Slide 1: 

Hey! Check our habitat!

Do you know me? : 

Do you know me? ..so let me introduce myself to you! I am Frogiee…(Frog), I am an Amphibian, I’m also called as Anura (Greek Word meaning tail-less) …Well my name is derived from old English, frogga. Cognate with Sanskrit, plava (derived from Proto-Indo-European praw = to jump

Do you know how am I Classified? : 

Do you know how am I Classified? Hey you know my elderly friends have long hind legs, a short body, webbed digits, protruding eyes and the absence of a tail! Huh…of course they are adults! You know, most frogs have a semi-aquatic lifestyle, but move easily on land by jumping or climbing.

Slide 4: 

Hey I have Vertebrates!

Hey what about my favourate food! U know it? : 

Hey what about my favourate food! U know it? My teacher says, “Frogs and toads mainly live on animals such as small insects. They are a very important part of the worlds eco-system. They are the vital link in the food change between insects and other predators”

HA…my teacher says something more! : 

HA…my teacher says something more! “Tadpoles mostly eat plants but are not solely vegetation feeders. Many are vegetarian in the early stages but become more carnivorous towards the end of this cycle. Bufo nebulifer tadpoles have been known to consume a full earthworm in about an hour.”

But my dad and mum prefer eating insects.. Yukk i hate it! : 

Hey thats me! But my dad and mum prefer eating insects.. Yukk i hate it!

Hey I’ll tell you a life cycle of a frog. : 

Hey I’ll tell you a life cycle of a frog. The Egg Frogs lay their eggs in water or wet places.  A floating clump of eggs is called frog spawn.     The large and slippery mass of eggs are too big to be eaten.  This is nature's way of protecting them.  But, the smaller clumps of eggs will be eaten by the creatures living near or in the pond. The egg begins as a single cell. Several thousand  are sometimes laid at once. It becomes surrounded by a jellylike covering, which protects the egg. The female may or may not stay with the eggs to take care of the young after she has laid them. The egg slowly develops. But, only a few develop into adults.  Ducks, fish, insects, and other water creatures eat the eggs.

What happens next? I’ll tell you. : 

What happens next? I’ll tell you. The Cell Splits The single cell in the egg eventually splits into many cells in the egg. The Embryo The mass of cells in the egg form an embryo. Organs and gills begin to form, and in the meantime, the embryo lives off its internal yolk. This supplies it with nutrients for 21 days. Then . . .

The Tadpole. : 

The Tadpole. later the embryo leaves its jelly shell, and attaches itself to a weed in the water. This quickly becomes a tadpole, a baby frog.   The tadpoles grow until they are big enough to break free into the water.  This can take from 3 days to 3 weeks.  They eat very small plants like algae. The tadpole has a long tail, and lives in the water. It is extremely vulnerable, and must rely on its camouflage to protect itself.

The tadpole begins to change : 

The tadpole begins to change After about five weeks, the tadpole begins to change. It starts to grow hind legs, which are soon followed with forelegs.   Behind their heads bulges appear where their front legs are growing. Their tails become smaller.  Lungs begin to develop, preparing the frog for its life on land.   Now and then, they wiggle to the surface to breathe in air.  The tail becomes larger and makes it now possible for the tadpole to swim around and catch food.  They eat plants and decaying animal matter.  Some tadpoles eat frogs eggs and other tadpoles.

Almost There . . . : 

Almost There . . . Over time, the tadpole becomes even more froglike.  They have shed their skin and lips. Its mouth widens, and it loses its horny jaws. The tail becomes much smaller, and the legs grow. The lungs are almost functioning at this point.

My life! : 

My life! I live my life, but I have to fight with some things! Phew..its real difficult..I’ll Explain you how. I have many enemies.  Foxes, bats,  rats, birds, fish, raccoons, turtles, snakes, and humans are a frog's enemy.  But human beings are the worst!  I and my friends destroy their homes and breeding places by replacing natural areas with cities, homes, and farms,  We also pollute and therefore poison the water in which frogs live. Whoa! I like it.. After all they are my enemies.

Look we have bulgy eyes! : 

Look we have bulgy eyes! Frogs have fairly good eyesight, which helps them in capturing food and avoiding any enemies.  A frog's eyes bulge out so he can see in almost any direction.

Slide 15: 

Not all species of frog protect themselves the same way.  Some frogs have poison glands in their skin.  The skin secretes the liquid and covers the body with the poison.  Some frogs use their colors to protect themselves. This warns the enemies that they will either taste bad or they may be poisonous.

Slide 16: 

Hey I wasn't boasting about myself!

Take a closer look at the eggs. :
