Book Synopsis Biology of the Sea Lamprey in Its Parasitic Phase by : Phillip Sheridan Parker
Book excerpt: Most of the experimental lampreys were mature and rip after 14 to 18 months of parasitic life. They exhibited signs of irreversible physical degeneration which precedes death. Three specimens were immature at 14, 18, and 26 months in aquariums, thus indicating that under certain conditions, lampreys may extend their parasitic phase.
