#lampreys — Public Fediverse posts

🐟⏳ #Coelacanths, #sturgeons, #lungfish, #lampreys, #hagfish, and #paddlefish all predate the #dinosaurs by tens to hundreds of millions of years.

Scientists sequenced their genomes, showing slow-evolving genes, ancient duplications, and clues to how our own ancestors moved onto land.

"Lampreys are boneless, jawless fish with #eel-like bodies that date back over 350 million years"

"Their feeding apparatus surprisingly resembles that of the pouched lampreys, foreshadows the ancestral flesh-eating habit of living lampreys.

Living lampreys are ancestrally flesh-eating and most probably originated in the Southern Hemisphere of the Late Cretaceous."

Sterilizing effects of cobalt-60 and cesium-137 radiation on male sea lampreys

By: L.H. Hanson, 1990

"Male spawning-run sea lampreys Petromyzon marinus were exposed to various doses of cobalt-60 or cesium-137 radiation in an attempt to sterilize them for use in a program for controlling sea lampreys through the release of sterile males. Males captured and irradiated during the early part of the upstream migration were not effectively sterilized at the doses tested. After irradiation, the sea lampreys were more susceptible to fungal infections by Saprolegnia sp., and many died without attempting to spawn. Males captured and irradiated during the middle and late parts of the spawning migration were effectively sterilized at a dose of 2,000 rads. However, some radiation-induced mortality was observed in males captured and irradiated during the middle part of the spawning migration. Radiation is not as effective as the chemosterilant bisazir for sterilizing male sea #lampreys."
