Frequency signatures: Bluebottle Fly to Bornean Bristlehead
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 289–312.
Bluebottle Fly
Finding a Corpse by Smell
Detecting sulphur compounds from decomposition at long range • Flying upwind to the source • Laying within hours of death
Since the whole search-and-lay cycle runs within hours, it operates as a high-frequency system.
Blueface Angelfish
Eating What Is Chemically Defended
Grazing sponges and tunicates loaded with toxins and glass spicules • Processing those compounds rather than avoiding them • Feeding on a resource left almost untouched by other reef fish
Because feeding is steady, it operates as a low-frequency system.
Bluefin Tuna
Muscle-Warmed Ocean Crossing
Warm • Migratory • Never-still
Because the whole architecture is held at a high rate all the time, it is a high-frequency system.
Bluespine Unicornfish
Leathery Macroalgae Browsing
Ranging the reef • Cropping tough weed • Blades always out
Because the browsing is continuous and unhurried across a large area, it operates as a mid-frequency system.
Bluestreak Cleaner Wrasse
The Reef Service Station
Stationed • Repeat-trade • Trusted
That makes the wrasse a mid-frequency system: rhythmic, networked and built on repeated exchange rather than any single event.
Boa Constrictor
Tightening to the Heartbeat
Coiled • Still • Digesting
That makes it a bimodal system: near-total stillness and one intense, monitored, expensive event.
Boat-billed Heron
A Scoop Where Others Have a Spear
Waiting in mangrove shade • Scooping • Feeling with bristles
Slow and mostly stationary, this is a low-frequency system.
Bobbit Worm
Sediment Spring Trap
Buried • Coiled • Wait-then-strike
Because its whole biology is built around long periods of still concealment punctuated by very short, localized actions rather than ongoing activity or roaming bursts, the bobbit worm is best understood as a single-mode, low-frequency system.
Bobcat
Cover-Stalked Short Rush
Stalking • Broken-outlined • Patient
That makes it a bimodal system: a long patient approach and a very brief commitment.
Bocage's Wall Lizard
Patterned to the Stone Beneath
Dorsal patterning of green, brown and black reticulation matching lichen-mottled granite • Populations differing in ground colour and pattern density according to the rock they occupy • Individuals remaining on the substrate their pattern matches rather than moving between rock types
Because basking and darting alternate constantly, it operates as a mid-frequency system.
Boelen's Python
Basking Black Absorber
Dark • Warming • Infrequent
Since the system earns its heat passively and spends its energy only at rare intervals, it is a low-frequency system.
Bog Turtle
A Turtle Kept Alive by Spring Seepage
Hibernating • Buried • Spring-fed
The system switches between a dormant winter phase and a steady active season of basking, foraging and burrowing.
Bolas Spider
A Borrowed Scent on a Swinging Thread
Luring • Motionless • Chemical
That makes it a bimodal system: a long patient lure and a brief swing.
Bold Jumper
A Silk Line That Steers
Attaching a dragline before every leap • Paying it out during the jump and using tension to control pitch and rotation • Braking on it if the landing fails, and climbing back up the same line
Since jumps recur through the day, it operates as a high-frequency system.
Bombardier Beetle
The Pulsed Reaction Chamber
Foraging • Ordinary • Stored-apart
That makes it a bimodal system: a cheap ordinary baseline holding one violent, briefly available response.
Bongo
Vertical-Stripe Thicket Screen
Browsing • Screened • Nocturnal
Because the system converts steady quiet browsing inside cover into a living, it is a mid-frequency system.
Bonobo
Female Coalition Conflict Damping
Bonded • Defusing • Continuous
Because that regulation runs steadily through every day, it is a mid-frequency system.
Bontebok
White-Blaze Herd Legibility
Marked • Grouped • Open ground
Because grazing, watching and responding proceed as a steady daily rhythm, it is a mid-frequency system.
Boobook Owl
An Owl That Hunts by Eye
Perched • Watching • Calling
That makes it a bimodal system: a watchful perched baseline and short agile aerial captures.
Book Scorpion
Venom-Tipped Pincers in Hidden Crevices
Creeping • Seizing • Concealed
The system is bimodal: a LOW mode of concealed, patient hunting and a rare HIGH mode of hitchhiking dispersal.
Boomslang
Keyhole-Vision Branch Search
Searching • Sighted • Arboreal
Because the system runs on sustained searching with delayed chemical resolution, it is a mid-frequency system.
Bootlace Worm
Concealed Proboscis Launcher
Hidden • Poised • Reaching
That produces a mid-frequency pattern: a stable base of concealment punctuated by repeated, moderate, tool-based strikes whenever food and safety briefly overlap.
Bornean Bearded Pig
Tracking the Forest's Irregular Mast
Rooting • Foraging • Opportunistic
That makes it a bimodal system: steady opportunistic foraging with irregular bursts of movement and breeding.
Bornean Bristlehead
Isolated Canopy Relict
Rhythmic • Lineage-bound • Specialist
This produces a mid-frequency system: ongoing, rhythmic activity expressed through one enduring, singular lineage pattern rather than multiple modes or bursts.
