  1. Amphibian ADAPTATIONS Ms. Bridgeland 5th Grade

  2. Once an amphibian is an adult and lives on land, it needs new adaptations to survive on land

  3. Amphibians: ADAPTATIONS • What is an adaptation? • Once amphibians are adults, what new adaptations do they need to live on land?

  4. Adaptation: Breathing • While amphibians are larvae, (example tadpoles), how do they breathe?

  5. Once, they are on land, how do they breathe? • Amphibians must get oxygen from the AIR instead of the water once they are on land • During metamorphoses, amphibians lose their gills and develop LUNGS. • What two gases are exchanged through the lungs? • OXYGEN and CARBON DIOXIDE

  6. Adaptation: Movement • Some frogs have sticky pads on their toes to climb trees • Others have webbed feet for swimming • Being vertebrates, amphibians have strong skeletons to support their body against the pull of gravity and help with movement

  7. Adaptation: Getting Food • Tadpoles are HERBIVORES (only eat plants) • Adult salamanders, frogs, and toads are CARNIVORES • Frogs and toads WAIT for their prey and use long tongues to catch prey • Salamanders AMBUSH their prey(chase after their prey)using long tongues

  8. Adaptation: Defense • How Do Amphibians defend themselves?

  9. Talk with a partner and see if you can come up with 4 adaptations that a frog has to defend itself

  10. Defense: Frogs • Speed – frogs can leap up to 30 times their body length to get away from predators • Camouflage – hiding under rocks and leaves • Bright colors –warn predators that the frogs are poisonous • “Playing Dead”-staying very still so that predators think that they are dead

  11. Example of a Frog Camouflaging

  12. Example of a Poisonous Frog that uses bright colors to fend off predators

  13. Remember that toads cannot move as quickly as frogs. What are some adaptations that toads use to defend themselves against predators?(See if you can come up with 5)

  14. Defense: Toads • Poisonous Glands (sometimes) • Camouflage • Puffing Up (making themselves look too big for predators) • Playing Dead • Rolling Away –looks like a rolling stone

  15. Puffing Up to look too large to eat

  16. Toad “playing dead”

  17. What are three ways that salamanders defend themselves?Hint: think about a body part that salamanders have that frogs and toads do NOT have

  18. Defense: Salamanders • Autotomy: a self-amputation where a salamander or lizard loses its tail in self-defense • Poisonous Glands: many salamanders have poisonous glands on their neck • Poisonous Skin: brightly colored salamanders have poisonous skin
