Fish Dissection. Lab Report

Hello everybody. This time we are going to dissect a bony fish and discover external and internal structures of it. Enjoy!
Introduction: Fish and other vertebrates have much in common with humans. Many of the systems and organs are the same. Yet there are many unique differences in the organs and their functions in fish, and even between fish species. This lesson will be one for inquisitive exploration, and hands-on learning.
Purpose: to Identify the major internal and external organs of a fish. To compare and contrast human and fish internal organs, structures, and systems.
Hypothesis: Even though humans and fish do not look the same, we share similar organs and body parts.

  1. Identify external anatomical features of a fish.
    2. Identify a few major internal organs of a fish.

    3. Compare and contrast human and fish internal organs, structures, and systems.
  2. Result:
    1. Draw the picture of the fish with internal and external features.
    2. Fill the table where it is needed.
      Anal Fin used for balance and steering
      organ used to obtain oxygen from the water and rid carbon dioxide
      to sense low vibrations and water pressure
      Pectoral Fin
      Pelvic Fin
      “finger-like” organ that aids in digestion, using bile from the liver
      Swim bladder
Conclusion (answer these questions):
  1. What is the purpose of a swim bladder, and how does it work?
  2. What is the purpose of the Lateral Line?
  3. How does the Heart differ between humans and fish?
  4. From today’s lab name two organs fish have that humans do not.
