Ms. Bridgeland 5th Grade
![Page 2: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/2.jpg)
Are Amphibians a CLASS or a PHYLYM?
![Page 3: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/3.jpg)
Amphibians: one of the 5 classes of Vertebrates
Reminder: What are the other 4 classes of Vertebrates?
![Page 4: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/4.jpg)
• Objective: Describe amphibian characteristics and examine how adult amphibians are adapted for life on land.
![Page 5: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/5.jpg)
Why do you think the word “Amphibian” means “double-life?”
![Page 6: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/6.jpg)
Amphibian: “Double – life” They begin their lives in water and spend their adulthood on land
To reproduce (have babies), they return to water
![Page 7: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/7.jpg)

What are the two major groups of amphibians?
![Page 9: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/9.jpg)
2 Major Groups of Amphibians1) Salamander
s:
2) Frogs/Toads:
![Page 10: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/10.jpg)
How can you tell the difference between salamanders and frogs/toads?
Salamanders have a tail even when they are adults
Frog/toads lose their tails before they become adults
![Page 11: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/11.jpg)
“What are the differences between FROGS and TOADS?”
![Page 12: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/12.jpg)
Frogs Toads
![Page 13: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/13.jpg)
FROGS: Need to live near water Have 2 bulging eyes Strong, long, webbed hind feet that are
adapted for leaping and swimming Strong and slimy skin (like very moist
environments) Will take long jumps Like to lay eggs in clusters Found on every continent except Antarctica More than 400 species Have a lot of PREDATORS
![Page 14: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/14.jpg)
TOADS Can live further away from water Lower, football-shaped eyes Stubby bodies with short hind legs (for walking
instead of hopping) Warty and drier skin Lay eggs in long chains Will run or take small hops Can be found worldwide except for Madagascar, the
polar regions, and Polynesia More than 300 species Do NOT have a lot of predators

Amphibian Reproduction
For all amphibians, Fertilized eggs develop in water
![Page 16: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/16.jpg)
What is unique/special about Amphibian eggs?
![Page 17: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/17.jpg)
What is special about amphibian eggs is that they have a protective jelly that coats the egg instead of a shell

Amphibian Eggs

How Amphibians Reproduce
There are 6 stages in the life cycle of an Amphibian: Here is what a frog looks like in some of the stages
![Page 20: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/20.jpg)
Stage 1: Adult frogs lay eggs in water
![Page 21: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/21.jpg)
Stage 2: Fertilized Eggs Male frogs fertilize the eggs, which lie in
water for a few days
![Page 22: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/22.jpg)
Stage 3: Larvae After a few days, larvae wriggle out of a
jelly that coats the egg and begin a free-swimming, fishlike life
Larvae of a frog or toad is called a _________
![Page 23: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/23.jpg)
As they grow, larvae undergo a ______________________?

Metamorphosis A process where an animal develops after
birth or hatching, involving a sudden change in the animal’s structure
![Page 25: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/25.jpg)
Stage 4: Larvae develops hind legs
![Page 26: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/26.jpg)

Stage 5: Front legs develop but frog still has tail
![Page 28: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/28.jpg)
Stage 6: Frog loses tail and becomes a mature adult
![Page 29: AMPHIBIANS Ms. Bridgeland 5 th Grade. Are Amphibians a CLASS or a PHYLYM?](https://reader030.fdocuments.in/reader030/viewer/2022032600/56649dbd5503460f94ab07b5/html5/thumbnails/29.jpg)
