Unformatted text preview: Name Student # UNIVERSITY OF TORONTO Faculty of Arts and Science December 2013 Examinations EEB 382H1 F — Diversity of Fishes Final Examination Prof. Hernan Lopez-Femandez Duration — 2 hours; No examination aids are allowed. There are 31 questions in total. All questions require short answers, and often one word is sufficient. Be clear (explain your answers), but be brief and answer Within the space provided on the exam. Longer answers than necessary will not be considered better answers. The exam is 7 pages in total. This examination [72 marks total, with 10% pure lab content] is worth 32% of your total course mark. 1) Name three factors that affect species discovery (3 points) 2) In a tragic turn of events the Royal Ontario Museum burns to the ground, destroying the holotype of Krobz’a petitella. In a later revision of the genus Krobz‘a, what kind of type specimen would you designate to represent this species? (1 point) 3) As a journal editor, you receive a manuscript submission describing two new species. The etymology of their names is given as follows: 0 Guianacara albus — from the Latin albus meaning white, to be regarded as an adjective in feminine form - Guianacara mclennani — for Prof. Deborah McLennan, to be regarded as a noun in apposition What would the names be once you have corrected all errors? (1 point) 4) What is the function of the enormous amounts of slime produced by hagfishes?

(1 point) 6) The origin of jaws in vertebrates has been called “the greatest of all advances in vertebrate history”. Why? Answer by explaining two advantages gained by jawed fishes over agnathans. (3 points) 7) What is the main defining anatomical character of fishes in the Acanthomorphata? (1 point) 8) What is the main anatomical character that defines Ovalentariae? (1 Point) 9) Why are cichlids considered a model of vertebrate evolutionary biology and adaptive radiation? (2 points) 10) What does it mean that lungfish “estivate”? (1 point) 11) On the next page are a set of illustrations of extant or fossil fish. Using your knowledge of fish morphology from class and your evolution lab, which of the following groups is this fish most closely related (1 each = 4 points) a) Agnatha, b) Chondrichthyes c) Sarcopterygii, d) Basal Ray-Pinned Fish (Chondrostei, Cladistia), e) Holostei, t) Basal Teleosts (Anguilliforms + Osteoglossiformes), g) Ostariophysi, h) Acanthomorphata (Acanthopterygii + Paracanthopterygii) 2/7 Name C *dn = dentary, pm = premaxilla Student # /7 Name Student # 12) Why do we say that, generally, fish do not have to overcome gravity? (1 point) 13) How are frictional and pressure drag produced? a) Frictional (2 points) b) Pressure (2 points) 14) What three key components of body shape make a fish streamlined? (3 points) 15) Describe the two main types of movement involved in fish propulsion: undulation and oscillation. c) Undulation (2 point) (1) Oscillation (2 point) 16) The diagram below shows the caudal region of a Bigeye Tuna. What are four adaptations for high critical swimming speed illustrated here? (1 point each = 4 points) 4/7 Name Student # 17) When comparing a carangiform and a thunniform swimmer, which one has a larger portion of the body performing undulatory movement?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
