OCTOPUSES: WHAT DO THEY DO? Octopuses, octopi or octopodes are one of the most interesting sea creatures in the world. They have been living on earth since 296 million years ago during the carboniferous period, based on the oldest octopus fossil found. Octopuses along with cuttlefishes and squids are known to be cephalopods which are characterized by a prominent head, a set of arms or tentacles, and 'mirror image’ body symmetry. Since they are invertebrates, they do not have a backbone which makes their beak, which is similar to a parrots’, the hardest structure of their body. Aside from having rounded bodies, bulging eyes, and eight long arms, octopuses have three hearts, nine brains, and copper-based blue blood. According to Eric March (2013), octopuses can do things like: opening a jar from the …show more content…
It is just strong enough to subdue its prey. In addition, their ink cannot harm humans that it can be used as an ingredient in dishes like black pasta. But not all octopus has mild or not harmful venom. There are ones who can really harm humans or worst, it can kill humans. One example is the blue-ringed octopus which lives near in Australia. Their venom causes paralysis that stops breathing. Octopuses are renowned for their intelligence and their use of tools. Certain species of an octopus like veined octopus builds shelters from sea shells, coconut shell, or human debris. An octopus enjoys hiding inside a glass jar that they find on the ocean floor, putting what would otherwise be trash to good use. This reason makes them special and important for the environment. Tests have been conducted with octopuses which showed that they both have long and short term memory. These studies have also helped humans to explore the way in which the human brain is able to store memories as well as to recall them at later times. It is also considered in some countries as food or
This system is able to process information quickly due to the short distances between neurons (Williams, 2011). Williams (2011) notes, by invertebrate standards, octopuses show exceptional cognitive mental capabilities that are rivaled only by some of the “higher” vertebrates, such as chimpanzees, dolphins, and humans. The decentralized design of the nervous system allows for decision making at different levels, i.e.: in the brain, or in the arms, which possess their own peripheral nervous system (Mather & Kuba, 2013; Stolzenburg, 1993). The arm’s nervous system has twice as much “neural firepower” as the brain and contains approximately three-fifths of all the body’s neurons (Stolzenburg, 1993; Williams, 2011). This portion of the nervous system is semi-autonomous, performing with minimal input from the brain but, when necessary, can exert centralized control over the arms (Godfrey-Smith, 2013; Williams, 2011). The arms also contain several sensory organs, including statocysts, olfactory organs and a system that is analogous to the lateral line in fishes (Alves et al.,
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.
The outer tentacles probe for a potential meal, then the inner sensors decide if the prey is edible. They are covered in thick, blackish-brown, water-repellent fur, and have large scaled feet and a long, thick tail. This animal is by far one of the most interesting animals in the world, despite looking like a cross between a rat and an octopus. The way it behaves and utilizes its star nose is fascinating and makes it very unique when compared to other animals.
“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
Although the Hippocampus spp. are placed into the same class as other organisms more traditionally viewed as fish, their morphology bears distinct differences in comparison to other bony fish. The various species belonging under the genus Hippocampus range in maximum size from 20 mm to 300 mm(Foster 8). Their physical appearance is distinct from other members of its class due to their "horse-like head, monkey-like tail, and kangaroo-like pouch."( Lourie et al 12) Morphologically, seahorses do not have scales like traditional fish, but rather posses bony plates covered by skin. The appearance of bony extrusions and skin ...
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...
...t squid eyes ever documented had a diameter of 27 cm, bigger than a soccer ball. However, the squid observed was not fully grown, and therefore it is extremely likely that there are even larger eyes out there in the world. Teuthids have many unique talents, and when they are combined, they create a powerful force, whether defensive or offensive.

I chose an interesting artwork; Octopus Mom, a drawing that is displayed in the CityArts Factory in Orlando. The drawing is of a woman with eight arms in the form of an octopus. Octopus Mom has objects in each one of her eight arms, these objects included a belt, duster and an infant child. The drawing is in a wooden frame and is surrounded around a room full of aquatic drawings. The Octopus Mom was in the aquatic gallery; which was one of seven galleries, this gallery included fish and mermaid portraits, a jelly fish projection and fish tanks with real fish. Octopus Mom portrays the limitless capabilities, independence and nurturing nature of mothers.
You probably think horseshoe crabs are crustaceans, but you’d be wrong. They actually aren’t crabs at all, and there’s more about the horseshoe crab that you wouldn’t believe. This weird-looking marine animal survived two mass extinctions and lived in the Ordovician Period.
Jellyfish, of the Phylum Cnidaria, are an interesting and well developed species. Although they are invertebrates, they are similar to human beings in that they contain an intricate central nervous system that enables them a common perception of their environment. It is understood that several species of jellyfish utilize their nerve net in order to respond to common features of their aquatic habitat, such as: depth of water, light, sound and temperature. They use utilize information from these environmental features to survive in their environment and communicate with each other.
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?
nightmare. I tell him that it felt so so real to me and that I am starting to actually believe that it’s real. He is quiet for a while and then he says
