Organism Physiology
The enter octopus dofleini has evolved advanced organs that have been an important part of the species survival. All though very odd looking, and somewhat looking like a creature from another planet. The animal’s eyes and arms have adapted perfectly to capture its food. The octopus has the ability to blend into their environment by changing their color to comply with the environment they are in. This is somewhat of a natural built in camouflage to help the octopus catch their prey. The octopus also has the ability to change colors because they have light sensitive skin cells which are called chromataphores. These cells contain special pigment granules which ultimately give the octopus the ability to change colors.
The brain of an octopus is located below the eyes and goes around its esophagus. There are sensory organs within the brain that are the most developed when compared to any other invertebrate species. It is thought believed that more than 75% of its brain is concentrated to its optical system and memory. This feature allows the octopus to remember the areas of the environment it lives in and what is the best place to feed. The octopus’s memory is a major factor that works to its advantage for its survival.
Another survival mechanism that the octopus has is that when the octopus in put in a stressful or dangerous situation, the octopus can spray out a dark ink cloud. The ink is made mostly of melanin and mucous, and tyrosine. The ink can confuse a predator by irritating its eyes and interfering with the predators senses of smell. Another survival mechanism that the octopus has is that it has the ability to detach one of its limbs. The detached arm will continue to twitch, in hopes to distract the predator. This is a very unique survival feature the octopus has, and truly helps the octopus survive within its environment.
The octopus has eight appendages. These arms are what moves the octopus through the water and gives the octopus the ability to move and crawl on the ocean floor. There are suckers located on the underside of each arm of the octopus. The suckers have the ability to latch onto its prey and can be used as a weapon to defend against predators. Each sucker has up to ten thousand neurons in them (Horton, 2014).
During mating, the male octopus will detach one of its arms which are used to help them to put sperm into the female octopus. The male octopus usually dies after a few weeks of impregnating the female octopus. In conclusion the octopus has seemed to evolve very well to its environment. The octopus survival mechanisms to the human species may seem extreme, but for the survival of the octopus are necessary. That fact that the octopus’s bain is large and the octopus has a good memory gives it an advantage when compared to other animals in its environment. The octopus is a very strange looking animal, but because of its complexity and survival methods make it one of the most interesting species in the ocean.
