Embryo: frog still in the egg.

Flying Frog Malayan Horned Frog The Malayan Horned frog has remarkable camouflage.
Does the Malayan Horned frog have horns? HORNS ? Wallace's Flying Frog Where it's name comes from?
It is very large and very colourful
Does it really fly? WEBBED FEET Australian Frogs Water Holding Frog There are 216 species of frogs in Australia, and aproximimately 200 of them are found only in Australia. As Australia has the 18th biggest number of threatened amphibians any loss of these spiecies in Australia means loss of species around the globe. Water Holding Frog I found the Water Holding frog very interesting because it was used by the Aboriginals. It carries water in pockets under it's skin. When the Aboriginals saw one, they lightly squeezed the frog so the water would come out. After a drink the frog is realeased unharmed.
As you can see the frog is mostly brown ,but, it can also be grey or green.
All of it's toes are webbed , and it spends dry times underground in a coccoon made of shed skin. African Frogs African Clawed Frog African Clawed Frog You can usually find an African Clawed Frog in Africa at the bottom of a lake. But people think it originated in South Africa. Either way you will always find them in a lake.
African Clawed frogs are usually greenish-grey but you may also see an African Clawed Frog in a different colour.
They have some stitch marks on the sides of their bodies that act as sense organs to find food in the water.
They only leave the water if they must migrate.They like slow water to fast rivers and can swim at astonoshing speeds and in every direction.
They can live from 5-15 years in the wild,but some can live up to 30 years. VIDEO TIME!!!!!!!!!!!!!!!!!! South American Frogs Golden Poison Dart Frog Strawberry Poison Dart Frog Golden Poison Dart Frog Phyllobates Terribilis can be called the golden frog, the golden poison frog ,golden poison arrow frog ,golden poison dart frog or golden dart frog. It usually lives in groups up to 6 frogs.
Either way this frog can kill 10,000 mice ,10-20 humans or 2 African bull elephants. Golden poison frog is not venomous but poisonous. Venomous animals get the venom through fangs, spikes etc. But poisonus animals have the poison everywhere.
Which means all you have to do is touch it... STRAWBERRY POISON DART FROG Strawberry poison dart frog is a small frog that lives in Central America.
These frogs are well known for different colour morphs you can find like: Blue jeans ,Bastimentos ,Chiriqui River and Man Creeks.
This species is different from other species because it takes care of it's young.
Females: feed the tadpoles their unfertilized eggs.
Males: defend and water the nests, but also carry the tadpoles on its back North American Frogs American Bullfrog CALL OF THE AMERICAN BULLFROG
http://www.torontozoo.com/adoptapond/audio/bullfrog.wav American Bullfrog The American Bullfrog is the largest frog in America
Lives in a pond with many plants
When first laid there could be more than 20,000 eggs in the clump!
Also later the eggs spread on the suface of the water.
3 years later all the tadpoles should be frogs.
Male bullfrogs reach mature life 3 years after changing into frogs although the females do it in 5 years or more.
Some bullfrogs live up to 9 years after transforming! Oregon spotted Frog Oregon spotted Frog (This information is from Earth Rangers website)
Oregon spotted frogs spend most of their lives in the water.
They have dark spots with light centres, that is why they are called spotted.
Their eyes are turned up so the frog can see surface of the water and the rest of its head and body is under water.
Around the world about 41% of the known 260 amphibian species are at risk of extinction.
Oregon spotted frogs can be hard to find because they are the most endangered amphibian in Canada.
Number of spotted frogs have dropped by 90% in the last 100 years. This frog is in real trouble. The four things are causing this:
Diseases Earth Rangers, in partnership with the Vancouver Aquarium, is working to protect Oregon spotted frogs.
Building a new breeding facility on the roof of the Vancouver Aquarium which will triple the number of tadpoles living there for release
Restoring wetland habitat in eastern Fraser Valley in Aldergrove Lake Regional Park where young Oregon spotted frogs bred at the Vancouver Aquarium will be released
Helping researchers at the Vancouver Aquarium breed tadpoles for release back into the wild in other suitable habitat areas Conclusion Red Bay Bruce Penninsula THE END !!!!!!!!!!!!! Now that we went aaaaaaaaaallllllllllllllll around the world filled with frogs I can finally do my conclusion.
I am going to show you pictures of me at Red Bay catching frogs, after we will do a Quiz, Questions and my Show and Tell: game and origami. QUIZ TIME !!!!!!!!!!!!!!!!!!!!!!!! QUESTIONS???? Frogs drink water. True or False?????????? How many continents did we visit??????????? What is a tympanum????????????????? RED BAY Frogs are my favorite animal because, last summer my sister and her friend found two frogs. That encouraged me to catch some frogs too.The frogs were awseome! Ever since frogs were my favorite animal.
