The giant pacific octopus is in the kingdom Animalia because it is multicellular, eukaryotic, and has no cell walls. In addition to this, the giant pacific octopus reproduces sexually and has cells that are used for specific functions. (Kalupa, 2012)
The octopus is in the phylum Molluska. It is under Molluska because the octopus has a soft body (mollus meaning soft), and is a cephalopod. It also has bilateral symmetry. (Kalupa, 2012)
The giant pacific octopus’s class is Cephalopoda. This means “head-foot” and is so named because the arms, or feet, are attached to the head. In addition, the octopus has a closed circulatory system and a large brain. (Kalupa, 2012) The giant pacific octopus is under the order Octopoda because it has arms with sucker stalks that are broad, muscular cylinders. It has no funnel valve and no nuchal cartilage. It has eight arms and no shell which also are common characteristics of a cephalopod. (Kalupa, 2012)
The octopus is under the family Octopodidae because it has suckers in a one or two series. It also does not have a detachable hectocotylus, which is...
In the phylum Mollusca, there are many organisms that have body parts that change as the environment around them change; such as the octopus. An octopus can camouflage to variety of objects in its environment. Each organism in the Mollusca phylum has a type of foot that stows mobility and they eat by a radula. The radula is strap like tongue that has very sharp teeth and they can change to be different shapes or sizes based on their prey. They have a pseudo coelomate body plan, meaning that they have a coelom that exists, but it is lined by mesoderm only on the body wall, not around the gut. This video enhanced my understanding standing of the phylum Mollu...
“Their habitat lies on the Eastern side of the Olympic mountain range, adjacent to Hood Canal.”. Because of the moistness of the rainforest and their specialized skin, they are able to keep from becoming desiccated for long periods of time, but if they get the chance they would prefer resting in pooled water. The tree octopus explores the world by both touch and sight. Tree octopuses have eyesight comparable to human. Besides the fact that it allows them to see their prey and environment around them, it helps in inter-octopus relations. Even though they are not social like us, they show each other their emotions through their ability to change the color of their skin: red indicates anger, white fear, while they normally maintain a mottled brown tone to blend in with the background. (Lyle
The main anatomical features of this class are as follows: cartilaginous skeleton, ampullae of lorenzini, dermal denticles, and pectoral fins (Natalia Riusech and Diego Arias, Natural History of Vertebrates). A cartilaginous skeleton, the defining feature of Chondrichtyhes, allows the fish to swim more efficiently due to the elastic nature of cartilage. However, all of the Chondrichthians must swim or else they sink due to the lack of a swim bladder (Classes Found in the Phylum Chordata). Some species within the class Chondrichthyes include the Great White Shark, Tiger Shark, Bat Ray, Mobula Ray, Eagle Ray, and the Whale
When someone says the word octopus, an image of an eight legged invertebrate comes to mind. The body structure of a mature octopus is very interesting. Octopuses are extremely intelligent. They have excellent memory can use tools, and are great problem solvers. Only birds and mammals are known to be smarter. Each one of their tentacles, which are used for prying open clam shells, has two rows of suckers that can give them a pretty good grip. An octopus also tastes with its tentacles. An octopus’s third right arm, also called hectocotyli, is also its penis which a male octopus will use to mate at one or two years of age. The only part of an octopus that cannot move or squeeze through small spaces is its beak where it consumes food. This is used for biting and also breaking things apart. Did you know that octopi have three hearts? This is because these sea creatures have extra legs and three hearts are necessary for better bl...

The five kingdom system has developed with time. Living organisms were first grouped according to how they moved, with plants in one kingdom and animals in a second, by Aristotle during the 4th Century BC. In 1700s Linnaeus developed the system of naming organisms, which we still use today, called binomial nomenclature; this system solves the problem of the same species being called many different common names according to region and makes it easy to distinguish between two organisms. To write the scientific name for an organism the Genus name is written first and capitalised and the species name second in lowercase all italicised. In 1894 a third kingdom was added by Ernest Haeckel. This third kingdom was named Protista and contained single-celled eukaryotes and bacteria. Herbert Copeland divided the kingdom Protista in 1956 and created the kingdom Bacteria, this was prompted by the discovery of immense differences between single-celled eukaryotes and prokaryotes (bacteria). Finally in 1959 Robert Whittaker added divided the kingdom Plantae into plants and fungi. Later, 1977, Carl Woese divided the kingdom Bacteria into Eubacteria (true bacteria) and Archaeabacteria (ancient bacteria), this division, although important, is often disregarded in lue of the simpler 5 ...
Squidward Tentacles is an employee at the Krusty Krab. He is a 34 year old male. He resides in Bikini Bottom. His hobbies include playing his clarinet and painting multiple pictures which he has false hope will one day be published in some museum. He has hatred for going to work, and is horrible with customer service. He exhibits a strong desire to fit in with a higher caste than himself. There have been many episodes though where when given the chance to prove himself worthy of a higher caste he will retreat to a safer place like his house. His esteem level seems very low. He never leaves his house other than for work either. He hates being social and that’s very obvious in every action Squidward carries out. He rarely dates and when he does there is never a second date. He is a healthy man of his age. He really doesn’t have many friends. There is his two neighbors Spongebob Squarepants and Patrick Star, they want to be friends with him but Squidward can barely tolerate either of them. When he is sad he usually turns to his music, painting, or bubble baths which he takes very often. His life goal or aspiration is to be a famous artist and musician. He’s a very smart individual but has absolutely horrible social skills.
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.
Crustacea is a large subphylum of Arthropoda, consisting of almost 52 000 described species, including animals like crabs, lobsters, shrimp and barnacles. The majority of these are aquatic, living in marine or fresh water environments, though some have adapted to living on land like some crabs and woodlice. Most crustaceans are relatively small, though there are some exceptions. All of them have a hard, strong exoskeleton, divided into two parts, which has to be shed in order to allow the animal itself to grow. They have a large circulation system, where blood is pumped around the body by the heart. Only some crustaceans have sexes separate, and those that are usually mate seasonally and lay eggs. The study of Crustacea is called carcinology.
Have you ever wanted to slap eight people at once? Or if you're more of a mushy, touchy, feely person, have you ever wanted to hug eight people at once? An octopus can do either or both of these if they want to! So you know an octopus is lucky being able to do this but what's an octopuses habitat? Since they can slap eight things at once do they have predators? Or since we're on the facty facts subject where do they live?
A final example of a commensal relationship is a titan triggerfish. It is often referred to as giant triggerfish because of its size ad belongs to the Animalia kingdom and the balistidae family. It has the ability to develop and generate feeding opportunities for smaller fish. It can move large rocks that are too big for the small fish to move by themselves.
In 350 BC, the Greek philosopher Aristotle, who was arguably among the most intelligent men in the world, wrote in his History of Animals that the octopus is “a stupid creature, for it will approach a man’s hand if it be lowered in the water” (Nuwer, R. 2013). However, Aristotle was inaccurate in his depictions since in actuality, the octopus is one of the most complex and intelligent creatures of the sea. Research has indicated that octopods not only demonstrate a strong problem-solving ability, they possess unique personalities and cognitive abilities that allow them to navigate through mazes and learn through observation. Unlike other species within the Mollusca family, Octopods are especially known for their high degree of intelligence.
Porifera is the most simplistic phylum under the kingdom Animalia. The sponges have no tissue layers, but instead an interior and exterior layer with a gelatinous middle layer that separates the two. They are the only phylum with asymmetrical symmetry. Throughout the advancing phyla it will be shown this trait is lost. Porifera lacks a proper digestive system, but a canal system allows the sponges to filter feed. Along the inside of a sponge, flagella pump water through the sponge’s body. This process brings in oxygen and other small organisms and then flows out the top of the sponge, the osculum, removing waste by diffusion. Sponges lack a circulatory system, as does many of the first couple of phyla. A coinciding factor could be their small size. A nervous system is also missing, but very basic nerve cells within the pores sense the water currents. Gas exchange occurs through these pores. Reproduction in sponges can be asexual by budding, gammation, or fragmentation. Some sponges can also have sexual reproduction occur as an egg gets released and fertilized in the open water by free floating sperm. After this stage they cling onto rock and begin their sessile, basic, life....
