Paragonimus Westermani Compare And Contrast

Kang suspects that the worm bridges two temperature zones because the bacteria in its gut require warmth while its red plume harvests nutrients in the cooler water above” (nationalgeographic.com). Battling the harsh ecosystem, the giant tube worm’s plume helps it survive because the plume extends to the cool water to gather nutrients. It also has lots of blood vessels with large amounts of hemoglobin to help carry oxygen while living in extreme sulfide infested hydrothermal vents. In addition, the plume is retractable when threatened. Moreover, the bridging of the two temperature zones helps by supplying nutrients in the cooler water, while providing a heated home for the bacteria thus helping the giant tube worm’s symbiotic relationship. ­­­­­­­­The giant tube worm’s second adaptation is the combination of fatty acids in their lipid membranes and proton pumping mechanism. Extreme Marine reports, “In response to the immense pressure and low temperature of the deep ocean, tubeworms are able to increase the relative amount of rigid, double bonded unsaturated fatty acids in their lipid membranes. This prevents the membranes from packing densely together and ultimately solidifying (Cossins and Bowler, 1990). R.pachyptila also maintains a

Earthworm: In our dissection of the earth worm we found they belong to a group of animals called annelids. Its body is segmented into several parts, except for the head and tail regions. Its diet is of decomposed plants and other small particles in the

When the infective larvae on the pasture are eaten by the sheep they develop in the 4th stage larvae and become adults. This stage is called the host stage as they need to live inside a host (the sheep) or the worms will die. They live inside the sheep’s abomasum during which they lay eggs and will spend the rest of their lives and the whole cycle repeats itself

They are hairless and have seven short lines running down their back diagonally. They have a very long spine, or horn, at the end of their body. Because of this, they are part of the hornworm caterpillar group. Once the caterpillar is mature, the horn will have be gone and replaced by an eyespot. August and September is the usually time to spot a caterpillar of this species.

The mealworm is the larva of the mealworm beetle which is a specie of darkling beetle (Animals.mom.me, 2016). The darkling beetle has a metamorphic life cycle that begins with an egg hatching into a small mealworm over a four week period (Sandhyarani, 2016). The second life stage of a darkling beetle is the larva stage where the egg will hatch into a small brown mealworm that eats and grows for about eight to ten weeks till its next stage as a darkling beetle pupa (Sandhyarani, 2016). The larva stage of a darkling beetle is the stage in which the mealworms will be investigated. The mealworm will then enter the pupa stage during one of its shell sheds causing the mealworm to

The purpose of this assignment is to learn, observe and experience the biology of the Tobacco Hornworm through the different stages of its lifecycle, along with describing the processes which occur through each development stage. When I picked up my hornworm, I received three eggs in the tubular container. During my examination, the hornworms lived in two environments. They first lived in the small, tubular container they arrived in until they outgrew it. I then placed them in a large plastic container for the remainder of their lifecycle.

(Wormer). The eggs are dull white and 2.86 by 1.89 inches to 3.43 by 2.34

In order to reduce mortality rate and increase efficiency two methods were found in the life cycles of trematodes. The upward incorporation has a new definitive host from a high level of the food web and this host preys on the old definitive host (become intermediate) and are then combined together as one which reduces reproduction. The downward incorporation has a new intermediate host combined to a lower level of the food web and therefore, reduces mortality and makes it easier to go to the original host. Having multiple host is usually facultative

After looking at many physical pictures and pictures of their skull, paranthropus boisei do have resemblance of human characteristics.

The Nightcrawler worm is, like other species of worms, a hermaphrodite. Although the worm contains the sexual organs of both the genders, they still need to mate to reproduce. The two worms lie alongside each other and transfer sperm to the both of them. Each worm will lay capsules to be used as a cocoon for the egg. When the capsules break fully formed tiny worms will emerge. It is said that they prefer to mate during the spring and fall time. It takes a year for the tiny worms to fully grow, and it is also said worms live for 3-8 years, although that isn’t

An incision was made below the clitellum at around segment 40. The worm was cut on one side of the dorsal blood vessel, starting at the clitellum down to the anus with small scissors. A thin, shiny cuticle began to peel from the worm’s skin. A few times, the intestine was slightly cut and runny, dark brown soil began to seep out. After this, the worm’s clitellum (segments 30 to 38) was cut through to the mouth (segement 1) The worm’s skin was pinned down to the tray,

Limulis Polyhemus is the scientific name of the commonly known horseshoe crab. It is one of only four living members of Xiphosura. Being a common inhabitant of shallow waters and soft bottoms such as the beach, it can be found plowing on surface of the sand feeding on invertebrates that are collected from the sediment. This dioecious – dark brow organism is considered to be one of the largest chelicerates, that could reach a maximum length of 60cm. One character that differentiates Limulus from other arthropods, are the absence of antennae.

Have complete digestive system. It has mouth at the tip of a proboscis, followed by a pharynx, an esophagus, a stomach. Intestine and an anus.

The amazing thing about this parasite is its bizarre life cycle. It begins its life as a male and matures in the gills. Once developed, it matures into a female and only the female latches onto the tongue. Males

Considering this the Hornworm was kept under artificial light throughout the night and by a window through the day. The temperature was around 60-62 degrees Fahrenheit, which is typically too cold for the Hornworm. With that in consideration, we assumed the hornworm may possibly take more time to transition instars. The food source for the Tobacco Hornworm was what was provided which was a mixture of water, agar, and wheat germ.
