Another fantastic frog fact for you!
news The Wood Frog (Rana Sylvatica) can survive being completely FROZEN for weeks at a time!
http://ukhairtransplantclinics.co.uk/?cir=where-can-you-buy-propecia-in-ireland The Wood Frog lives in the cold Arctic environment of Alaska so this is a very clever adaptation to have.
http://bothniafritid.se/?siresse=F%C3%B6r-Viagra-120-mg-p%C3%A5-n%C3%A4tet-visum&bf6=77 During the freezing winter, the tiny amphibians can survive for weeks with an incredible two-thirds of their body water completely frozen. Frozen frog popsicles!
http://restauracefantasy.cz/?kljaksade=brokeragecapital-com When their body temperature drops, they stop breathing and their hearts do not beat. In order to keep ice from freezing in their cells, they pull water away from their extremities and produce a type of antifreeze solution (known as cryoprotectants) that keeps them safe.
interracial dating in el paso tx In most animals, prolonged exposure to freezing temperatures causes cellular shrinkage — a process in which the formation of ice in the tissues pulls water from the body’s cells, essentially sucking them dry and eventually killing the cell. But in Wood Frogs, the cryoprotectants in their bodies, which includes glucose (blood sugar) and urea, lowers the freezing temperature of the animal’s tissues and reduces the amount of stress on the cells and tissues, allowing them to survive a deep freeze.

http://gryphus.com.br/?sokerpt=sinais-de-op%C3%A7%C3%B5es-binarias&e83=3b Darwin’s frog was named after Charles Darwin, who discovered this unique creature living in Argentina and Chile, while on his famous world voyage.
http://apisalud.es/?cours-de-dissertation-conomique Darwin’s Frog is a very cleverly adapted frog. It camouflages itself from predators by lying on the ground looking like a dead leaf (it has a pointy nose giving it a leaf shape). It can also turn on its back exposing the boldly patterned surface of its belly. The most amazing feature of this frog however, is that the tadpoles develop into frogs inside the male frog’s throat!
see here First, the female lays her eggs in the water. The male guards the eggs for 2-3 weeks but still, about half are eaten by insects and other predators. Any eggs that actually make it to the tadpole stage (usually about half) are swallowed by the male, who carries them around in his vocal pouch and protects them as they grow.

singel treff bergen But sometimes clever adaptations like this are not enough.
There are two species of tadpole-swallowing frogs. Rhinoderma darwinii is considered vulnerable and Rhinoderma rufum is considered critically endangered.
The vulnerable status of these frogs seems to be due to several reasons including deforestation, habitat loss, climate change and disease.
Well, technically speaking, the freakiest frog ever is NOT a frog.
It’s a TOAD.
A Surinam sea toad.
And it’s soooo FREAKY that it’s TOTALLY AWESOME!
The Surinam sea toad has adapted in the most amazing way. Only nature could have thought of this!
To keep their babies safe until they are big enough to survive on their own, Surinam sea toads implant eggs into the skin of the female’s back. The larvae develop into tadpoles which remain protected until they emerge as fully developed toads.
And totally GROSS!
Check out the video. Eugh !!!!!
Large flippered feet and greatly flattened bodies make these amphibians well suited to life in South America’s murky ponds and swamps, but habitat loss means this their future survival is currently regarded as threatened.
Are they adorable? Or horrifying?
One thing’s for sure. They are toad-ally FREAKY!
