Arthropods

A dragonfly is a unique example of an arthropod. I find it interesting because of its transparent wings and also the fact that dragonflies are among the fastest flying insects in the world. The dragonfly has 6 legs(3 pairs,) constantly moults, and it also has an has a simple tube body form as well as bilateral symmetry. These are some characteristics of an arthropod that apply to the dragonfly :)

Squid yay

       
With this animal, I found the gills most interesting. When we put them in water, the gills opened up and fanned out to be a little bigger than normal. It showed how the gills might look like in real life when they are in use under the water. The whole squid was very interesting but the gills are my fave :P

Squids serve as biological research subjects. Some say that squids and molluscs never get cancer. This can help humans figure out how to become immune to cancer.
