Similarities Between Crayfish And The Frog

Crawfish are delicious crustaceans that closely resemble lobsters. Many people consider crawfish to be as delicious as lobsters, which is why these crustaceans are harvested all over the world. In the U.S., crawfish are closely associated with the haute cuisine and culture of Louisiana. In fact, crawfish are the official crustacean of the state. I normally prefer to harvest or purchase crawfish on the day I intend to cook them. However, many people prefer to purchase and eat them later but do not know how to keep crawfish alive in a sack or container for several days before finally preparing and eating them. Fortunately, I will provide you with some tips on how I keep my crawfish fresh and healthy

Complete the table below for the required systems listed. You are required to list four to six of the main organs of each body system, one or two sentences explaining the function of the system itself in your own words, and a short list of five to six major diseases that afflict each system.

All animals with limbs have a common design. If a batwing were to be formed from a person’s hand, make the fingers extremely long; a horse elongates the middle fingers and reduce and lose the outer ones; frogs elongate the bones of the leg and fuse several of them together. All in all, despite radical changes in what limbs do and what they look like, this underlying blueprint is always present.

First of all, the human body, crayfish, earthworm, and frog all have many similarities and differenced about how their digestive system works. They all eat their food through their mouths and the food then travels into the esophagus. The esophagus prepares the food for further digestion. The food in the esophagus then travels in the frog, crayfish, and human body’s stomach. The earthworm doesn’t have a stomach, but it has a crop that serves as a storage stomach. Once the food is in the stomach, something different happens for each organism. The food in the crayfish travels to the digestive gland which produces digestive substances and from which the absorption of nutrients occurs. The same thing occurs in a frog and the human body, but instead of a digestive gland it is moved into a small intestine. In the earthworm, the food goes from the stomach to the gizzard, which uses stones that the earthworm eats to grind the food completely. After it is moved into the digestive gland, small intestine, or gizzard, the food is mostly digested. The earthworm and human body’s food is now moved into the larger intestine, where it absorbs water and any remaining nutrients. The frogs food is stored in something like a large intestine, but it is called the gallbladder. The crayfish only has on intestine. After going through all this, the undigested material leaves through the anus, or for a frog, it is called the cloaca.

All organisms in the world have a range of systems and organs in their body. Some organisms may share similar body systems while others have absolutely nothing in common. Several of those organisms include humans, pigs, crayfish, and earthworms. From their mushy, gushy organs to their soft, gentle skin, you may think, “How are humans and pigs possibly alike? Or a crayfish and an earthworm?” In many ways they may not be, but in other ways, they are very much alike. The body systems that will be compared and contrasted of these organisms are the nervous, circulatory, reproductive, muscular, integumentary, digestive, excretory, and skeletal systems.

When society thinks about starfish, perch, chordate, and fetal pig they become extremely curious about how their bodies operate because of how they are made up. I will give a brief synopsis of all animals before going into major detail about them. According to the online website named dictionary.com, Starfish are any echinoderm of the class Asteroidea, having the body radially arranged, usually in the form of a star, with five or more rays or arms radiating from a central disk; asteroid (dictionary.com). It is known that a chordate is an animal belonging to the phylum Chordata, composed of true vertebrates and animals having a notochord (dictionary.com). According to research, a fetal pig is an animal in the phylum Chordata and class Mammalia (dictionary.com). A perch is known to be a certain kind of fish with very spiny fins (dictionary). Starfish, perch, chordate, and fetal pig are some very interesting animals that possess some exclusive qualities both similar and different.

When society thinks about crayfish and earthworms they become extremely curious about how their bodies operate because of how they are made up. I will give a brief synopsis of both animals before going into major detail about them. According to the online website named dictionary.com, it says that an earthworm is a burrowing annelid worm that lives in the soil. Earthworms play an important role in aerating and draining the soil and in burying organic matter (Dictionary). Crayfish are nocturnal freshwater crustacean that resembles a small lobster and inhabits in streams and rivers (Dictionary). Crayfish and earthworms are some very interesting animals that possess some exclusive qualities both similar and different.

This worm has other things it can eat as well. The one thing this worm loves to eat is the snail eggs it finds when it attaches itself to the bottom of the cabbage leaves and when it is searching for it's prey as well. Many scientists have said that the new guinea flatworm is one of the fifteen tenth largest dangerous and threatening invasion on the united states. They say it continues to grow even this year as well. It fact many people say that when it starts to develop the worms never stop growing and developing and continue to grow and grow and take over populations and specific areas in the united states. Many relationships with other species in the worm occur because the worm continues to invade state by state ,county by county or even area by area and it is causing problems everywhere. Another reason the specific species relationships happen is because the worms continue to have offspring and then they will continue to develop and develop. The next reason is the flatworm can carry a parasitic disease that infects rats and can be passed on to

In Joyas Voladoras, by Brian Doyle, Doyle compares the different types of hearts in various living organisms. He begins with the hummingbird, moving on to the blue whale, mammals and birds, reptiles and turtles, fish, insects and mollusks, worms, and unicellular bacteria. Although Doyle spends a great deal of the essay talking about the physical characteristics of the each organism’s heart, he actually conveys a deeper message. Doyle shows how all living things are related, both internally and externally.

Crayfish (Procambarus clarkii) are crustaceans that are similarly related to crabs, lobsters and shrimps. They live in partly salty water (brackish water), rivers, ponds and are considered omnivores because they feed on small fishes, plants, detritus, mollusk, and other small invertebrates. Crayfish have a hard-calcified exoskeleton which is typically made of structural polysaccharide called chitin. This calcified exoskeleton must shed for the crayfish to grow (Fitzgerald, 2006).

Each category of the book is filled with questions that range from why some organisms find copulation boring in their relationships to simple anatomical questions. Dr. Tatiana answers each of the proposed questions with comparisons to other organisms that experience the same situations. By doing this, she further provides readers with information on multiple organisms.

5). Although the student is being objective in the area of differences, the clear point is the cognizance in the fact that of both animals and human have goals; and that is to eat, sleep, and use the lavatory.

These two features earlier are examples that we can see with our naked eyes, but the DNA make up that we cannot see with our eyes alone are also laid out the same as well. In the evolutionary pathway, the genes that turn on and off for humans and fish are related through the instructions on how they function. All living things with limbs have in common the Sonic hedgehog gene (Shubin, p. 53). The Sonic hedgehog gene can control the development of the limbs in these creatures. To determine if the development of vertebrate animals can be interpreted in the same way, or have the same effect, the injection of vitamin A was used to inject into a shark, mice, and chicken embryos to see if the results were the same. The results turned out that the injection of vitamin A has indeed changed the development of limbs in these embryos. The effects cause the shark to have a mirror image of its fin, and the mice and chicken have duplication of bones in the limbs (Shubin, p.56-57). It becomes clear of what will happen if

The Pompeii worm is related to the Polychaete which are marine worms. This worm can handle temperatures up to 80℃ and can length up to 13cm. Their back is coated in a bacterial mat that reacts as an insulation system. Not only is their back coated with bacteria, but their whole body is covered in bristles in order for them to survive and move. The city Pompeii, was destroyed by the eruption of one of the most famous volcanos, they named the worm after the city because it's the most heat-tolerant organism. The next organism I observed was the Symphurus thermophilus that is known across several dispersed locations. This organism looks like rock or a nonliving object, however, it is actually a flatfish. Both eyes are found on the left side on the head of adults, their eyes are large and round. They also have 4-5 rows of teeth which are very sharp on the blind side while the eyed side has 1 row of teeth on the bottom and 2-3 rows on

The Rana pipien is a frog more commonly known by the name Northern Leopard Frog. They are characterized by dark spots on their dorsal side and dorsolateral folds and considered medium sized. This strong jumper is difficult to catch during the day. It emits startling “warning screams” when jumping into the water and when grabbed. The frog may also release urine to discourage potential predator and reduce weight for jumping. The Rana pipien eats a variety of invertebrates. During winter, they often spend it under under submerged logs or rocks in small streams or marshes where large numbers may congregate.
