This organism is approximately 0.75 inches in length during its resting position. It has ten segments, the inner eight are yellow/tan in color, and the outer two segments are dark brown. The organism resembles a grub, or a slug. It appears to have about 14 limbs, and two more limb-like projections that come from its tail end. This organism is a symmetrical invertebrate, that crawls around its environment similar to a caterpillar or an inch worm.
- This organism is small, about 1 inch long.
- It is round, shaped like a caterpillar.
- It appears to be limbless.
- It has 8 or 9 segments along its trunks.
- It is light yellow/tan colored in the center.
- It is dark brown on its two ends.
- Does this organism have the ability to see?
After rolling the organism over to see its bottom side:
- This organism has very short limbs.
-It slowly crawls, sensing its environment with its brown colored head.
-It moves around like a caterpillar/inch worm
-It is lifting its head up to try to get out of the cap.
- As time goes by the organism moves more and more.
I named this organism Oliver stione. Oliver Stone is a film writer who wrote the crtiticaly acclaimed movie Scarface. This is a writing class hence the name.
Oliver is a 23 mm bilateral symmetrical organism; he is divided between 10 segments wihout counting the head and the back end. He moves around the cup with the help of its multiple legs. The body movement of this organism start from the back end to teh front of its head, it ay fees as if one can see Oliver's internal organs while he moves. The middle part of hi sbody is bigger than its extremeties this might be due to eh fact that he realitively bigger than the neighboring organsims. He has tried to escape multiple times from the cup and is unbale to do so becasue his feets cannot grasp the materials that the cup is made of. When trying to climb, he elevates his head and climb but fall backwards. The organism rarely move backwards but when he does, the motion is the reverse of the upfront motion. Teh body movement goes front the head to the back end. The backwards movement are not as long as the upfront movement. They are more like 3 quick steps. Oliver passed most of its time moving along the edges of the cup in a circular fashion.
Observations: From my observations, the first thing that came to mind was that it looked like a yellow caterpillar. It has approximately 14 or 16 small feet and depending on the location of the feet, there could be different functions to the organism. The organism's head was a different color than the rest of the body. On it's head there were more hairs than on the rest of its body. It is quite active and moves in a myriad of directions (stretches, bends, rolls over, contracts) which leads me to assume at this point and time, it is quite young and has not yet reached adulthood. The organism is fragmented both vertically and horizontally. The organism's movement was peculiar in that it moved from its hindquarters in a wave-like motion to the front and forward. I found it interesting that it was interested in the wood chips.

There is an unknown organism in a plastic cup. This organism has a segmented body that is bilaterally symmetrical. It has sets of legs, three in the front and four in the back. The organism hardly stands up on his front legs, but it stands on the rear legs frequently. When this organism moves it has a wave like pattern that starts towards the tail end and moves to the head end. The organism typically moves around the edge of the cup it is in. The organism is about 24 millimeters in length and 4 millimeters wide. The widest part of the organism is its center.
The organism I am observing in class is a worm-like creature. For the sake of this entry, I will label the organism as a worm. I am observing the worm for fifteen minutes. The first observation I am making about the work is that it is about 2.3 centimeters long. I am utilizing a ruler to make that measurement. Secondly, I am focusing on the appearance of the worm. The organism appears to have a beige and a somewhat light brown body color. In addition, the head of the worm is a dark brown color, and its body is divided into ten different segments. The worm-like creature is bilaterally symmetrical. Thirdly, I observed the movement of the organism; it initially puts all of its force towards the back of its body and then thrusts itself forward. The movement is wave-like. The worm focuses its movement on the edge of the cup and never moves to the middle. Furthermore, the organism utilizes six legs in the front and eight legs in the back to move.
As you observe the worm-like organism, you can see the variations in the pigmentation. In addition to the difference in pigment in the head and body, the skin has and overall dry quality to it. The center of the organism is more lightly colored and in turn, you are able to see the insides of the worm. During movement, you can observe the independent movement of the external skin and the internal muscles and organs. You can see the delay of movement of the internal environment compared to the external. As you look closer you can see that there is a vein running along the length of the back. This vein allows you to more closely see the bilateral symmetry of the organism, this is also shown when you see that each of the segments are idntical on both sides. Also, running across the length of the body, one can observe small hairs. The hairs are more concentrated around the ead and are most likely used to sense what is in the surrounding area.
More information can be learned about the worm specimen being observed with the help of tools and experiments involving modifying the worm's environment. First, a sample of the specimen's DNA could be taken and analyzed to discover more about what species it belongs to. From this information, more can be learned about organisms the specimen is related to and any additional information that is already known about the species. It would also be informative to place the specimen with others of the same species and observe the behavior of each while in a group setting. Another helpful experiment, would be to keep the worm alive with others over a couple generations and are observe the life cycle of the species. Overall, there are many questions left unanswered by observation alone.
The initial question I had during this class excerise was "what the hell is this?" An initial observation I had for the organism that was presented in front of me was that it definitely resembled a worm. The most striking feature of this worm-like creature was it's long beige segmented body consisting of a dark brown and black head at it's front. Other noticeable features of the worm consisted of its legs and movement. The worm appears to have three pairs of small legs at the front of it's body, and through further observation it can be determined that they act as "feelers" that guide and lead the worm. The rear end of the worm also consists of different sets of legs, but they appear to have far less movement and appear to be stubbier than its frontal legs. The worm also has a specific type of movement, similar to an inch worm, in which the motion of it's body begins at its rear and moves, in a wave-like motion, along to the front of it's body. This wave-like motion is the reason why I had affectionally named this worm, Wave McDaniel.
Irwin is a worm like organism that has an off yellow segmented body which is composed of 12 segments including head and tail like structures. Irwin is approximately 2 cm long and 0.5 cm wide at its widest point and has a bilaterally symmetrical body. The head of the organism is an orange-brown structure and is composed of two semispherical eye like structures as well as a darker orange-red mouth structure. Additionally, the head area transitions into the body of the organism with the first body segment partially covered in the orange substance that compose the head.
