system built around brief startle pulses that create just enough confusion for escape.
Pearl Oysters
Nacre Over Whatever Gets In
Detecting material lodged between the mantle and the shell • Depositing successive layers of aragonite tablets and protein over it • Producing a smooth interior where an irritant would otherwise wound the mantle
Since deposition is continuous, it operates as a mid-frequency system.
Pelican Eel
Elastic Deep-Sea Gulp Net
Drifting • Coiled • Patient
This architecture creates two essential operating modes: long, low-expenditure waiting and rare, explosive expansion when opportunity and safety overlap, so the pelican eel is best described as a bimodal system with a low baseline and a high-frequency strike.
Pere David's Deer
A Species Rebuilt From Eighteen Animals
Wading • Splayed • Marsh-built
That makes it a bimodal system: a wetland-adapted animal and a population rebuilt through an extreme bottleneck.
Peregrine Falcon
Height Converted Into Speed
High • Circling • Positioned
That makes it a bimodal system: patient positioning and a single irreversible drop.
Perentie
A Forked Tongue Reading in Stereo
Flicking • Comparing • Following
That makes it a mid-frequency system: steady wide-ranging search over scattered food, guided by the difference between two sensors.
Periwinkle
A Door Pulled Shut
A horny plate on the foot that fits the shell aperture exactly • The animal withdrawing at low tide and pulling that plate closed behind it • A sealed chamber of seawater retained inside while the rock around it dries, heats and freezes
Because the cycle is tidal, it operates as a low-frequency system.
Persian Leopard
Rosettes That Close the Distance
Lying up • Watching • Approaching
Long motionless watching paying for a very short rush makes this a bimodal system, low-frequency on the ledge and high-frequency at the end.
Pesquet's Parrot
Bare-Headed Fig Specialist
Specialized • Distinct • Consistent
Because its appearance, anatomy and feeding are all tuned around a single, clear niche and signal, its operating rhythm is a steady, mid-frequency specialization rather than a slow reserve strategy or a rapid burst system.
Peters's Jumping Spider
A Retina That Moves
Two large forward-facing eyes with fixed lenses and a long tube behind each one, ending in a narrow retina • That retina moved by muscles, swept sideways and rotated behind the stationary lens rather than the whole eye turning • A high-resolution image built up by scanning a small acute region across the scene, so an animal a centimetre long resolves detail comparable to a much larger vertebrate
Because the scanning is continuous, it operates as a high-frequency system.
Philippine Crocodile
Small-Bodied Village Coexistence
Small • Freshwater • Tolerated
Because everything about the animal runs slowly, it is a low-frequency system.
Philippine Eagle
Paired Canopy Flush Hunting
Paired • Coordinated • Daily
Because hunting runs as a steady coordinated daily activity, it is a mid-frequency system.
