What eight characteristics are used to identify the family of a shark (e.g., the shape of the;body, etc.)?;2. What is the main structural characteristic that distinguishes shark number 12 from shark;1;number 7?;3. What is the main structural characteristic that distinguishes shark number 9 from shark;number 13?;4. What type of characteristics do you think would be used to distinguish between the sharks;into a specific genus?;5. What improvements could be made to this shark dichotomous key?;Exercise 2 Classification of a Fictional New Family;Questions;1. After arranging the fossil members of the Crawlas phylum, which of the examples is the;youngest species?;2. What two fossil members are the oldest specimens?;3. List two structural similarities that the fossil members share.;4. List two structural differences the fossil members share.;5. Use the dichotomous key to identify each living family Crawla in Figure by correct genus;and species based on structural similarities and differences. Record the genus and species;name in the table below.;Lab Report;Name;Section;Classification of Specimens from the Crawla Family;Crawla #;Species Name;Genus Name;1;2;3;4;5;6;7;8;9;10;11;12;13;14;15;6. Develop a hypothesis regarding the evolutionary links between the fossil and living;specimens based on the classification system used in this exercise.;3;7. Were some of the living Crawlas placed in the same species? If so, do you think the;similarities warranted classification in one species? Explain why or why not.;8. Were the characteristics of all of the living specimens able to fit in the key, or were there;some specimens that were difficult to place? Explain your answer.;9. Were the characteristics of all of the fossil specimens able to fit in the key, or were there;some specimens that were difficult to place? Explain your answer.;10. What is/are the main structural differences between living Crawlas number 1 and number 13?;11. Speculate and describe four structural characteristics that modern taxonomist would use to;classify real insects into their proper genus and species.
