Many people view jellyfish as small monstrosities, due to their uncommon feature in this common world. Despite the perceptions people have of jellyfish, they are extremely important in marine life. Jellyfish are also food for many marine animals making life in the ocean a continuous cycle. Jellyfish play an important part globally and in order to make sense of jellyfish, it is important to know what jellyfish are, how they live, how to treat their stings, and the benefits of the species. With this knowledge, it is clear that jellyfish are not our enemy.
Jellyfish are free-swimming marine animals consisting of a gelatinous umbrella-shaped bell and trailing tentacles from the Animalia kingdom and belong to the class of Scyphozoa with many other jelly-like creatures (Dickerson). These fascinating creatures have no bones, no head, no gills, no brain and no organs that help them to breathe or excrete waste (Dickerson). Some jellyfish are transparent, so you can see right through them (Taylor 1: 11). The free-swimmers belonging to the class Scyphozoa, are one of the oldest creatures alive today on Earth. They consist of ninety-five percent water, three percent salt and two percent protein. No brain, no digestive system, no respiratory system, and no bones. Is it not interesting that they have survived for so long without a single help? The scientific name for jellyfish is Medusozoa (2014, April 15). Multiple names have been given to the free-swimming specie such as Jellies, Sea Jellies, and Jellyfish.
Jellies have flexible limbs that outline their mouth called tentacles. All jellyfish have tentacles that vary in length and amount, and consist of cnidoblasts which possess stinging threads called nematocysts.(“Jellyfish” Think ). Tentacl...

A defining feature of the lionfish which everyone sees are the “18 venomous spines on its dorsal fin and its pelvic and anal fins, which are used for defense” as described in FACE OFF WITH THE ENEMY: LIONFISH by Special To The Citizen. Which is a neurotoxin that results in intense pain and swelling of one’s body. Fernando Simal, a marine hunter at STINAPA National Marine Park, found out the potency of their venom after his first hunt when being stung by the lionfish he caug...

Next we can remove the tentacles still attached to the stung area with tweezers, shaving cream and a blade, or something straight edged to scrape off the tentacles. We then rinse the are again with vinegar or seawater. We can then treat the area with calming jel, medical attention is then advised to be seeked to further treat the sting.
So photophores is a light some deep sea fish have which helps in complete darkness. Photophores help fish get away from pretadors. So the fish "turn on" its light one place then "turn off " the light and shine in another place confusing the predator giving it time to escape.So many deep see fish have small eyes or are blind because there is no light down there. These fish usally, you could say sense when things are around them so they really dont need their eyes. Gelatinous skeleton is a skeleton that is very soft and mushy but still holds a type of shape. These fish have gelatinous skeletons becuase of the high pressure underwater if a human were to go down there they would die from the pressure. That is only some adaptions deep sea fish have and deeep sea fish are not the only fish with adaptations in their

CORAL REEFS Almost every one of us have heard and most of you have seen the Coral reefs but did you know what actually these are: As a mariner its important to know about the marine life, that was one reason I have chosen this topic for my today’s short presentation. GM, my scheme of presentation will be flashed. DEFINATION OF CORAL REEF DIFFERENCE BETWEEN CORAL AND CORAL POLYP WHERE WE CAN FIND CORAL CONSTRUCTION OF CORAL REEFS CONDITIONS FOR GROWTH OF CORAL REEFS TYPES OF CORAL REEFS THREAT TO CORAL REEFS
Our increased appetite for coastal area living, a preference that will likely develop as global temperatures increase, coupled with a rise in seaborne trade and transport, will all contribute to the shaping of future tropical marine ecosystems. Between the years of 1980 and 2000 seaborne trade was shown to increase by 37%, and has continued steadily ever since (Peters 2001). The global mean of ocean transportation is widely acknowledged as a dominant vector regarding invasive species introduction (Carlton 1985), by means of the translocation of larvae and marine microorganisms. One investigation conservatively reported ballast water containing 8 different animal phyla and 5 protist phyla consisting of a total of 81 species (Chu et al., 1997). It is also suggested that at any one moment in time, 10,000 species are transported through ballast water globally (Carlton 1999). An example of a successful invasive transfer via ballast water is the invasion of the comb jelly, Mnemiopsis leidyi, which invaded the Caspian Sea in 1982 (Ivanov et al., 2000). Another ballast water mediated species in recent times is the Pacific brittle star species Ophiactis savignyi, which has now successfully integrated into the tropical West Atlantic (Roy and Sponer 2002). Various management strategies have been manufactured to prevent these ballast tank related problems,
Coral reefs are systems of large, underwater structures that are composed of the mineralized bodies of corals. These corals are a class of marine invertebrates known as Anthozoans, and belong to the phylum Cnidaria, and are thus related to sea anemone and jellyfish. Each individual coral animal is only a few millimeters in diameter, and a few centimeters in length. Due to their sessile nature, and their ability to reproduce asexually, they are able to construct, over many generations, massive colonies of genetically identical individuals. Additionally, they secrete a hard exoskeleton of calcium carbonate to support and protect their bodies, and it is from this process that the colony constructs what is known as a single coral “head.”
The body of the shrimp is two parts the thorax which is the body and the head , the body pieces are connected by the cephalorax and a narrow abdomen. The mouth if the shrimp works with the gills so they can be used. Shrimp have a hard shell that keeps everything together and protects them, its legs, eyes, and rostrum grow out of the hard shell. The use their nose or a sharp peak which there there basically the sing thing to protect their self from all the bigger and other animals it come in contact with and it sticks them with and it has a length that the shrimp lets out to be able to reach where the shrimp wants to get the other animals. Shrimp have some similarities to fish like when they travel, breed, and eat its usually done in schools (schools area group of the species). A (shrimp) single female is capable of producing a large number of offspring, one shrimp can lay up to one million eggs in a single session, take two weeks to hatch it takes two weeks to
The major thing about Mr. Wallace’s article is his concern about suffering of Lobster which he briefly explain the facts, he’s article feature the Maine Lobster Festival in Maine which the festival will cook 25,000 pound of lobsters, the World Largest Lobster Cooker as they call it, lobster will be cook in a gruesome way which he is concerned. Mr. Wallace characterized the lobster that boiling them is really hard for him to watch. Example is in his article he said that “Lobster looks like they are suffering as they hang their claws in the pot”. But this explains why the violent reaction of lobsters to boiling water is a reflex to noxious stimuli. And to add, Based on review by the Scottish animal welfare group Advocate for Animals released reported, a scientific evidence that strongly suggests that there is a potential for lobsters to experience pain and suffering. This is primarily because lobsters and other decapod crustaceans have opioid receptors and respond to opioids analgesics such as morphine in a similar way to vertebrates, indicating that lobsters' reaction to injury changes when painkillers are applied. The similariti...
In “Chapter 6 – The Sea Around Us” of Elizabeth Kolbert’s The Sixth Extinction: An Unnatural History, the author reveals the fact that the ocean is acidifying due to human activities, such as burning fossil fuels and deforestation. In this chapter, Kolbert notes that there was a lack of biodiversity near the vents at Castello Aragonese in order to present the oceans’ future possibility. One of the types of sea creatures that ocean acidification would devastate are the calcifiers, which are organisms that create shells or skeletons made of calcium carbonate (Kolbert 117-122). Credible sources of information, such as the EPA and the Smithsonian Institution, agree that ocean acidification poses a serious threat to marine calcifiers,
Clincher: Unless we change the way we view our oceans, jellyfish might be the only seafood on the menu in the near future.
Occasionally, a giant squid will wash up on shore or will come up in a fishing net, which has allowed scientists to get a close observation of these squid and their anatomy.
First of all, an octopus is a cellapod. Which means it has a soft body, and no bones. An octopus also has eight arms, large useful eyes, and suction cups. ( Octopuses and Squid, page 6 by: Tori Miller.) All of these traits are mostly used for hunting. Eight arms come in handy when your prey is fast and can get away easily, large eyes are useful when you need to see in the dark or the depths of the ocean, and suction cups are used when they need to grab hold of something.( Octopuses Squid, page 14.) ( National Geographic, Octopus Facts.) Octopuses have blue blood caused by copper and bag like bodies. When born they're 1/4 of an inch and don't rely on...
