Jellyfish Research Paper
There are more than 2,000 different types of jellyfish. Approximately 70 can hurt people with the box jellyfish being the most dangerous. Scientists believe that there could be as many as 300,000 different species of jellyfish yet to be discovered” (Lehnardt). The box jellyfish is one of the most well know jellyfish, it also happens to be the deadliest.
The most deadly jellyfish is named the Australian box jellyfish (as seen in the picture). “Box jellyfish, named for their body shape, have tentacles covered in biological booby traps known as nematocysts - tiny darts loaded with poison.While box jellyfish are found in warm coastal waters around the world, the lethal varieties are found primarily in the Indo-Pacific region and northern Australia. This includes the Australian box jellyfish (Chironex fleckeri), considered the most venomous marine animal. Chironex fleckeri is the largest of the box

“It has bell disks from 0.5 mm to a few mm in diameter. It reproduces asexually by splitting in half. Another contender for the smallest jellyfish is the extremely toxic Australian Irukandji, which is only the size of a fingernail” (Lehnardt). These jellyfish are only found in the deepest depths of the ocean and are very difficult to see without a magnifying glass, hand lens or, microscope. There is still one remaning question, what are jellyfish and what do they eat?
“Jellyfish are a type of plankton, meaning they are not strong swimmers and at the mercy of currents. When two currents meet, large concentrations of jellyfish, known as blooms, can form. When jellyfish blooms form, they can eat almost everything in the water. This can cause problems for commercial fisheries because the jellyfish will leaving nothing for the other fish in the same size category to eat” (jellywatch.org). Well that answers what jellyfish are but what do they eat and do they have

    Most starfish are carnivorous they prey on animals such as oysters, mussels, sea snails, and also clams. They find their prey with light sensing eyespots. These eyespots are located at the end of each of their arm. One is also located in the center of their bodies. It can only sense light and dark. They pry open the oysters with suction-cupped feet by wrapping their around the oyster shell and then pushes it stomach through its mouth and into the open shell. A starfish have two stomachs. They are call the cardiac stomach which is a sac-like organ located at the center of their bodies and then it the pyloric stomach where the digestion is completed. This adaptation allows starfish to eat animals larger than their…

    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…

    The vampire fish. That is what the Sea lamprey was nicknamed when discovered in 1835. First spotted in Lake Ontario, researchers were horrified to learn that the Sea lamprey feeds on blood. These parasitic fish latch on to their victims and siphon their blood and other body fluids, sucking them completely dry. What separates the Sea lamprey from other fish, other than their horrifying blood fetish, is their unique body structure. These fish do not have jaws or any other bone structure in their anatomy. Instead of the norm they possess a skeleton that is made out of cartilage. With a unique body set up, comes a unique mouth. It is described to be a large hole filled with sharp, pointy teeth. And this teeth frame a just as deadly tongue.…

    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 large. A terminal mouth allows this species to be a benthic and surface feeder. Their gill rakers are long and slender with space between them. This allows for particles in the water that flow into the mouth of the fish that they do not want to eat, to flush out. It indicates that the food of this fish is medium to large sized compared to their body. This correlates with an omnivorous diet and the ability to consume small and large prey. Daphnia and Cyclops are crustaceans often found in this species’ diet. Also, they help with mosquito control by feeding on mosquito larvae. The eyes of the Orangespotted Sunfish are corrected for spherical aberration, meaning they are a visual fish and need sight to find their prey. Since their prey is small fish and crustaceans, good eyesight is important to find them in the murky water that they live in. The Orangespotted Sunfish has adapted traits to better thrive in it’s…

    Jellyfish blooms have many negative effects on the ecology of the ocean and the economy of many places in the world. Seaside countries like Japan and Scotland have reported problems with finding jellyfish clogging water filters in their nuclear power plants. Compton's by Britannica states that a jellyfish's body has no skeleton and that more than nine tenths of it is jelly like. With that being said, one can see how these creatures may wind up obstructing seawater-fed pipes. Aside from the power plants, fishermen are affected as well, as the fish that they would normally catch can be devoured at a devastating rate by one of these blooms. These issues are a huge problem with long-lasting effects and can not be solved on their own without…

    Regeneration is the biological mechanism whereby organisms restore lost or damaged cells. This process can be used to replace organs, tissues and limbs on a small to large scale. Each type of regeneration requires different amounts of energy, resources and time. Orconectus rusticus (crayfish), compete for food, survival and mating. They have large claws that are vitally important in competition and survival. This species has developed the ability to regenerate these claws over time if they are lost or damaged. The motives and forms of regeneration in crayfish have evolved due to many factors. The effects that regeneration has are linked to the various needs that have evolved in the…

    Ahh the ctenophora, a wondrous and simple creature that symbolises the mystery of the vastly unexplored ocean, and exactly what beauty hides underneath. Today, with this compelling speech, I’m going to bring each and every one of you on a trip with me to the dark depths of the ocean, specifically 7000 metres deep, where we will find our star of the show. The comb jelly is an enigmatic creature which, in the vast tapestry of marine species, is really a testament to the diversity of life that lurks beneath the waves. First off, the comb jelly is not your typical jellyfish, as in fact, they are not one at all! Their name may suggest a relation, which is partially true as they are very distant relatives, but comb jellies are completely harmless to humans, and both belong to an entirely different phyla, jellyfish being Cnidaria and comb jellies being Ctenophora.…

    This shows that lionfish, with their fearless attitudes, will sting anything that comes too close. A single prick from a lionfish can cause hours of pain and even paralysis (Gupta 1). I myself have been stung by a lionfish on the finger, so I know to keep a close eye on them when I am snorkeling. The problem is that lionfish do an excellent job of blending in with the reef. Lionfish have golden brown and white stripes which help them camouflage with the reef, and their fins and tentacles are long and wavy, giving them the appearance of a piece of seaweed. This is why lionfish are not only dangerous to fish but also to humans.…

    The first kind of coral reef are fringing reefs, or shore reefs. These reefs grow directly off the shore. A shore reef is the most common kind of reef. Even though these reefs are grown near the shore, human impact can cause harm. These types of reefs can be found surrounding pacific islands. The second kind of reef that can be formed is a barrier reef; this reef is grown linear to the shore, but is usually separated by a lagoon. These types of reefs are less common than the others. An example of a barrier reef is The Great Barrier Reef, which is located off the coast of Australia. The third type of is known as atoll. This type of reef is circular and is often found above a huge lagoon in the deep ocean. These reefs are located in the IndoPacific region and a better example of one can be found in the French…

    There are fringing, barrier, and atoll. Fringing reefs are attached to margins of an island or continent and is rough. Fringing reefs grow in shallow water near the shore and prefer dry climates. Barrier reefs grow best where the land is sinking faster than the water.The third type of coral reef is the atoll. Atolls consist of a continuous or broken ring of coral reef surrounding a central lagoon. Atolls are unique because they reach to depths of thousands of meters to the ocean floor. The reefs cover only about 1% of the earth’s surface. Lastly, in my research I found out that Scientific reports show that there has been a rapid increase in the damage to reefs in the past 20 years, and scientists believe that in two more decades, the world’s reefs will decline by 30%. Over half the world’s reefs are in danger of human harm, and 27% are at high risk.…
