Description of motor behaviors and sequence of pulse intervals
| . | Description . | |
|---|---|---|
| Motor behavior | ||
| Flee | An arching of the body and avoidance of a potential attack | |
| Follow | The act of swimming closely behind a fish around and through objects in the tank | |
| Head-to-tail circling | Male and female follow each other in tight circular motion with the head of each sex near the other's caudal fin | |
| Hover | Stationary position with fins moving to stabilize position | |
| Lunge | A fish swims rapidly, directly and deliberately at an opponent head first that causes the receiver to arch in an escape response | |
| No activity | Laying on ventral side with no fin movement | |
| Probing | Stationary or back-and-forth movement of body around an object leading with head or tail | |
| Swim | Broad category where there is forward movement not directed at other fish | |
| Spawning | Rapid undulation of body in vent-to-vent coupling position | |
| SPIs | ||
| Creak | Total duration of 2000–3000 ms and characterized by a cessation prior to slow discharges (100–300 ms) followed by a burst at about 50 ms and a subsequent cessation | |
| Gradual increase | A fast burst followed by an increase of interval length to 60–100 ms over a period of 2000–6000 ms | |
| Fast burst | Series of pulses with intervals of 10–30 ms lasting no longer than 1000 ms | |
| Long cessation | No EODs for longer than 1000 ms | |
| Medium burst | Series of pulses with intervals of 30–70 ms lasting no longer than 1000 ms | |
| Random | No discernable SPI pattern | |
| Rasp | Burst of 4–10 pulses with 10–20 ms intervals followed by longer intervals of 25–50 ms | |
| Rasp matching | Although not an SPI by one individual, it is an electrical duet between the sexes during courtship. Male rasps or medium bursts would be followed by female fast bursts or vice versa. Varying duration of event and number of rasps, medium bursts and fast bursts produced | |
| Regularization | Sustained EOD intervals (±10 ms) for longer than one second | |
| Scallop | Sudden burst of 8–12 pulses of 10–20 ms from resting intervals(100–300 ms) and back | |
| Short cessation | No EOD activity for 200–1000 ms. Shorter cessations included in this category when a clear stop and start of two SPI patterns is evident | |
| Slow burst | Series of pulses with intervals of 70–100 ms lasting no longer than 1000 ms | |
| SPI, sequence of pulse interval. | ||
| EOD, electric organ discharge. | ||
