Grasshopper Dissection Lab

Grasshopper Dissection


Today we got the chance to dissect a Grasshopper! Although it was quite harder to dissect compared to the roundworms, it definitely was much more interesting!


This is a picture of our Grasshopper and as you can see, it does not have an ovipositor which means that it is a male.



Here are where the Head, Thorax, and Abdomen are located. And look, this grasshopper has 7 segments found on it's abdomen!



Here is a closer look at it's head all it's features.



This is a close-up of the grasshopper's legs. In this photo, only 2 legs are present, but all together the grasshopper has 6 legs.




Ever wonder what gives the grasshopper that extra "jump"? Well here is a closer look at it's wings, which make a huge impact when it comes to jumping.




Now that we have made observations on it's outward appearance, now we can start dissecting! Although it might not have all the special organs that humans have, grasshoppers do have unique organs. For example, their crop is like the storage place where food is stored before it becomes digest and it's gizzard are where enzymes are released to digest the food which then leads to the stomach.


Conlusion:


From doing this lab, one question that I still have about the grasshopper is how does the grasshopper transfer signals to it's body. In other words, I would still like to learn more about the Grasshopper's Brain/Nervous System.

  1. Thanks for the information! It is very helpful for me, I always don't understand the process perfectly and I search on internet to understand it beter. So for that I thank you for this post! But I think that is also important to have an good dissection kit to do it, so I recommend to have one. If you don't have one, you can buy one from here:
