1. Observe the behavior of the live goldfish. Note the movement of the operculum. What is its function? Does a shark have an operculum?
2. Examine the model of the bony fish. Compare the fins, shape of the tail, scales and other external features with the shark.
How do the fins of fish contribute to the evolutionary story of animals evolving to life on land?
1. Observe and compare the features of the amphibian specimens.
2. The frog will be used to review vertebrate anatomy. Begin by examining the thin skin of the frog.
How does it compare to the skin of a reptile?
Would the frogs skin help protect it against water loss?
How is the frog able to supply its body tissues with enough oxygen even if there is some mixing of oxygenated deoxygenated blood?
Amphibian, literally means “living on both sides”. Explain why amphibians have that name.
What characteristics do reptiles have that make them more suited for terrestrial life than amphibians?
Why are birds thought of as flying…
