The common name for this brilliant marine invertebrate is the Blue ringed octopus. It also has a scientific name Hapalochlaena Lunulata. In Latin that means, “Soft skinned thing with little moons”. This octopus belongs to the phylum Mollusca, class Cephalopoda, genus Hapalochlaena, family Octopodidae, kingdom Animalia and order Octopoda. With at least 50,000 living species, the phylum Mollusca is one the most diverse groups of animals. This octopus is in a class that also includes squid, cuttlefish and nautilus. The blue ringed octopus is normally a light brown to dark yellow color but the color changes to glowing yellow-brown with shimmering blue rings when it’s disturbed. It has eight powerful tentacles that can grow to about 10cm long and that encircle the head. They only weigh up to 28 grams and their body gets to 5cm, being the size of a golf ball. They have well established eyes with an image forming lens and large retina but their vision is known to only be black and white. Being soft bodied the only hard part of the octopus is the beak. Their brain is centered about their oesophagus and is shaped like a donut. These octopuses have poison glands that discharge two different types of poison; one they use for catching food, which is the more mild type, and then there’s the type they use for defense, the more poisonous type. The Blue ringed octopus can move several different ways. One way is by drawing water into a cavity in its body, and then dismissing the jet of
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
A) The organism I chose was the blue whale. The blue whale (scientific name: Balaenoptera musculus) is the largest marine animal with the weight of about 180 metric tons (180,000 kg). They weigh around 150-170 metric tons (150,000 kg) together with a length of about 27m (89 feet). The largest blue whale ever measured was 190 metric tons (190,000 kg), and the longest whale recorded was 33.6 m (110 feet). It is the biggest animal ever discovered (so far). The head only cover 1/4th (25%) of their entire body length. Color: Blue whales are blue-gray in color with white patches covering their body. The undersides of the flippers are lighter in color, and sometimes white, while the underside of the tail is dark. In Antarctica, the North Pacific, and the North Atlantic,
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.
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.
Key traits were noted out of 73 lab-bred octopuses. Discoveries showed temperamental variations at different maturity levels. Young octopuses tended to be active and aggressive whereas more mature ones tended to be more alert and quick to react to danger (Scigliano, 2003). Evidence that even though their lifespan is short their brain evolves and adapts quickly.
The legs carry the octopus and the head keeps the legs in control. But if an octopus isn't proportional, maybe the head was too big for the legs or the legs were too big for the head, problems would arise. This is a lot like needing a well balanced government. A federal government is a government which equally divides its power amongst one large government and smaller governments within itself and also has a high belif in federalism, which is the practice of dividing the state and central governments. In the US this can be seen through the national government and state governments: a good, evenly balanced octopus.
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
In 2004, the giant squid had been discovered in deep, inky waters (Schembri 1). These creatures had frequently been misconstrued as monsters throughout history, in sailors’ yarns, wives tales, and even official reports. With a length of 40 to 42 feet, the leap of faith does not seem so difficult. (Giant 1) Giant squids are not known anymore to sink ships like their Kraken persona, but they are extremely territorial, even fighting sperm whales to protect their homes (Coppens 4). Despite being capable of eating just about anything with meat on it, Giant Squids mainly feed on small fish and clams (Schembri 1). For millennia, the giant squid lived in the realm of legends. Its existence lied in the study of cryptozoology, or “the pursuit of wildlife
In the article “Deep Intellect” by Sy Montgomery, he traveled to the New England Aquarium to meet an octopus named Athena and learn her thought processes. She was an enormous creature that could shift shapes and colors while releasing a venomous ink, yet he believed there was more to it than that. Montgomery knew that octopuses were invertebrates so he assumed they couldn’t possibly have a bit of intelligence. However, researchers came to conclusions that they experience feelings and are intelligent like us. One day when he was with Athena, he touched her and entered the parallel worlds they live in. Slowly their eyes met and she grasped onto him with her suckers to greet him. As he rubbed her, he noticed a transformation in her color as she
Although the venom for humans is very seldom a fatal wound, it will still deliver a painful than hell wound even though it’s dead, which sucks. The venom is there to help immobilize prey and kill it so that the organism can feast upon the meal after all is said and done. Then the tentacles bring the meal to the little bubble like head for the organism that make up the Man of War to feast upon.
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.
The scientific name of my organism is Physalia physalis. It’s more commonly known as the Portuguese man-of-war or bluebottles. I live in Navarre, Florida and I came across this beautiful organism while it washed up on shore at the Navarre beach. You can find them in the open ocean in the Atlantic Ocean, the Pacific Ocean, the Indian Ocean, and the Caribbean.
Squids, an animal that lives in water, knowns as cephalopods. It also has a scientific name; Teuthida. Squids are capable of jet propulsion, walking, swimming and sometimes flying… Yes, flying! Jet propulsion! It has another definition when it comes to an animal that lives in water but it’s original physical definition is the jet of matter passed by the thrust produced in the opposite direction, to direction of movement. Furthermore, Newton’s third law states that the motion of body is propelled in the other direction of the jet. Jet propulsion occurs when the squid wants to speed up, their fins (Fig.1) propel themselves in water and then water gets in mantle cavity and above the gills, then reaches an opening by the head. The mantle cavity’s
What is these creatures? Squid and Octopus are categories in sub-marine animal. Squid and Octopus are still one family, both of these animals are The Cephalopoda family. What is Cephalopoda? “Cephalopods, is the class of mollusks which scientists classify octopuses, squid, cuttlefish and nautiluses, can change color faster than a chameleon. They can also change texture and body shape, and, and if those camouflage techniques don't work, they can still "disappear" in a cloud of ink, which they use as a smoke-screen or decoy.” (Wood,2017) This species is common find in ocean or seas anywhere. Both of it are interesting sea creatures, but they are differed in their physical characteristic also have similarity from many aspects. Some people has
