Frequency signatures: Sword-billed Hummingbird to Tentacled Snake
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 2.065–2.088.
Sword-billed Hummingbird
A Bill Too Long to Preen With
Hovering at deep flowers • Perching bill upward • Grooming with the feet
Fast and short-horizon, this is a high-frequency system.
Swordfish
Heated Eyes in Cold Water
Descending • Resolving • Slashing
Short committed attacks between long cruising makes this a single high-frequency system.
Tadpole Shrimp
Eggs That Wait Out Drought
Hatching within a day of a pool filling • Growing to full size in two or three weeks • Feeding on everything in the pool and laying before the water goes
Applying the structural test, these are two different states, making it a bimodal system.
Tailless Whip Scorpion
Antenniform Legs as a Map
Sweeping • Waiting • Grabbing
Almost nothing is spent between meals, which makes this a single low-frequency system.
Tailless Whip Spider
Two Legs Turned Into Antennae
Feeling • Mapping • Returning
That makes it a low-frequency system: slow, continuous and built on a remembered map rather than on a sense of direction.
Takahe
Tussock Base Extraction
Pulling • Chewing • All day
Because feeding is a fast steady repeated cycle, it is a mid-frequency system.
Takhi
Harem-Band Steppe Grazing
Banded • Grazing • Moving
Because the system runs on continuous grazing and coordinated movement, it is a mid-frequency system.
Takin
Oiled-Coat Altitude Shift
Heavy • Sealed • Seasonal
Because the system depends on structural investment and slow seasonal movement rather than on bursts, it is a low-frequency system.
Tamaraw
Dwarf Buffalo Grazing by Night on One Island
Grazing • Nocturnal • Solitary
A slow grazing routine at night makes it a SINGLE LOW system.
Tapanuli Orangutan
Upland Refuge Population Isolation
Upland • Isolated • Very few
Because everything runs at a very low rate, it is a low-frequency system.
Tarantula
Silk-Wired Listening Post
Waiting • Sensing • Conserving
The system is bimodal: long, sensitive stillness with rare, decisive attacks.
Tarantula Hawk Wasp
Paralysis Kept Fresh for Weeks
Provoking • Stinging • Hauling
One decisive act inside a short adult life makes this a single high-frequency system.
Tarpon
Surface Rolls for a Second Oxygen Supply
Cruising • Rolling • Air-gulping
It is bimodal: steady cruising punctuated by air breaths, and explosive feeding strikes.
Tasmanian Devil
Whole-Carcass Bone Mill
Nightly • Ranging • Processing
Because the system runs on sustained ranging and continuous processing capacity, it is a mid-frequency system.
Tasmanian Pademelon
Edge Grazing with Cover at Its Back
Concealed • Resting • Runway-bound
That makes it a bimodal system: daytime concealment in cover and dusk-to-night grazing at the edge.
Tasselled Wobbegong
Fringe That Erases the Edge
Flattened • Fringed • Motionless
A near-free hold and an instant engulfment make this a bimodal system.
Tawny Frogmouth
Holding the Pose of a Broken Branch
Frozen • Angled • Wooden
That makes it a bimodal system: total daytime stillness and moderate nocturnal activity.
Tawny Owl
Learned Territory Map
Resident • Memorised • Low-burn
That makes the tawny owl a low-frequency system: economical, resident and dependent on accumulated local knowledge rather than on searching.
Tayra
Green Plantains Left to Ripen
Ranging • Climbing • Anticipating
That makes it a high-frequency system: restless, exploratory and continuously active.
Tench
Surviving Where Oxygen Fails
Living in warm shallow water thick with vegetation • Tolerating dissolved oxygen levels that kill other fish • Burying into soft mud and remaining there when conditions become impossible
Since the cycle runs across a year, it operates as a low-frequency system.
Tenkile
Single-Massif Hunting Moratorium
Confined • Slow • Agreement-held
Because everything about the system runs at a very low rate, it is a low-frequency system.
Tent Tortoise
One Egg at a Time
Sheltering • Grazing briefly • Waiting out
Minimal expenditure and minimal output make this a single low-frequency system.
Tent-making Bat
Leaf Canopy Carpenter
Sheltered • Cautious • Site-faithful
Because their biology depends on both a conservative, shelter-centered resting state and a recurring cycle of movement and roost maintenance, the tent-making bat expresses a bimodal system with a low-frequency core and a mid-frequency working rhythm.
Tentacled Snake
Aiming Where the Fish Will Flee
Held in a J • Twitching the body • Striking before the fish moves
This is a low-frequency system.
