Thaumoctopus

Structurally, squids have only small variations of a basic theme common to all cephalopods. They are spherical or cigar-shaped with two fins used to stabilize movement when swimming. Ten arms are easily distinguished emerging from near the mouth

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.

Camouflage being one of the most impressive aspects of octopuses' intelligence, scientists under the direction of Antonio P. Cribeiro, conducted an exercise designed to see to what extent the skin of octopuses was capable to adapt to its surroundings. The experiment was divided into three parts:

Deep in the west coast rainforest there is an endangered species called The Pacific Northwest Tree Octopus. They are 30-33 cm amphibious, that scout their lives through touch and sight. The Tree Octopus spends the beginning of its life in the rainforest. The rainforest has so much drizzle and dew, it keeps the threatened species from becoming shriveled and dead. The exceptional and profound creature has a very large brain to body ratio.

Thaumoctopus mimicus is said to use imperfect mimicry, defined as the using poor to decent imitations of multiple morphs, rather than strong resemblance to one species (Hanlon et al., 2008; Huffard et al., 2010). As mentioned in the previous section, they replicate the coloration of multiple forms of flatfish, but more dramatic morphs are displayed while individuals are swimming in the mid-water range of the water column or while interacting directly with aggressive species (Norman et al., 2001). Following with the assumption that T. mimicus is a Batesian mimic, the forms that individual octopus use while swimming higher in the water column are those of well-known toxic or unpalatable species. A variety of dive

The Caribbean Reef Squid, Sepioteuthis Sepioidea, is one of the most exotic and alienated creatures in the ocean. Being one of the most intelligent invertebrates, they only get to about 12-20cm in length and have torpedo-shaped bodies with 10 tentacles “fixed to its head”, and are arranged in a circle around its mouth. The Reef squid is fairly common, especially around Florida, Bermuda, South America, and the Bahamas, and travel in schools (4-30) and aren’t scared of divers, if not curious about them.

Another way creatures survive is with camouflage. Octopi are one of the most know marine creatures that camouflage.

Theses tree octopuses have some similarities to humans and differences as well. In one way that they are like

It was correlated to environmental temperatures, since phylogenetics could not be the case with 1-5 species of octopus sharing the same genus. Ocean temperatures vary greatly across small ranges: this is shown with specie 5 compared to species 4 and 1. Although they are very close to each other, the temperature where specie 6 lives is about 8 degrees Celsius lower than species 1 and 4, which is a huge difference in temperature sensitivity.

The Blue Ringed Octopus is one of the most beautiful and intelligent creatures. It is

On the brain of a mammal, once external stimuli affects a person, pressure is put on the paraventricular nucleus of the thalamus. The paraventricular thalamus (PVT) is a stress sensor that is activated once influenced by physical and psychological stressors. Studies show that the paraventricular nucleus of the thalamus controls a part of the amygdala, and the interaction between the neurons of the central amygdala and the paraventricular nucleus of the thalamus is a step towards modulation of fear as it forms a stable foundation of fear memory and manifestation of response to fear.

Everyone might have once imagined dark environments and scary creatures which live in the deep sea. These childlike dreams are visualized in the popular novel, Twenty Thousand Leagues under the Sea. In the novel, the main character, Pierre Aronnax, searches for a mysterious sea monster while fighting with scary undersea creatures. Although many undersea creatures have been depicted in the novel, one of the striking deep sea creatures would be a giant octopus. This octopus is depicted as a scary creatures that threatens the main character. Many people might think the creatures are fake, but the giant octopus exists, which is also well known by today’s scientists.

These octopuses are just changing their forms and adapting to become stealthy ninjas of the sea. Just three-tenths of a second is all that they take to camouflage themselves. The octopuses change their colors and patterns without notice. This process is called a rapid adaptive coloration. For example, the chameleons have a slow change in color, forms, and a different limited repertoire. However, octopuses have this quick change in color if they ever felt that danger surrounds them. They would amend the color of their skin to the color of a stone. Octopuses are highly intelligent and gifted animals. According to science, they have most of their neurons in the nerve cords of their arms and the remaining in their brain. This gives them a highly sophisticated nervous system. Octopuses are kind of like puppies sometimes. They are playful and can be found at times to toss empty rocks or bottles and catch them in sort of a playful manner. Like all puppies or most of them, they can be trained to distinguish between patterns, and sometimes, shapes. Octopuses are such magnificent creatures that they can be occasionally seen in cargo ships stealing crabs due to hunger, like the bandits of the sea. Sometimes, I wish I were an octopus, so I can change the color of my skin whenever I want to and escape the things that I never wanted to take part in, without being noticed or even

“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.

Despite the fact that squid and octopus share similar appearances, they are actually quite different in various ways. The major difference between squid and octopus is in their variation of anatomy. Octopus has round shaped head along with eight tentacles that endowed with suckers. On the other hand, squid has triangular body that equipped with propeller fin and hooked sucker. In addition, size is another indicator to differentiate between squid and octopus. Size of the octopus can be varies from few centimeters to few meters. However, squid size can be scale up to more than ten meters in length. Finally, they can be easily distinguished by their movements. Octopus relies on their tentacles to move around ocean floor or land surfaces. Unlike
