    The perch features are highlighted in the lab manual. Concentrating on structures that are listed above, what are features that help to distinguish bony fish from cartilaginous fish? Be sure to view slides of the different types of scales seen in bony fish.

    Your notes and drawings:

    Given the allometric (comparative) measurements you made last week on the shark and/or ratfish, let's make some similar measurements on the perch. Looking back on last week's notes, what are different proportions about cartilaginous fish vs. bony fish? Your instructor may want to graph class measurements.

    Total length (tip of mouth to tip of tail): __________

    Tail length (length of caudal fin): __________

    Pectoral fin length (point of attachment to tip): __________

    Pelvic fin length (point of attachment to tip): __________

    Point of attachment of pectoral fin to point of attachment of pelvic fin:

    (interfin length) __________

    Ratios:

    Tail length/total length: __________

    Pectoral fin length/pelvic fin length: __________

    Interfin length/total body length: __________

    What is the sex of your perch? __________

    Internal: pp. 291-295

    The perch internal features and approach to dissection are highlighted in the lab manual. Emphasis is on those structures listed in the word bank. Be sure to look again at the slide of fish gills. Note: your instructor may assign questions taken from the lab manual.
