Jellyfish Research Paper

The topic of my essay is going to about the mnemiopsis jellyfish and the harm the do to fish in the ocean specifically the black sea. The problem with them is that they eat the larva and eggs of the fish. In result, the people who fish in the black sea for a living are losing their product.

The cephalopodor octopus is a marine organism that inhabits many diverse regions of the ocean. Its food source consists of crabs, small fish, clams, mussels and other marine animals. The octopus is a predatory animal and has developed many skills to aid in its survival in the environment it has adapted to.

Lobsters are crustaceans that have been on earth for more that 480 million years and their average lifespan is 70 years. Their scientific name is Homarus americanus. The word lobster is an old english word that means spider. Lobsters are benthic creatures that are found in all of the world’s oceans, brackish water, and freshwater. A lobsters brain is located in its throat and its teeth are in its stomach. They have poor eyesight but an amazing sense of taste and smell. They mainly feed on fish, clams, sea stars, sea urchins, mussels and sometimes even other lobsters. Scientists have two theories on lobster cannibalism. The first theory is that rising water temperatures are causing lobsters to be more aggressive. The second theory is that lobsters

It’s a beautiful day at the beach, the sun is shining down on you as you float and drift on top of the waves. As you lay there without a care in the world, you are suddenly interrupted by a massive swarm of jellyfish; also known as a bloom. Not only does this send you into sudden terror, it also causes a much bigger threat to the ecosystem below you. The excessive growth of jellyfish swarm drastically lowers the population of fish eggs in the ecosystem. Because of this, fishermen lose millions of dollars. People in local communities are figuring out ways to solve this mass production.

Those tentacles have sucker-pads that help bring in the prey into the sharp beak the cuttlefish has. As the cuttlefish, being a carnivorous creature, it usually feeds on small crustaceans such as shrimp and crab. They also hunt on various types of fish along with others of its kind. During mating season male cuttlefish will change their body color to attracts a female cuttlefish. When the male cuttlefish is wooing a lady, he will often “cheat” by making female patterns on one side of the body while the other side the one facing the females shows off male patterns, this fools other males into thinking there just seeing a couple of females but that means more opportunity of the cheater cuttlefish to mate before they are discovered by other males. Female cuttlefish lay around 200 eggs and shortly die afterwards. In the cuttlefish they have this thing called the cuttlebone, but it is not actually a bone, but rather the internal shell of the cuttlefish, the cuttlebone is filled with gasses that help control buoyancy in the water. For years people have harvest and used the bones for many purposes. The usage of the cuttlebone is widely recognized as supplements and exercise toys for

They are predators; mostly carnivores that feed on fish, squid, molluscs, crustaceans and marine animals; some are herbivores that feed on plankton. They can also be filter-feeders or scavengers.

Jellyfish can be seen in freshwater and saltwater inhabiting everywhere it goes. Some may see jellyfish depicted in media such as the television show “SpongeBob SquarePants” as a fun recreational sport of catching Jellyfish in butterfly nets. Though most may recognize the creatures as your worse nightmare on a beach and avoiding getting stung by them. However, researchers and explorers have found effects that jellyfish have on impacting the ecosystem and life style of others. These findings have shown a divide between the benefits and negative outcomes they have.

In order for compass jelly fish to catch their prey they must catch it with their tentacles. They sting the prey and then use their tentacles/arms to pull it into its mouth. Its tentacles can be extended and also pulled back in. The compass jellyfish can give a painful sting and if you were to be stung, you should wash the wound in salt water and try to find vinegar. If you do not have vinegar, peeing on it will help the least. Vinegar takes the toxins of the sting out which will help release the pain the wound is causing. The jellyfish also disposes of its wastes throughout the same place the food goes in. When the jellyfish eats it must wait till it disposes of its wastes before it can catch its prey and eat

The upside down jellyfish appears very different than other jellies; they have a green/gray color to them opposed to the usual red, blue or violet. It works like a camouflage, as it makes them appear to be a sea anemone or a bush. They have radial symmetry, meaning that if cut into wedges, it would produce roughly the same result. The medusa has four branching tentacles used for feeding. It also has a depression on its bell that is used to attach to the ground since some of the jellyfish remain sedentary for most of its life. The jellyfish moves with the current of the water until it reaches a place where it can settle and attach and there it says for the remainder of its life. Other jellies will remain mobile in the medusa stage.

You may remember seeing the cute, seemingly harmless jellyfish in children TV shows when you were little. These innocent little creatures wouldn’t do a thing to harm anyone or anything. Right? While many people believe so, jellyfish are capable of electricity loss for days, and killing tons of people, due to an increase in their population. However, to stop these monsters in disguise, breeding another specific type of jellyfish, and taking away their resources will get rid of the overpopulation.

True starfish are classified in the Asteroidea, a group of echinoderms. True starfish have no sharp demarcation between arms and central body, and they move using tube feet rather than wriggling movements of the whole arms. True starfish and ophiuroids shared a common ancestor in the Ordovician. Most starfish are predators, feeding on sessile or slow-moving prey such as mollusks and barnacles. (example: crown-of-thorns starfish, Acanthaster specializes on corals, and may do considerable damage to coral reefs.) Many, but not all, starfish are able to turn a portion of their stomachs out through the mouth, and thus digest food outside of the body.

The Blue Glaucus mainly a on hydrozoans although there also known to be cannibalistic. One of the specialities of their diet is the Portugese Man-O-War, Physalia physalis (Linnaeus, 1758), they're known for their painful stings that they give when you touch their tentacles. The Blue Glaucus will eat the tentacles, both the fired and unfired stinging cells will pass these stings into special pouches in their cerata which they then use for defence.

The event that I attended was the McKinney Visiting Artist lecture featuring Mark Dion in Fine Arts room 102 on December 4, 2015. The title was “The Trouble with Jellyfish,” which made sense for about the first fifteen minutes because it was basically a lecture about jellyfish. How they live, thrive in conditions that would kill most sea life and their fossils. The point of this he said was to make us, the audience fall in love with jellyfish which then segue to the work he did in the Wunderkammen (Curiosity) Cabinets and other some of his other displays. Every display Dion talked about during his presentation involved animals or nature in way or another. I think the point of him talking about jellyfish in the beginning was not just not makes

The way that moon jellies move is the mechanism by which they move through the water and capture their prey. As the high drag moon jelly body plan moves through the water, it creates a current that delivers

In a land far away there was a kingdom, this kingdom was deemed the jelly kingdom. mainly because all of its inhabitants were made entirely up of a jelly like substance. Many citizens lived in this kingdom, mostly peasants and higher political figures but on top of them all lived the royal family. this family was made up of the queen, queen Alexandra and her son prince Pink. in recent years there had been a small battle between two kingdoms, the jelly kingdom and the fire kingdom. over time, the battle had evolved into a full-on war, it was known to all as the great rival war. in the midst of battle the late king, King Augustus had lost to a fire knight. There was a great mourning over his death, it was a sad day for all.
