Historical Context
The species was eliminated from Miller Lake by poisoning in 1958, while records from the wider regional system demonstrate that the lake name is not the whole species distribution. Historical loss at one locality should not automatically be described as extinction of the entire species.
Larvae and Adults
Larvae occupy fine organic sediment, while adults feed parasitically on small fish. The adult feeding period is relatively short compared with the larval stage. Small adult size therefore does not mean this is a nonparasitic brook lamprey.
Spawning and Length
Adults construct small gravel-and-sand spawning depressions and die after reproduction. Spawning has been observed in both lake and stream settings. The maximum reference is 14.5 centimeters total length, and an individual record should preserve life stage and locality alongside the measurement.
Separate Local Loss from Species Extinction
A historical disappearance from Miller Lake does not describe every population. Keep the exact locality and date with that history.
