movement and anatomy of fish, the gap between the surface and the sea floor could be speedily lessening. For years humans have marveled at the speed and grace of most marine life. The lack of drag, the force propulsion, and the ability to live at such impossible depths have been forever the envy of submarines and sea explorers. After years of observing these incredible functions, researchers are finally beginning to mimic and apply these characteristics to marine technology. These robo-fish hold the
Behind the second dorsal fin, are between 7-9 finlets, which aid the fish in “reducing turbulence and maintaining directional control when swimming at high speeds” (Gardieff, Susie). On the underlying side of the Tuna, the anal fin is present and it is in about the same location below the second dorsal fin, and following the anal fin is another 7-8 finlets. The fish has short pectoral fins consisting of between 26-27 rays. The fish also have a single row of teeth, shaped conically (cone shaped) (FLMNH)
When I imagine a fish that resembles a sea monster, I immediately picture a sea lamprey (Petromyzon marinus). These fish are jawless and can grow up to 80 cm as an adult. An adult lamprey’s mouth has teeth arranged in circular rows like something from a nightmare. When it comes time to feed, sea lamprey latch on to a host and drill a hole to obtain nutrient-rich blood. If that weren’t enough, they only have two dorsal fins and one caudal fin and lack pelvic and pectoral fins, which gives them an
The dwarf seahorse’s scientific name is hippocampus zosterae. The dwarf seahorse faces an uncertain future. It is threatened by habitat loss (Biological Diversity). It is the slowest fish on earth with a speed of five feet per hour (Guinness World Records). It spends most of its time using its tail to cling to seagrass and catch tiny plankton. They are found mostly found in the Florida Keys, Bahamas, Bermuda, and the Gulf of Mexico (Monterey Bay Aquarium). The female generally has reproductive maturity
identify potential causes for particular quality problems. They are often called fishbone diagrams because they look like the bones of a fish. A general cause-and-effect diagram is shown in Figure . The “head” of the fish is the quality problem, such as damaged zippers on a garment or broken valves on a tire. The diagram is drawn so that the “spine” of the fish connects the “head” to the possible cause of the problem. These causes could be related to the machines, workers, measurement, suppliers
barbels that stick out from their chins like whiskers. These barbels help the catfish find crabs, fish and shrimp in the muddy bays where they live. The dorsal and pectoral fins each are supported by a sharp, slime-covered barbed spine. The catfish is covered in a mildly toxic slime, that causes severe pain, and swelling, should the catfish cut you. The dorsal spine normally is held erect when the fish is excited and a tennis shoe or even a leather-soled shoe offers little protection. Adults may reach
The structure and function of the different fins of the Rainbow Trout, Oncorhynchus mykiss The Rainbow trout, belonging to the family Salmonidae, Class Actinopterygii (ray finned fish), inhabitscold streams, rivers and lakes in North America. Ones living in lakes have silver scales apart from those on their back which are dark green. They are covered in dark spots that usually go no further than the lateral line. The lateral line is a line of sense organs found on the side of the Rainbow trout.
breathe underwater, what if it was a possibility? The human anatomy would need to change in order to support the same anatomy that allows fish to swim and breathe underwater. All fish have gills. Gills are tissues which consisting of filaments. These filaments have capillaries that allow the exchange of oxygen and carbon dioxide, acids, and ammonia. The gills are located on either side of the pharynx. “How Fish Breathe Underwater” states, A fish breathes by taking water in through the mouth and forcing
use their intellect.” (Surat al-Baqara: 164) Fish are one of Allah’s mighty creations on this world. Fish are just another common type of organism which exists on this Earth. Fish are everywhere; from the aquarium in an office to the Atlantic Ocean and from the book “Fish Tales” to the notorious movie “Finding Nemo.” The term
The yellow stingray is a member of the Urolophidae, or round ray family. The scientific name for a yellow stingray is Urobatus jamaicensis, which originates from the Greek words “oura” meaning tail and “batis” meaning a ray. It is most commonly called the yellow stingray, but can also be known as round stingray, yellow spotted stingray, and the maid stingray. (Piercy, 2009) Like other rays of the Urolophidae family, the yellow stingray has an almost round body, or disc body. It has a circular shaped
What is the largest fish in the world? The answer would be the Rhincodon typus, or commonly known as, the whale shark. The whale shark is vey unique because unlike normal sharks, the whale shark is a filter feeder and so, does not have use of its teeth. The whale shark is also about the size of a bus. However, like many animals in the world today, they are considered vulnerable according to the IUCN. They are seen often in the tropical areas, but many behavior and movement mechanism of the whale
Anatomy of a False Confession Depending on what study is read, the incidence of false confession is less than 35 per year, up to 600 per year. That is a significant variance in range, but no matter how it is evaluated or what numbers are calculated, the fact remains that false confessions are a reality. Why would an innocent person confess to a crime that she did not commit? Are personal factors, such as age, education, and mental state, the primary reason for a suspect to confess? Are law enforcement
The purpose of this study is to examine the cost effectiveness of mid level providers, such as physician assistants, compared to physicians. In order to thoroughly evaluate the difference in cost one must look at more than one aspect of the physician assistant versus the classic physician. From a purely economic standpoint one needs to address the cost of education, differences in the way patients are treated based on the kind of medicine practiced and the cost of employment between physician assistants
Friends: our novel kinship during medical school. It is said that friendship is a single soul dwelling in two bodies. Well, everybody must have friends don’t they? One is in great affliction if one thinks that one can live by his own. Most of us medical students are studying abroad or quite far from our family. Some of us even went as far as crossing continents and studying in Europe or the Middle East. One cannot help to stop and pause to argue that the next closest to us after our family would
Grey’s Anatomy Have you ever thought about how many people watch television every day? “Close to 20 million people tune in every week to the show Grey’s Anatomy” (askville.amazon.com). Some of the viewers watch the show every week and are dedicated fans. Others just watch when they can catch it, but even when they don’t watch it every time, it still has an effect. Viewers who are not regular watchers tend to look at more of the medical information. They stop on the channel because they like medical
The early hominins of Africa were similar to other hominins in gross anatomical features, however, there were differences between the early hominins of Africa and other hominins, such as those found in Asia and other parts of the world as discovered in fossil remains. Not only were there some differences in the anatomical structures, there were also evidentiary differences in their culture and environmental factors in their lives, especially as the species evolved. Below, I will compare some of
Anatomy & Physiology of the case scenario Having described the scenario, this essay will now focus on the anatomy and physiology during Laura’s third stage. After the delivery of her baby, Laura’s uterus continued to contract and retract due to the effect of oxytocin on the myometrium. Herman (2000) and Herman et al. (2002) describe the placental separation in three stages; latent, contraction/detachment and expulsion. During the latent phase Laura’s myometrium begun to contract and retract. During
Motor movement development has been a topic of controversy for the last century. The feud began in 1906 when Sir Charles Sherrington published The Integrative Action of the Nervous System. The work summarizes over two decades of research, revealing many fundamentals of neural science for the very first time (Burke, 2007). He was not only the first to suggest that the nervous system was a complex network of separate neurons, coining the term ‘synapse’, but he also was the first to discuss reflex
The objectives of this lab were fulfilled. During the dissection, diagrams of the rat were conducted from several different perspectives including both the dorsal and ventral views. Throughout the dissection, the prior knowledge that was theoretically learned in class, assisted in allowing the group to have a more complete and thorough understanding of the different organs, and parts that were present in the rat. This helped reveal the several different similarities and differences in the circulatory
I like doing a lot of things but four things stand out to me the most as defining factors of my personality. I have always wanted to help people through service. Service is important because it allows me to connect with others on a personal level as I help them. Hiking is also important to me because I can go out in the wilderness and hike for five to ten miles without seeing any man made structures. This allows me to connect with nature and deepen my understanding of natural settings. Guitar is
