What´s Filter Feeding?
Filter feeding is the most common mechanism used by bivalves for feeding in the ocean (Dobson and Frid, 2008). Evolution occurred from Protobranchs, as they benefitted from food particles that filtered into their gills by chance, and adapted conveniently to become suspension feeders (Ruppert, 2004). This led to the advantageous change of bivalve gills to become lager and more equipped for filter feeding, as well as respiration. These are known as Lamellibranchs, although, there are some exceptions that have adapted to feed other ways. They are lacking in sensory mechanisms as they are no longer required and labial palps instead are utilised for feeding (Moore, 2006). Their gills have a cross-section that resembles a W-shape, that results in

    Week 7 Checkpoint: Physiology Assignment

    I chose to look up a diagram on a sea dwelling organism known as a Jellyfish. Jellyfish have many different forms and are often characterized in different groups. One jellyfish that stood out to me was the Aurelia or also known as the Moon Jellyfish, which is like the basic jellyfish that I’ve always seen in pictures and books growing up. Jellyfish are said to be very effective predators, as one point in the time they were considered to be at the top of food chain. Being effective predators makes them physically fit to be in any environment that they travel to. Even though most would say that jellyfish are horrible swimmers, they are actually in fact many are very strong precise swimmers. Jellyfish can swim horizontally and vertically by using contraction against their bell to expel jets of water to propel them. One drawback of them not being stronger swimmers like larger fish is that they often get caught in sea currents and get stuck in them as they go pass. The bell that propels them has a thick ring of strong muscle, called the coronal muscle. That muscle generates most of the power and energy used by a jellyfish. Now hanging from their subumbrellar is a projection called the manubrim which has the mouth its terminus. The mouth is often surrounded by oral arms normally just for but can sometimes be a multiple of four such as eight, depending on the type of species. Jellyfish don’t have a brain but they do bear a sophisticated computer which tends to all its needs and functions throughout the jellyfishes body. Though not as complex as a normal brain, it does suit the jellyfish well. Now on the edge of the underside of the jellyfish’s bell are its tentacles. The tentacles too can range in different numbers and sometimes some have thousands. These tentacles can be used to feed it, but also are use as it self defense mechanism to protect and also to hunt. The body and tentacles of a jellyfish can discharge…

    Essay On Daphnia Magna

    As expected, the control group had a feeding rate between that of the higher and lower light intensities. Buikema (1973) mentions that light intensities that exceed a certain threshold tend to suppress the filtering rate. We theorized that their feeding rate increased in the dark environment because it reflects their natural habitat. Populations of D. magna perform diel vertical migration, which means that they only spend the night in surface layers of the water and migrate downwards into the lower water layers during the day (Dodson, 1990; Haney, 1985). The ultimate cause for this is to protect themselves from predators. The proximal cause is the change in light intensity. D. magna present with photosensitive behaviour and they tend to move into areas of low light (Dodson, 1990). Young et al. (1984) report a decrease in the rate of limb beating when exposed to increased light intensity. The rate of limb beating directly affects the rate of filtration. If there is a decrease in the rate of limb beating then the feeding rate will also…

    Chemosensory organs in many crustaceans including Hyalella azteca allow them to locate food and mates while entirely avoiding predators. When detecting environmental changes such as the change in chemicals such as salinity, many amphipods have tiny hair-like organs containing sensory cells called sensilla (Hallberg, 2011). These chemosensory olfactory receptors are virtually found on many parts of the crustacean body including antennae, mouthparts and tips of the walking appendages (Hallberg, 2011).…

    The second pair of maxillae also helps to draw water over the gills. Of the eight pairs of appendages on the cephalothorax, the first three are maxillipeds, which hold food during eating. The chelipeds are the large claws that the crayfish uses for defense and to capture prey. Each of the four remaining segments contains a pair of walking legs. In the abdomen, the first five segments each have a pair of swimmerets, which create water currents and function in reproduction. The sixth segment contains a modified pair of uropods. In the middle of the uropods is a structure called the telson, which bears the anus. The uropod and telson together make up the tail fan. The crayfish moves backward by forcing water forward with its tail…

    The lionfish is a carnivore that feeds on other fish for food. It is red-and-white striped, with long pectoral fins. Lionfish normally have eighteen long needle-like dorsal fins. They use their long dorsal fins for defense against other fish or predators. Because the lionfish are carnivores, they rely on camouflage to seek and catch prey with ease (National Geographic). Lionfish also have a sting, that is extremely painful, that is used to catch their prey.…

    The Orangespotted Sunfish

    The compressifrom body shape is not as favorable for fitting into small spaces as the anguilliform, eel-like, style but with the small size of these fish and a larger amount and variety of refuge or cover found in rivers, they survive quite well. This compressiform body style allows this fish to make quick turns and short, fast bursts of speed with good maneuverability. The caudal fin is forked with a low aspect ratio meaning the tail is broad, the fish has good acceleration from the start, and the tail aids in hovering. A forked tail allows for good acceleration and maneuverability with a slight amount of drag. The dorsal fin has ten anterior spines that are directly connected to the rays of the posterior dorsal fin. Spines help protect this fish from predators and keep them balanced. The anal fin, outlined in black, also has three spines for extra protection. They have short and rounded pectoral fins which contribute to speed and allow the fish to fit into small crevasses. The primary swimming form of the Orangespotted Sunfish is labriform because they row their pectoral fins, an oscillatory fin motion. The mouth of these fish are terminal and moderately…

    Lamprey

    The Sea Lampreys (Petromyzon Marinus) are aquatic vertebrates that resemble eels, but unlike eels, they feed on large fish. They are also primitive jawless fish; they have a large sucking disk for a mouth and a well-developed sense of smell. Lampreys also do not contain any bones but only cartilage. Their bodies have smooth, scaleless skin, two dorsal fins, no lateral line, no vertebrates, and no paired fins. As larvae, a Lamprey is recorded to be about 6 inches long and an adult can be up to 18-24 inches in length. It is a dangerous fish because it is built to kill or prey on larger fish with poor defenses.…

    What Are Fed Diets

    Fed diets, what are they? They are diets that are made either by people or company to help people lose weight. There are many different kinds of fed diets out there today, some of them make sense and others not so much. While searching for food to critique for this pepper, I came across one that I thought was rather interesting. The paleo diet, it consists of all the food that men ate thousands of year’s age, so foods like lean meat, fruits/berries and vegetables non-starchy foods. You cannot eat other foods like beans, peanuts, green beans, lentils, etc., and grains are not included as well. All the food in the paleo diet is nutrient dense and fewer calories than the food that you cannot eat on the paleo diet. that is what prevent the excessive…

    All patient’s in the United States have all been equal to one right. The Patient’s Bill of Rights apply to this situation because an individual has the right to make their own decisions as long as they have the right mind and is fully competent. The Patient Bill of Rights is simply a statement that entitles the patient to medical care. A statement that articulates the rights in which the doctors and hospitals ought to provide patients, thereby providing information, offering fair treatment, and granting them autonomy over medical decisions. There are six values that are commonly applied to medical ethics (Showalter, 2010). The Bill of Rights include: the right to exercise the freedom of speech, to practice religion, be secure from unreasonable searches and seizures, bear arms in an organized militia, demand a jury trial, to be protected against self- incrimination and be accordance substantive and procedural due process of the law. This also applies to June because she has the right to choose her own path in life. In this case, June is suffering from a dangerous disease.…
