The Giant Pacific Octopus

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

I think it was a very effective cartoon for several reasons, the first being how the artist used the octopus's tentacles as visual aids to help the viewer see without ever using words what is standard oil industry controlled and what it was going for next, I think it is a powerful and descriptive cartoon that is not something that is easily seen in

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.

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

It can be stated by an identity theorist, there is insufficient evidence to show that octopuses can feel pain or hunger (115). Octopuses are not actually feeling mental state of pain or hunger, but they are instead feeling something that is similar to the mental state of pain or hunger, if at all, as the mental state of pain can only be felt with the physical state of the firing of c-fibers and mental state of hunger can only be felt with a certain physical state. If the mental state pain is the physical state of c-fibers firing and if the mental state of hunger is a certain physical state common in humans, then it is impossible for the mental state of pain and hunger to be felt without certain physical states. Therefore, octopuses do not actually feel the mental state of pain or hunger, but they instead might feel something similar to the mental state of pain and

Have you ever seen or heard of a cool, weird, but yet fascinating creature? This creature is called the southern blue-ringed octopus. I will tell you some interesting facts about this fascinating creature. The southern blue-ringed octopus got its name from its blue rings. The southern blue-ringed octopus doesn’t always have its blue rings, in fact the octopus’s rings can be different colors like light brown, grey, and even yellow. On the upper side of the southern blue ringed octopus is rough feeling with a lot of wrinkles. When the southern blue-ringed octopus feels threatened or gets disturbed the rings change to blue. The cells on the southern blue-ringed octopus that are blue are called chromophores.

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

They use their tentacles to catch prey, and olfactory stimuli help them detect light in order to do so. They feed on other marine invertebrates like copepods and also plankton. In order to move food toward their mouth, they need to use their four long tentacles. These tentacles have nematocysts cells or stinging cells that soften their prey which help them capture their prey easier and it doesn’t cause damage to their tantalizing tentacles. They are also prey to other fish and sea turtles, which makes somewhat of a competition between the

A fun fact about mimic octopuses is they have tree hearts two of the tree hearts pump blood through each of the two gills and the third through the body. If a mimic octopus loses and arm they have four pairs of arms. Scientist says that mimic octopuses are one of the smartest sea creatures there are. As a sea animal it needs to understand predators the way the act and remember their environment and behaviors of other sea creatures they are mimicking as well. Scientist have done test on how well and fast they can open jars to keep themselves safe form predators. Scientist has seen mimic octopuses using the things they have around them like coco nut shells and rocks and jets to get away or. hide. A mimic octopus is a living thing

Have you ever heard of a Dumbo Octopus? Or even better the Grimpoteuthis. If you haven't, I'm here to reveal to you its species. It’s a rare breed of octopus, which is an aquatic animal that lives deep in the ocean. If you wanted to hear more about it then today is your lucky day. I will be explaining new research and everything there is conducted on this animal.

The first thing I am comparing is an octopus to a squid. An octopus has 8 tentacles, and uses all of them to catch their prey. They live in dens on the seafloor. Octopus lose their outer shell and get a new one back. They also have a round head. Octopus lifespan is 3-5 years. It has two eyes and four pairs of arms, and like other cephalopods, it is bilaterally symmetric. It has a beak, with its mouth at the center point of the arms. They feed mainly on worms, crabs, whelks and clams. The giant Pacific octopus feeds on shrimp, clams, lobsters, and fish, and even larger prey, such as sharks and birds. It has a beak, with its mouth at the center points of the arms. Octopuses are ocean creatures that are most famous for having eight arms and bulbous heads. They squirt ink to deter predators; and being boneless, they can squeeze into (or out of) tight spaces. The water depth in which they live ranges from the shallow, coastal waters to about about 330 feet deep. The

“It has many parasitic qualities. It sucks blood like a tick, mosquito, flea, or a leech. Like any parasite it has tricks to help it go unnoticed as it attaches itself. One of these tricks is present in what would be an ink-sack on a normal octopus. In this organism the ink sack is replaced by a robust chemical-factory,” shared the scientist as he pointed to the organ in question with the remote’s built-in laser pointer.

One thing that my group observed on the external anatomy was that the chromatophores on the squid went to a lighter color after rubbing it. Another observation (on the external anatomy) was the beak. It was cool getting a chance to see the mouth (which is under the tentacles), and whenever I looked inside the beak you could see the esophagus. The next

The octopus grabs the bottle and the octopus sit’s on the bottle and he opens the lid and eats his prey.

Predator loss in the ocean is a growing problem in our world today. Sharks are the main loss of predators in the ocean, with a wide verity of species in the ocean Sharks sit at the top of the food chain. They live within the biome of the ocean which has different species living only in certain part of the ocean so the ocean has biomes within its self with shark species with almost all of it.
