Body Systems
Nervous System.
What is the system responsible for feeling?
a cold-blooded vertebrate animal of a class that comprises the frogs, toads, newts, and salamanders. They are distinguished by having an aquatic gill-breathing larval stage followed (typically) by a terrestrial lung-breathing adult stage.
What is an amphibian?
A vertebrate animal of a class that includes snakes, lizards, crocodiles, turtles, and tortoises. They are distinguished by having a dry scaly skin and typically laying soft-shelled eggs on land.
What is a reptile?
These are gill-bearing aquatic craniate animals that lack limbs with digits. They form a "sister" group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish also.
What is a fish?
Animal with a spine(or backbone).
What is a vertebrate?
The Circulatory System.
What is the system responsible for blood flow?
An amphibian that keeps a tail its entire life.
What is a tailed amphibian?
This group includes crocodiles and alligators.
What is Crocodilia?
A fish of a class distinguished by having a skeleton of cartilage rather than bone, including the sharks, rays, and chimeras.
What is a cartilaginous fish?
An animal that possesses the ability to generate its own body heat.
What is an endotherm?
The Respiratory System.
What is the system responsible for breathing?
Any of various tailless stout-bodied amphibians with long hind limbs for leaping; semiaquatic and terrestrial species.
What is a tailless amphibian?
This group includes lizards and snakes.
What is Squamata?
A superclass of jawless fish in the phylum Chordata, subphylum Vertebrata, consisting of both present and extinct species. The group is sister to all vertebrates with jaws, known as gnathostomes.
What is a jawless fish?
An animal that does not possess the ability to generate its own body heat.
What is an ectotherm?
Reproductive System.
What is the system responsible for reproducing?
Most amphibians breathe through lungs and their skin. Tadpoles and some aquatic amphibians have gills like fish that they use to breathe. There are a few amphibians that do not have lungs and only breathe through their skin.
How do amphibians breathe?
This group includes turtles and tortoises.
What is Testudines?
A fish of a large class distinguished by a skeleton of bone, and comprising the majority of modern fishes.
What is a bony fish?
This is basically made up of two types of tissues, these being bones and cartilage, cartilage being a firm tissue, but softer and more flexible than bone.
What is an endoskeleton made of?
Muscular System
What is the system responsible for everything movable?
When they hatch from their eggs, amphibians have gills so they can breathe in the water. They also have fins to help them swim, just like fish. Later, their bodies change, growing legs and lungs enabling them to live on the land.
How do amphibians grow?
Snakes and lizards belong to the same reptilian order but they have many differences. One difference that can be seen is that lizards have legs and snakes do not have legs. While lizards move on four limbs, a snake moves by undulating its body and also with the help of its ventral scales.
How can snakes and lizards be distinguished from each other?
There are jawless fishes, cartilaginous fishes, and bony fishes.
What are the three main groups of fish?
A spine or backbone.
