The image provided is a student worksheet focusing on the anatomy of a bony fish, specifically the Australian herring. The task involves labeling the parts of the fish and providing additional information such as the common name, scientific name, total length, weight, and sex of the fish.
Solution and Explanation:
#### 1.
Common Name and Scientific Name
-
Common Name: Australian Herring
-
Scientific Name: *Arripis georgiana*
#### 2.
Labeling the Fish Anatomy
The diagram already labels several parts of the fish. Here is a detailed explanation of each labeled part:
-
Nostril: Located near the head, used for sensing chemicals in water.
-
Brain: Controls the fish's nervous system and coordinates its actions.
-
Spinal Cord: Extends from the brain along the vertebral column, transmitting signals between the brain and body.
-
Vertebral Column (Spine): Provides structural support and protection for the spinal cord.
-
Muscle: Responsible for movement, particularly swimming.
-
Pyloric Caeca: Finger-like structures that increase the surface area of the intestine for better nutrient absorption.
-
Intestine: Part of the digestive system where nutrients are absorbed.
-
Vent: The opening through which waste is expelled from the body.
#### 3.
Additional Information
-
Total Length (mm): Measure the length of the fish from the tip of the snout to the end of the tail fin. This value should be filled in based on actual measurements.
-
Weight (g): Weigh the fish using a scale and record the weight in grams.
-
Male/Female: Determine the sex of the fish based on external or internal characteristics (e.g., presence of gonads).
#### 4.
Steps to Solve the Problem
-
Identify the Fish: The worksheet specifies that this is an Australian herring. Use the common and scientific names provided above.
-
Label the Diagram: Ensure all parts of the fish are correctly identified and labeled as shown in the diagram.
-
Measure and Weigh the Fish: Use appropriate tools to measure the total length and weigh the fish.
-
Determine Sex: Observe external features or dissect the fish to identify whether it is male or female.
#### Final Answer:
-
Common Name: Australian Herring
-
Scientific Name: *Arripis georgiana*
-
Total Length (mm): [Measure and fill in]
-
Weight (g): [Weigh and fill in]
-
Male/Female: [Determine and fill in]
Final Boxed Answer:
\[
\boxed{
\text{Common Name: Australian Herring} \\
\text{Scientific Name: Arripis georgiana} \\
\text{Total Length (mm): [Measure]} \\
\text{Weight (g): [Weigh]} \\
\text{Male/Female: [Determine]}
}
\]
