Blue Ringed Octopus

“Everything in Australia is trying to kill you, haven’t you heard?” (Rosalind James). Physalia, or Portuguese Man of War, is a salt water species of hydrozoa that thrives in dead zones of tropical and subtropical waters. The animal is often confused with a jellyfish, but it actually is a siphonophore. Blue Bottle, Physalia, is not just a multicellular creatures called zooids. The zooids work together to provide defense, help with feeding, to produce offspring, find a safe habitat, and use all the tools necessary to live a full life. While movement and shape are uncontrollable, they play a vital role in the creature living. The Portuguese Man of War is a beautiful creature that plays in an important role in the ecosystem

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

This cartoon goes by a few names, but the Standard Oil octopus is the most common, it was created by Udo J Keppler in New York and wad published in Puck magazine on September 7th 1904. The cartoon depicts a standard oil tanker as an octopus it has its tentacles wrapped around Congress, state capital, the shipping industry, the railroads, and other business owners or politicians. The only thing that the octopus does not have control of is the White House, its eyes are fixed on it but its tentacles are just hovering above it not able to grasp it, the reason for this is because of President Roosevelt using the Sherman Antitrust Act to regulate the monopolies. The point Kepler was trying to get across the importance of regulating Standard Oil to prevent them from monopolizing farther in controlling the entire country, which at the time they already pretty much did.

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.

There are many Cnidarians that live and thrive in our tropical waters. Although most are harmless to humans, there are some that can kill you in a matter of minutes. The Cnidarians defend themselves with their stinging cells called nematocysts. When a predator or threat comes too close and brushes against its tentacles, it injects toxins into the blood stream and often effecting the nervous system. In most cases, if a very dangerous jellyfish is spotted along a stretch of beach, the life guards will close down that beach.

One of the most damaging algae species known to Florida along the south-west coast is the Karenia brevis, also known as Florida red tide. These microscopic algae bloom all year around in the Gulf of Mexico producing brevetoxins, which contains a suite of neurotoxic polyether compound. These blooms can last as long as 18 months fluctuating between insignificant blooms to critical, impacting both the marine ecosystems and humans health (Pierce and Henry, 2008). The Florida red tide will continue to be the cause of unexplained fish and other animal deaths, along with human illnesses unless more research and observations is done to find a way of controlling these algae blooms.

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.

First, a few octopuses were introduced to a closed glass box (in full view of potential predators) containing items such as rocks, sand, and algae which are found in their natural environments. Unsurprisingly, this resulted in the octopuses adapting effortlessly to their surroundings. Then, the items inside the glass box were replaced by a piece of canvas printed with a geometric pattern, something that an octopus would never encounter in its natural habitat. The colors of the canvas were not random, however, but corresponded to the pigmentation abilities of octopuses. Once again, the octopuses easily completed the task. Finally, the geometric

The 59-year-old author, Sy Montgomery, has written 20 books, each based on a specific research or expedition she has taken part in. Her studies, which she descriptively incorporates into her novels, have warranted her various book awards and acclaims. She plunges herself into the lives and mysteries of Earth’s wildlife in order to gain a further understanding of how particular organisms thrive in their wild, dangerous environments. Although Montgomery was no expert in the field of cephalopods, she quickly learned all she could about the intriguing invertebrates through fellow researcher, experts, aquarists, divers, and colleagues encountered throughout her studies about octopuses. Through diligent research via articles, studies, field

The blue crab, Callinectes sapidus, is one of the most familiar inhabitants of marshes and waterways along the Atlantic and GMx coasts of North America. The abundance of blue crab larvae and juveniles make them important components of the diets of numerous species of fish, invertebrate and avian predators (Van Engel 1987, Guillory and Elliot 2001). As juveniles and adults, blue crabs act as generalist predators on benthic infauna and epifauna; consuming invertebrates, fish, and crustaceans (including other blue crabs) as well as plant and detrital materials (Darnell 1958, Alexander 1986, Meise and Stehlik 2003, Lipcius et al. 2007). It has been proposed that blue crabs are keystone species in the marsh because of their impact as predators

The blue crab Callinectes sapidus is a wide-ranging, ecologically and economically important species along the Atlantic and Gulf of Mexico (GMx) coasts of North America. Consequently, its basic biology, life history, population genetics, and demography have been the subjects of numerous studies. For my dissertation research, I propose to focus on two critical areas concerning the ecology and evolution of blue crabs that have broader implications for our understanding of marine organisms with biphasic life cycles. For the first chapter I will investigate the unusual finding of extreme temporal and spatial variation in the genetic composition of settling blue crab larvae along the Texas coast. Since it was reported in 1993, this finding been

This lab has taught the scientific methods that can be used to gather and test the data to complete a required experiment.Through the scientific methods I was able to develop a hypothesis and test it by collecting the data. As our hypothesis stated that Blue fish is most dominant in our lake because of less predatory threats.But after collecting the samples of fish from the lake We were not able to prove our hypothesis.As according to the data we collected the blue fish was less dominant as compared to green fish.So we compared our data to average class data but still we were not able to prove our hypothesis as green fish was most dominated in the lake because green fish had less predatory threats compared to blue fish .Thats why blue fish

Gammarus setoseus is a kind of tiny, shrimp-like oceanic organism. Adult G. setosus is typically 20-35mm long (Weslawski 2009), but the organism we use in our research is generally 5-10mm, which can be classified as juvenile. The head and body of G. setosus is covered with grey and translucent thin shell, which have a function of support and protection. On the top part of G. setosus, there are two dark black eyes and a mouthpart, as well as two slender extended tentacles. It has a dozen of limbs arranged in two lines under its body, which

A Belcher sea snakes venom is 100xs more toxic than other snakes. Did u know a Belcher sea snake don’t have gills. If it bits you four times you’ll only get poisoned ones.

Look out the window and see what is flying around in the sky. The sky would show some birds, planes, and kites, but it probably would not show an elephant. In the 1941 Walt Disney movie Dumbo, an elephant is able to fly due to the fact that his ears are enormous. What many people do not know is there is a Dumbo flying around in the deep sea. The Dumbo of the sea is not as big as an elephant, but has ear-like fins that help it move around.
