4/22 - Dogfish Dissection

[Christopher Fisher]

Attached you will find the lab manual for our dissection of the dogfish.  There will be individual and group assignments for throughout dissection.  Please be careful while dissecting.  We are not butchers or hack jobs.  You will be expected to know the structure and function of each part of the shark.  

Your first assignment is to familiarize yourself with your shark, and memorize these terms and their definitions:

Cranial

Caudal

Dorsal 

Ventral

Medial

Distal

Lateral

[cameron.htx]

1. How is the shark’s nose different from our own? It's more pointy, and is underneath their face. Also the nostrils are more spread out.
2. Why are the Spiracles important? Provide oxygen to the blood directly to the eye and brain, through a seperate blood vessel which is reduced or absent in active
3. The mouth of the shark is part of which organ system(s)? Digestive and Repiratory system
4. What is the function of the Gill Slits? 5 vertical slits which allow water to exit
5. What does the Lateral Line do? Detects water movements
6. What two organ systems is the Cloaca a part of? Sex organs
7. Since the Clasper is only present on male dogfish sharks, what gender is your shark? Female
8. How many fins does a dogfish shark have? Seven
9. What’s another name for the Rostrum? Pointed snout
10. Where are the Dorsal Spines located? Cranial to each dorsal fin

[isabella.viterii]

[katrinaatiradoo]

1. How is the shark’s nose different from our own?

- they have different nostrils that breath in and out

2. Why are the Spiracles important?

- these openings allow water to pass through the gills even when the sharks mouth is closed

3. The mouth of the shark is part of which organ system(s)?

- digestive and respiratory

4. What is the function of the Gill Slits?

- 5 vertical slits which allow water to exit after passing over the gills

5. What does the Lateral Line do?

- a sensory organ that detects water movements

6. What two organ systems is the Cloaca a part of?

- reproductive and digestive

7. Since the Clasper is only present on male dogfish sharks, what gender is your shark?

- male

8. How many fins does a dogfish shark have?

- 5

9. What’s another name for the Rostrum?

- pointed snout

10. Where are the Dorsal Spines located?

- cranial to each dorsal fin

[neeeezyv]

1. Sharks don't use their nose to breathe & we do

2. Spiracles provide oxygenated blood directly to the eyes & brain through a separate blood vessel which isn't present in active sharks

3. The digestive & respiratory system

[kaelon23]

1. They don't use their nose to breathe

Nina, Isabella, Riley, Cameron.

1. The number of chambers the digestive system has.

2. The sharks have a more simplistic system and don't have veins that travel their blood. They use gills to get oxygen.

3. We layed the shark on it's back and pinned it down.

4. The chest was more tough to cut.

5. I found the fact that it was so similar to our own systems to be very interseting.
