Larva Perfect Paragraph

Submitted by sditelberg on Fri, 01/25/2019 - 15:41

Upon closer examination, the larva has approximately 13 small black dots along the sides of its body, each corresponding to one of its segments. The larva also has three larger black spots on its left side more dorsal and towards its posterior. The larva’s head is brown and moves in space around the container, possibly in an attempt to discern its surroundings. The tip of the head appears the darkest of the whole region and its purpose is unclear. The tail of the larva is the same beige color as the body, although there are two small black dots on the end. When the larva moves, the tail inches forwards first and the rest of the body subsequently moves forward to compensate, propelling the larva ahead in peristaltic motion. The larva moves relatively slow around the outside rim of the container but is not limited to this pace. At times, the larva sticks its tail into the air, but does not move it around as much as its head. Perhaps this is another strategy to sense its surroundings.

Observation of Larvae

Some form of larvae was provided for observation. The size was longer in length and wider in diameter then other provided larvae. It had a bilateral structure, with a body shape that the middle part of the body being wider the head and tail. It had a shape of an ellipse. The larvae had a segmented body with two red dots on each side and a light line crossing through the segment horizontally. The color of the body was creamy white, the head was dark red, and the very tip of the head and the tail was black. Counting the head as the first segment, the second, third and fourth segment had a larger red paired foot that kept on moving as it was trying to sense something on the wall. The larvae moved in a wave-like motion with the front part of the body first stretching out then the hind part of the body following it to bring back the length to normal. The back part of the body, the sixth and seventh segment had smaller paired feet compared to the frontal feet, which seemed to only function for walking. The fifth, ninth, and the tenth segment did not exhibit any feet. There was a long black line that ran through the top of the head to the tip of the tail and on the sixth segment, there was a black spot on the skin. For the behavior aspect, the larvae did not show curiosity to the food inside of the container. It only showed concern to the wall. It did not walk the middle of the container, but stayed on the outer side of it. The larvae also did not show any distraction when the lid of the container was hit few times to make sound, nor when the container was moved around. It kept on walking along the side. However, when the container was flipped, the larvae had a shock, in which it stopped moving for few seconds. After time, the larvae started to roll around to adjust its orientation, then started to move in the wave-like motion again.

Observations of Larvae

Submitted by sharrath on Fri, 01/25/2019 - 15:40
  • small creature; about 3 cm long
  • slow movement with limited motility
  • moving around the perimeter of the container
  • rod-shaped body with segements
  • no legs that are visible
  • posterier has 2 dark brown circular spots
  • cone shaped head

I observe a small creature, living that is; circuling the perimeter of the container in which it is held captive. The creature is a light brown color in the shape of a rod that is about 3 centimeters long. I can assume that the creature is a larvae and is quite confused being in such an environment. If I shake the larvae into the middle of the container; it slowly makes its way to the edge of the container once more.

 

Anatomy of the Worm's Legs

Submitted by kwarny on Fri, 01/25/2019 - 15:40

The legs of the worm are essential for movement, especially for survival. By close observation, the legs near the front of the body are slightly longer and pointed. Further towards the back of the body, the legs are shorter and more stubby. These differences may be a result of the development of the worm that is still in process. Moreover, the shape of the body follows a bilateral symmetry as one side resembles a lot like the other side. For example, on each side there are about eight brown spots with one spot on each segment piece of the body. Lastly, the worm moves in a wave-like movement. Scrunching specific parts of its body one at a time allows that part to be lifted and then shifted forward. The mechanism produces a cascade of motion within its segments in the body to encourage movement.

Week 1 Perfect Paragraph

Submitted by sfairfield on Fri, 01/25/2019 - 15:40

The organism has an elongated, beige body, which is approximately one inch in length and includes ten segments.The body displays bilateral symmetry, and is narrower at one end and wider at the other. It achieves movement by extending and contracting its body in a manner similar to a worm. The organism has black markings on its narrower, anterior end and two brown dots on its posterior end. There is also a long dark mark extending down the midline of the body. The exterior of the body reflects light and appears opaque. The organism generally moves in a circle around the outer perimeter of the plastic container, and occasionally rears its anterior end. It seems to struggle more to move over the wood chips than it does the plastic, and I observed it attempt to push wood chips out of its path.

 

Characterization of an Unknown Organism

Submitted by afeltrin on Fri, 01/25/2019 - 15:39

The organism's body moves in a clear tandem, often displaying repetitive motions as it moves. Both ends of the organism move; yet, they seem as if they are separately controlled. It seems as though each end has a mind of its own. It has many short legs and displays odd body movements at times. The organism’s body appears to exhibit bilateral symmetry. Often, it stops to ingest the food present. The body is segmented, similar to millipedes. The anterior end contains darker pigmentation. There are small, brown spots along both sides of the body. Short hairs are examined along the body. It moves solely around the perimeter of the container. Two short legs are present at the end of the body, appearing to expand and contract. The front six legs appear to point out, similar to true legs, whereas the ten back legs are flatter and more circular. It can rollover if stuck on its side or back. There are two segments between the front and back legs that do not contain legs.

Observing the Worm

Submitted by cslavin on Fri, 01/25/2019 - 15:39

The object in the container is a worm-like organism. It is small, no longer than a finger nail. The body is the narrowest at the head and continues to widen slightly all the way down the body. The organism has a darker head and appears to have an external, hard shell that is a yellowish and clear color. There appears to be a white, squishy tissue inside of that shell and two dots at the end of the body that look like eyes. It is legless and propels its body by elongating portions at the end of the body that travel up to the head. This motion is similar to a slinky. When the organism is flipped upside down it clings to the floor and does not fall unless the container is shaken. It is very active and has only taken one motionless break which lasted a couple minutes.

Organism observations week 1

Submitted by rdigregorio on Fri, 01/25/2019 - 15:39

Within the plastic container is a small organism that seems to move by muscle contractions. The muscle contractions move along the body laterally allowing it to inch around the container. The organism stays on the perimeter of the container and when put in the middle it inches back out to the edge. It is a tan color and seems to have a translucent outer layer if tissue. There are rings on the organism that go around the entire circumference of the body. They seem to be evenly spread out, and they form ridges because they protrude from the skin. Also there is something inside the body that goes from the tip of the head all the way to the tail. It looks as though it may be a neural cord of some kind or it could be a digestive tract. On the front of the body there is a black section at the very tip which may be the sensory system of the organism. There are two brown spots on the back of organism. From these observations lead me to believe it is a larvae of some kind.

Organism Draft

Submitted by cynthiaguzma on Fri, 01/25/2019 - 15:38

The organism appears to be about an inch in length and has small rings circling its body. These rings protrude from its body and seem to help it move. The width of the organism things out towards one end and gradually comes to a small black tip. This tip seems to help the organism sense its surrounding and move around by digging onto the surface and squirming forward. The other end of the organism is a lot thicker and cuts off leaving it looking as if someone cut off a chunk of its body. This section contains two red dots that frame the end. The overall color of the subject is a light tan and it has a translucent layer around it that is shiny. It also has an almost cloudy interior. The underside of the organism almost perfectly resembles the top.

Observations of Organism Perfect Paragraph

Submitted by ddoyleperkin on Fri, 01/25/2019 - 15:38

What appeared in my container was a seemingly simple, elongate insect in an early stage of its life cycle, perhaps its larval state. This organism was beige in color with a dark brown coloration at its head. This insect consisted of a head with a mouth and no eyes, a 3-4 cm long body separated into about 12 segments with 6 legs very proximal to its head, and a caudal end with what looked like two separate appendages sticking out at the end. This organism moves by first feeling its immediate surroundings with its true legs, then contracting, sending a wave from the caudal end of its body to the rostral end, grabbing the ground with pro-legs found near the middle and back of the ventral side of its body. Other notable visual characteristics include the dark coloration of the legs and the tiny dark spots that are present on either side of each segment of its body. There are no notable smells or sounds coming from the organism.

The way that the insect moves seems to be random. It grasps at surfaces, looking for obstacles until it decides to move forward. After shining a flashlight on it, I discovered an adverse reaction, so the organism prefers to be in the dark. It also has a hard time returning its legs to the ground once it has been flipped over.
