Challenge Extension: Draw out taxonomic tree and showing your organism + the organisms being dissected by peers showing shared ancestry and shared traits.
How does an Octopus keep its shape?
An octopus doesn't have any bones, and relies solely on muscles to keep its shape. Usually, in order for muscles to be effective, they have to in some way be connected to a bone. Based off of the resources that I have used, researchers still aren’t sure how their muscular anatomy works.
Nutrition
Octopus feed mostly on crabs mollusks and many other small sea creatures
Digestion
Most of the digestion phases are based off of the diet of their prey.
Lifestages
1: Hatch from egg
2: Mate
3: Die
Ecosystem
Octopus are salt water creatures and tend to stay on the ocean floor. They are easily adaptable do to their ability to change color.

Dissection- Observed
I observed Susan Bakers Squid dissection, I didn't a lot that I didn't already know, but here are some things I observed:
- The ink sack was farther up the abdomen than I had anticipated.
- Compared to an octopus's neatly lined tentacles, squids tentacles look messy.
- The eye was a lot smaller than I expected
