Males will then slowly move towards a female and insert his hectocotylus arm into the female. Males assume an erect position using all of their arms to support them over their surroundings. When mating, males mount the females in a courtship dance, similar to that of Enteroctopus dofleini. Mating is random and occurs when males opportunistically encounter females. Southern red octopuses are a seasonally breeding species. ( Ortiz, et al., 2006 Uriarte and Farías, 2014) Reproduction Instead, sexual maturity is determined by the size of the reproductive organs and total body size. There is no set time until sexual maturation of this species. The paralarvae, once hatched, move to the surface of the water and continue life as a planktonic species. It takes about five months (168 days) for the eggs to hatch into paralarvae that lack the yolk-sac. During development, the embryos show exponential growth through the metabolism of the external yolk-sac. The total number of eggs laid per clutch varies but is typically over 1000. There are multiple strings from a single clutch of eggs and range from 1.5 to 2 m in length. The eggs have posterior string that is connected to many other eggs from the same clutch. ( "Cephalopods of the world: An annotated and illustrated catalogue of cephalopods species known to date", 2014 Cárdenas, et al., 2011 Marquez, et al., 2011 Ortiz, et al., 2006 Pérez, et al., 2006)Įggs are laid in clutches and individual eggs are pear-shaped and 2 mm in length. On the mantel, the chromatophores are more spaced out. Along the arms the chromatophores are arranged in a linear fashion. Newly-hatched young are mostly colorless apart from the chromatophores on the mantel and arms. Arm length ranges from 5.8 to 9.2mm, mantle size is 7 to 9.5 mm in length, and 5.3 to 8.8mm in width. Hatchlings of the southern red octopus are 14.8 to 21.5 mm in total body length. The eyes of the adults are highly developed and large, 2.32 to 9.82 mm in diameter. Average body mass of southern red octopuses is approximately 4 kg. The total body length from mantle to arm tip, on average, is 1 m. Each arm has numerous suckers (180 to 210) that occur in two rows, arms also have enlarged suckers closer to the mantle. The arm length for this species is approximately 60 cm. Their mantle is about 20 cm wide and has a rough appearance. Southern red octopuses vary in color from bright red to rust and have whitish suckers under their arms. ( "Cephalopods of the world: An annotated and illustrated catalogue of cephalopods species known to date", 2014 Ibáñez and Chong, 2008) The area around the den of the animals are usually littered by crab shells and occasionally the shells of bivalve mollusks. They live in small caves and crevices at a depth of 5 to 140 m. Southern red octopuses inhabit shallow sub-tidal zones of the Patagonian coast. ( "Cephalopods of the world: An annotated and illustrated catalogue of cephalopods species known to date", 2014) This species is found as far south as the southeastern Pacific coast of Chile, as far north as Rio de la Plata in Argentina, and around the coast of the Falkland Islands. It is not known how many copies were made after the edition run ended.The Patagonian giant octopus or southern red octopus, Enteroctopus megalocyathus, is limited to the Neotropical region of southern South America. This includes works made-to-order, or prints on demand. The number of works produced has been determined and included in the listing. This means that every work of art is unique and there will never be another identical one. One-of-a-kind works of art are also known as “OOAK” artworks. Each work bears great similarities to the original. It could also refer to a prototype or a model from which other works can be made. Original Artwork could also refer to the first work, which is always preceding all others. They reach a greater audience than originals and act as a tonic against commodification. While they may be less valuable for different reasons, reproductions and copies have had a tremendous impact on our experience. For workshop paintings that bear evidence of master craftsmanship, this attribution must be further qualified. Mixed media includes oil, acrylic, and watercolor paintings. Original artwork can be any type of painting, sculpture, performance, or other media. Original Artwork refers to any work that is considered authentic and not a copy or imitation of the original works of an artist.
