Observations: Rough Draft

Submitted by oringham on Fri, 01/26/2018 - 15:00

It is a small bean shape with a thin and long tail. It is soft and squishy to the touch. The object has a taupe color but its semitransparent on the main body. You can see that it is filled with organs and fluid of some sort. The tail is not transparent, and Is a darker brown. It seems to have a small opening at the end of the body opposite of the tail, leading me to believe that it is its mouth. Additionally, it has eight little nubby legs, and walks like a caterpillar. It is alive and has awakened. I don’t know what it is but it is not aesthetically pleasing and kind of creepy. It is trying to escape my petri dish. Originally it was covered in sawdust. I believe it is a red tailed maggot, hence the sawdust. It seems to like to crawl around the perimeter of the petri dish. To crawl, it pushes forward its head and then scrunches its tail towards the head. It is interesting to see its organs shift as he crawls around the dish. He appears to have tiny sensors by his mouth opening as well. Additionally, when he is touched, he does not struggle but rather freezes and acts as if he is dead. Once you leave him alone for a minute, he will continue to move around. I also believe if it is not the organs that I see inside him moving, it is the buts of sawdust he has eaten. He broke free of the petri dish and I had to corral him back in. He is 3 cm long including tail. His body length resting is about 1.25 cm long

Tan translucent skin

“tail” which is longer than its body

Has a mouth

Moves like a worm

Body moves from about half of an inch when contracted to about a full inch in length

Has some form of feet which have grip

Stops moving for about 30 seconds when touched

Tail acts as a sheath for a long black spine, which is uncovered on the end

Can flip itself over

Not sure if it can see, seems to move aimlessly around the dish. Doesn’t react to a pile of woodchips in front of it

Squishy body, seems to be no form of chitenous exoskeleton

Body is about 15 mm fully extended

~15 mm tail, always stays the same length

Locomotion seems to start from the bottom of the specimen, contracting before the rest of the body does, at which point the newly excess “skin” moves in front of the body.

White organs in the underbelly

Seems to use its “mouth” to move, using it as a grip point to pull on

White and brown organs through seen through the translucent skin on top

Tries to get out of petri dish by climbing walls, perpetually unsuccessful

Has small “hairs” on body

Where does it usually live?

What does it eat?

Kill it, cut it open

Observing Fly Larvae

Observing 1/26/18
• Somewhat transparent exterior with a yellow/ tan tint
• Short cylindrical body with long thin tail at end, tail is rigid, approximately the length of the body and a third, black tip that is not covered by transparent exterior
• Moves in one direction in fashion of inch worm, approximately seven sets of feet/ grips
• Can see the head (front) is a darker color, seems to have some type of opening that is exposed when elongated (possible mouth)
• There is also a darker section at the back that extends through the tail
• The middle of the specimen appears to be white, but it does not seem to one piece of material, but possibly separate strands (two lines that run along the back and a more serpentine pattern on the bottom)
• There are black specks covering this white portion of the body
• Constantly moving, often around the edges of the dish, going up sides when able to
• When it reaches up the side it seems to hesitate with head in air (possibly its major sensory location)
• Occasionally flips itself over, but has no trouble correcting itself
• Has remnants of previous space, shavings of some type, possibly normal habitat is underground or someplace where it can burrow
• Tail doesn’t seem to serve immediate purpose, possible stinger, stability support, slightly flexible, possible it helps move through habitat
• Started to learn sides of dish, almost escaped once and continuously tried the same thing, no longer went around the sides, but went straight to edge
• Is this its final state or this a pupal stage?
• What is its ideal habitat?
• What does it eat?
• Is it used to being in an environment with light?
• What is function of tail?
• Is it in the same family to an inch worm?

• Body is 14mm when resting (extended), constricts down to 11mm
• Tail is about 17mm, the black tip accounting for just under 1mm
• 21mm in total length
• Approximately 3mm in width

With initial observation of this organism, you can see that she has a tail that is larger than his main body, she has the movement style of a worm as oppose to a snake where she shrinks and extends forward. Similar characteristics as a worm, besides tail. Has little feet, do not help stick to a surface though. Semi- clear outer skin on both body and tail. Tail has an exposed black top (past the semi-clear outer coat), She has a mouth and she halts movement with sensation of predation (moving the container). When flipped upside down she wiggles her forward half to flip over. Interior front ¾ has a white color which could be an extra layer of skin which protects it internal organs and the lower ¼ has a darker color – could signify waste. Pokes something out of his mouth when she moves forward. Bilaterally symmetrical with pair organs – pairs of feets.


Bodily measurements: at rest, his main body is about 1.1 cm, his tail is about 1.6 cm, giving us a whole-body length of 2.7 cm. During locomotion, she extends her body, when it is extended the main body reaches about 1.4 cm in length with the tail the same length. This makes her max length around 3.0 cm. When she contracts her body, it is about 1 cm in length. Her main body has a width of about .2 cm and her tail has a width of about .05cm. With the change in body lengths between movement, and through visual calculations, she moves about .3 cm each time she extends forward and then contracts her body.




Organism Observation

Submitted by lgorman on Fri, 01/26/2018 - 14:58

The subject is a larval looking organism that is moving around. It was placed in the bowl along with some wood chips, which would lead me to believe that it prefers to be buried in the wood chip material. While it looks like it is trying to eat the woodchips sometimes, it is not trying to eat them. It has as pale green color with dark green lines on its main body segment that is about 1.25 cm long 0.25 cm thick, however that length varies as the organism changes shape when it moves. As it moves in a circular pattern around the bowl, I can see its white insides moving around as the pale green color comes from a somewhat translucent tissue layer on top of its inner organs. The entire body is covered by this translucent layer except for the tip of the tail. The dark lines that go throughout the main body segment looks as though they could be an organ system instead of just for decoration. The head of the organism has a lot of the dark coloration underneath the pale green layer of tissue. Perhaps the dark green is part of nervous system or circulatory system. It also has a dark green tail of some kind that is about 1.5 cm long and about 0.5 mm in thickness. It moves in a way that is very similar to a caterpillar. It seems to lead its motion with the opening of its mouth and then contracts its body and extends it. When looking at the underside of it, it has 8 pairs of “legs”. In addition to that it has a mouth on the bottom of its body at the front of the main body segment. When I touched the organism to move it to a place it could be measured, it had a very soft touch to it and felt very fragile. Whenever I touch the organism, it seems to freeze up for a couple seconds. Once I stop touching it, it resumes moving around the bowl.

One thing that I would want to know is what the creature would eat. If I put the organism on a leaf, would it eat the leaf? In addition to that, I am curious where it prefers to live. If I put it in an environment with dirt, would it try to burrow down to find safety? Or is it used to being up in a tree and munching on leaves? Ideally, I would try to let it grow up into its adult stage to figure out what this organism is the larval version of.

Observation of Mystery Larvae

Submitted by crmckenzie on Fri, 01/26/2018 - 14:57

This specimen is partially transparent and is long in shape, with a tail that is slightly longer than its body. The creature moves slowly in a slinking motion as if it is about to shed its skin but isn’t. Dark spots, what may be eyes, are centered at the front of the creature’s head. The tail is darker and there is a slight dark line throughout the creature’s body. The creature may not be able to see but can sense its surroundings in same way. It appears to be eating the wooden flakes and they are visible in its torso. The specimen keeps arching its anterior and continues to move in a slinking motion. Whenever the container is moved or the creature can sent a change in environment, the creature freezes and ceases to move for around thirty seconds. The creature prefers the edge of the container and mostly goes around and around and occasionally pokes its anterior upwards and touches the wall, perhaps attempting to escape. The creature moves like an inchworm. The specimen appears to be about 3.5 cm, with the torso being about 1.5 cm and the tail being 2 cm. I would like to know how this creature reacts in warmer and cooler temperatures, and I would also like to know how it would interact with others of its kind. Can it move faster when provoked? Why does it play dead when it senses change? Does this creature bite? Has it finished growing? How does it reproduce? Where are its pain receptors?

I see tree bark samplings that resemble wood chips, there also appears to be a creature moving in this tiny plate, possibly eating the wood chips. It is moving about in a circular direction because of the limited space provided. It has a long end or tail, needle thin-like, it reminds me of a worm or millipede or centipede but shorter in its body structure. It is trying to climb out the bowl but the surface is too slippery for the creature to grasp and have a firm holding of the surface to exit. At first, I thought this creature was a plant until it started to move and it frightened me. It has transparent skin and fur or a fuzzy like texture on its body, probably for sensing what is in its environment and also a possible use for transportation and movement. At this moment, I do not believe the creature or insect is eating the woodchips, I think it is more of a comfort factor for the type of environment it dwells in. This creature is clearly an invertebrate by the way it travels in the dish. There are also no visible facial features such as eyes, nose, ears etc. I believe most of its body is sensory embowed.
