In the book The Sixth Extinction: An Unnatural History by Elizabeth Kolbert the opening chapter is on the high extinction rate among frogs of the world. The Panamanian Golden Frog, Atelopus zeteki, whose home is in Panama, Central America, is featured. That is because it is being tracked carefully by scientists at El Valle de Anton, lat/lon 8.60668, -80.1252, in an effort to discover what is killing the various frog species. The Golden frog was until recently considered a good luck symbol in Panama, but they are going toward extinction and that’s not good luck. Go to Save the frogs.com
My plan for saving these frogs and possibly many other frogs, and other animals as well, depends on their natural ability to be frozen and then, when thawed, to return to their normal life. I saw this demonstrated once where two small frogs were dropped into liquid nitrogen, where they instantly froze solid. Then one of them was retrieved from the flask and dropped onto a lab table where it shattered into pieces. The second frog was gently placed in the midst of his companion’s melting remains and allowed to thaw slowly. When that frog reached room temperature he hopped away and resumed normal frog activities.
If a frog were to be placed at The Earth Ark near the top of the Antarctica mountains where it is always below minus 40° C temperature, it may have survived in suspended animation for years. That could be very easily put to an empirical test; perhaps it already has. The ability to be revived from being frozen may vary among frog species, but it may also be available to other species. If some species could be saved in this way they could be stored and be brought back to life in the distant future. This is a technology that can become viable quickly when the various DNA factors become known and then using CRISPR gene manipulation to make the needed changes. When that becomes possible many species could be modified to become freezable and thus revivable when warmed to their normal operating temperature.
The freezing of frogs is a method for saving the frogs and probably some other species from extinction.
