The Cannonball Jellyfish
The Cannonball Jellyfish is a species of jellyfish in the family Stomolophidae. It is a blueish brown bulb shaped similarly to a cannonball and thus has radial symmetry. For defense, it stings whatever gets close enough with its short jelly-shrouded tentacles covered in nematocysts. These nematocysts also dispense a mucus containing a toxin that scares away most predators.However, the venom that is used is rather impotent.For food, they trap small prey like plankton or larvae by trapping them in their mucus-covered mouth-folds. They move around by either following a current, or moving in such a way that they are propelled vertically in the way they are facing. These balls of fun generally live

After such, it goes into the strobular stage, and begins to segment and reproduce. They reproduce asexually, but they can also produce via sperm and eggs during their medusa state. It lives mostly in the South-Eastern US and Gulf Coast regions, usually in waters in temperatures around 23.1 degrees Celsius. It turns out that they may have medicinal uses, such as helping with arthritis, and bronchitis. The cannonball jellyfish known as the Cabbage Head Jellyfish, and is considered a delicacy in Japan. So much so that it has been a huge problem. In many such areas that this jellyfish inhabits, it is either incredibly overpopulated to the point where it is causing water problems, or being very over-harvested, and harming the ecosystem. They can especially harm the leatherback sea turtle, as these jellyfish so happen to be their main food source. It does not help any that the leatherback sea turtle is endangered. The Cannonball Jellyfish is also incredibly quick to go stale, so they are processed as soon as they are caught. They are among the most harvested in the fish market, and also one of the most populated. While Cannonball Jellyfish are being harvested, some fishermen and fisherwomen
Moon Jellyfish are in the “Animalia Kingdom, Phylum Cnidarian, Class Scyphozoan, Order Semaeostomeae, Family Ulmaridae, and Genus Aurelia” ( Myers, 2016 ; Espinosa, ; 2016 ; Parr, 2016 ; Jones, 2026 ; Hammond, 2016 ; Dewey, 2016). The morphological description of Cnidarians are corals, sea anemones, jellyfish and hydroids. These cnidarians form a diverse phylum that contains ~9000 species, which live in aquatic (predominantly marine) environments. The phylum-defining trait of Cnidaria is the stinging cell, the nematocyte an extrusive organelle used for predation, adhesion and defense (Holstein, 1981; Lengfeld et al., 2009; Tardent and Holstein, 1982) (Steele and Technau; 2011). Also, this phylum, Cnidarians, are divided into two groups, “Anthozoa (sea anemones, corals and sea pens), which live as
Blue Bottle Jellyfish (Physalia utriculus): has an air sac for a float and long blue tentacles which can be up to 10 metres long (the Blue Button's tentacles are short).
The Portuguese man o’ war which can also be know as the floating terror, blue bottle, and by many other names. It names come from a sailing ship that sailed in the 18th century called the man of war. It comes from the Physaliidae family, and it is a hydrozoan. It is a siphonophore and not an actual jellyfish. It lives in the Atlantic, Pacific, and Indian oceans. It stays towards the top of the ocean and moves with the wind typically. Usually in the open ocean but the tide and waves can move it to the bay. Typically if you find one man of war there’s more not to far off.
As for the blue-ringed octopus, this animal can somewhat compare to a sea wasp when it comes to staying hidden. The blue-ringed octopus can control its dermal cells, allowing it to camouflage itself in the rocks and reefs throughout their respective oceans. Also, the size of the octopus helps its case against box jellies, being that the blue-ringed octopus is no bigger than a golf ball (Barnett). But this could hurt the octopus if it is looked at from another viewpoint; the size of the box jellyfish and its tentacles are the reason that it is above the blue-ringed octopus in lethality. The length of the box jellyfish allows it to inflict more damage, and release more venom than a blue-ringed octopus. By looking at box jellies from this perspective, they are clearly more deadly than their fellow dangerous sea creatures.
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.
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.
Planktons! You can find them in several places on the Earth. In oceans, seas, and lakes! These organisms are those that drift, and are incapable or have little or no ability to swim. Due to that, they are moved and taken wherever by the currents of water based environments. (http://www.sciencedaily.com/terms/plankton.htm) Not to mention, they are also an important food source to many large aquatic organisms. For instance, fish and whales. (https://en.wikipedia.org/wiki/Plankton) In this lab experiment, “Battle of the Plankton”, groups of students are to make their own planktonic organism out of household items that will (hopefully) have the characteristic of sinking slowly when placed in a large tank filled with fresh water. They will have
National Oceanic and Atmospheric Administration scientists Tomo Eguchi and Jeff Seminoff made oceanic history by releasing the first juvenile loggerhead sea turtle into the West Coast of the United States, with a transmitter attacked to its body. This exploration is going to aid scientists in getting a better understanding of what type of habitats juvenile loggerheads live in prior to participating in the years prior to participation in migration. Scientists are hopping to gain a better understanding of where juvenile loggerheads live for the sake protecting their habitats from fisherman. As of now, scientists have predicted that juvenile loggerheads tend to inhabit the same environments as swordfish. This is extremely dangerous to the lives of sea turtles considering that swordfish are heavily hunted by many fishermen. Therefore, if scientist theories are correct, the loggerheads are living in very dangerous environments. This exploration was initiated when a Coast Guard vessel found the loggerhead and took it to the Aquarium of the Pacific, where it would receive medical attention.
When the freezing point for water is 32 degrees fahrenheit (0 degrees celsius) what happens to life beneath the ocean when temperatures plummet in Antarctica? There has been recent discoveries of antifreeze proteins in Antarctic fish. Dr. Arthur DeVries was the first to discover such proteins, in the 1960s, and describe how they bind in the blood of fish to ice crystals and prevent the fish from being frozen.
In the original listing from USFWS (1978), the loggerhead sea turtle was listed as threatened throughout all of its range. The document goes on to state that one of the main threats to the loggerhead sea turtle was that it was being harvested for the shell or as food; the eggs were considered a desired food item and protein source. Regulations were put in place to protect the loggerhead sea turtle such as prohibition of foreign commerce, importation, and exportation
The purpose of this experiment was to explore how an organism’s internal environment is affected when exposed to different external environments, the eggs modeling humans.
Hawaiian bobtail squid, also known as Euprymna scolopes is a species of bobtail squid in the family-sepiolidae. Native to the Pacific Ocean and can found in the shallow coastal water of Hawaii-island and Midway island. It has a relatively short life span (3 – 10 months). However, it grows quickly and hatching, reproduce can be undergo after 2 months. Female which lay egg on the underside of coral ledges in shallow will die shortly since they can breed only once. Hawaiian monk seal, common predator of it. Hawaiian bobtail squid can grow up to 30mm in mantle length.
Irukandji jellyfish are a clear, very small jellyfish with a maximum body size of only twenty five millimetres. These jellyfish can unleash an extremely painful sting that without treatment, can kill a person. The Irukandji have been found off the coast of northern
Before attempting this lab, we conducted some research on what conditions catfish need to survive in an area. Catfish are better off at temperatures ranging from 88-90 degrees Fahrenheit. Their preferred dissolved oxygen levels are at least 4 ppm.(http://www.thefishsite.com/articles/1907/water-quality-monitoring-and-management-for-catfish-ponds/). The diet of catfish often changes as they age. Younger catfish primarily feed on aquatic insects such as dragonfly larvae, water beetles and fly larvae. By the time they're adults, catfish consume small fish, seeds, aquatic plants, algae, crawfish and snails.(http://animals.mom.me/catfish-eating-habits-9466.html). The alkalinity of the water needs to be at least 40 ppm but the catfish will be happier
Flashy and colorful signs at every concern, purposely attempting to catch the eye of hungry consumers. Even packaged food from the regular grocery seems satisfying to the eye with whimsical titles and commentary. It is quite deceiving with the lively presentation, hiding the truth about the potential harm of fast food and packaged food. In the song, “Superfast jellyfish” by Gorillaz, a well-known band that is represented with animated characters, discusses about consumerism. The fast food industry, still successful, has had a major impact on the people eating habits. In this particular, the subliminal message in “Superfast jellyfish” about package food and massive fast food chains in society through pathos and figurative
