Compare two of the organisms that we have dissected Discuss at least 2 similarities and 3 differences

There are many organisms that we have dissected which are the clam, fish, crayfish, worm, grasshopper, frog and starfish. The ones that have the same habitat is the starfish and the clam the both live in clean water. The body systems that they have are respiratory, digestive, cardiovascular, and many others. Their oragns have to be close to the same because they live in water and their organs have to adapt to the water so its bulit to fit the water habitat. the digestive and respiratory system have to be alike in order to save in the water they have to have a digestive system that will be able to digestive the food and a respiratory system that will and allow the organism to breath. These to organisms are different in many ways one because of their exteior shell and the way its bulit to hide the organism from its enemies. Another way is that they live in different parts of the ocean one lives near the shore and one lives on the bottom of the ocean. The clam develops pearls which the starfish does not do at all so therefore the oragnisms are simliar and different.

What was most interesting about this week's dissections?

There were many dissections to choose from that we have done in biology. It was interestng to see the body part of many different animals. The worm and the crayfish were very interesting to see how each animal survive off the little organs that it has. The organs and body systems ared different and similar to others animals body systems. The most intersting dissection was the worm because i didnt get grossed out like i thought because it was clear to see the parts of the worms and to see its blood vessels and how the body of a worm works.

What surprised you from the worm's dissection?

The worm dissection was very interesting I have never seem anything like it before. It was a surprised to me because I am used to a human body structure. A human body structure it completely different from an animals body structure because it uses different organs and systems that keeps it alive. The worm dissection was surprising to me because i have never seen a structure so different. I never knew that a worm even had blood vessels i didn't know it had a heart i didn't know its body systems until i did the worm dissection.
