What are the three types of fish?
Bony Fish
Cartilaginous Fish
Jawless Fish
What are three characteristics of Amphibians
Amphibians are the smallest group of Vertebrates.
Amphibians are cold blooded.
Amphibians begin life in the water breathing through gills. As they mature they grow lungs and legs so they can live on land.
Swim Bladder
located in the body cavity, it allows the fish to become buoyant or to maintain its depth.
Lamprey
Primitive fish. All existing fish descend from fish like this
Salamander
Spends most of its life on land.
How do Saltwater and Fresh Water fish get rid of excess water from their bodies?
Saltwater fish lose water through osmosis.
Freshwater fish lose water by releasing urine.
What are the three main groups of Amphibians?
Caecilians
Frogs/Toads
Newts/Salamanders
Gills
An organ used for breathing in fish.
The water enters a large surface area and passes oxygen into the blood and carbon dioxide out.
Sharks
Have a skeleton of cartilage,not bone.
Newts
Similar to a salamander, but its skin is rougher and not as slimy.
How do fish usually reproduce?
Female fish lay eggs and the male fertilizes them.
How can you tell the difference between Frogs and Toads?
Frogs have smoother skin and spend more time in the water than toads do.
Vertebrate
An animal that has a backbone or spinal column.
Coelacanth
Primitive bony fish.
Frog
Frogs drink water through their skin.
What is the lateral line and how do fish use it?
A Fluid filled tube That runs along the fishes body. A fish uses it to sense changes in water pressure.
How do some Amphibians, like the Poison Dart Frog, avoid predators?
By using camouflage or their poison glands.
Amphibian
Cold blooded animals that live on land or in the water; they have soft skin.
Perch
Modern bony fish that lives in freshwater.
Caecilians
Live in tropical regions, they hunt at night, and live in burrows underground
How does a fish breath in water?
A fish breathes by drawing water into its mouth and passing that water through its gills.
Describe the life cycle of a Frog
Egg
Tadpole - Tadpole matures, and develops legs
Young Frog transitions to land
Adult Frog matures
Tadpole
The larval stage in the life cycle of an amphibian.
Lungfish
Can survive by burying itself in the mud, staying motionless, and breathing air.
