If this is true, the authors further argue, this would make O. rubescens may choose prey based on fat digestibility rather than on the amount of calories the octopuses is able to obtain from the food items.

We pride ourselves in good customer service, a warm, friendly environment, and being able to select the best artists for Red Octopus. The octopuses will often concentrate their drill holes near the adductor muscles of the bivalve prey.Ī recent study has suggested O. WELCOME Red Octopus Tattoos is a family-owned and operated business, established back in 1992 by Dottie and her late husband, Easy Fortner. Following the capture of bivalve prey, it will often drill a hole through the shell to deliver venom and more easily open the shell. rubescens will pounce on prey and display a stereotypical sequence of color changes at the moment of capture. rubescens have also been observed in the wild to consume krill.Īs part of its feeding behavior, O. The two studies on the subject determined diets in Puget Sound, Washington to be dominated by gastropods, particularly Nucella lamellosa and Olivella baetica, but also composed of clams, scallops and crabs. So far, very little quantification of its diet in the wild has been made. rubescens is a generalist predator and has been maintained on a wide variety of gastropods, bivalves, crabs and barnacles in the lab. rubescens was the first invertebrate in which individual personalities were demonstrated. The presence of individual personalities is a hallmark of intelligence, and O. rubescens is thought to be among the most intelligent of invertebrates. Intelligence See also: Cephalopod intelligence The two can be differentiated by the presence of three eyelash-like papillae below the eyes of O. It can be easily confused with small individuals of Enteroctopus dofleini in the northern end of this species' range. Color can vary from a deep brick red, to brown, to white, or mottled mixtures of the three. rubescens can change its color and texture, making its appearance highly variable. Adult weight is generally 100–150 grams, but animals up to 400 grams in weight have occasionally been observed. rubescens generally grows to a mantle length of 8–10 cm, and arm length of 30–40 cm. The majority of the time it will be fully camouflaged to match its surroundings or displaying a softer tone of pinkish red.O. However, it is rare to catch a glimpse of this octopus in that color state.

It can be described as “ruby red.” This is why it is also known to some as the ruby octopus. In its uncamouflaged state, the East Pacific red octopus can take on a unique tone of red.The East Pacific red octopus, however, was the first to bring this to light.

This resulted in the confirmation that this trait is present in nearly all octopus species. This led to further observational experiments for the presence of this trait in other octopus species. The first documented evidence of an octopus displaying unique behavioral traits which could be identified as individual personalities came while observing an East Pacific red octopus in captivity. Octopus rubescens (Commonly the East Pacific red octopus, also known as the ruby octopus, a preferred common name due to the abundance of octopus species.It is as if it were gloating or congratulating itself on a “good catch.” When it captures its prey, it engages in a rapid color change of its skin.In other words, the octopus literally jumps on top of the prey engulfing it in its arms and webbing. Once they do it emerges and captures it.īoth methods of hunting used by the East Pacific red octopus culminate in the capture of the prey through the use of a pouncing technique. This is when the octopus remains in its secured den and simply watches for potential prey to come close. The other method which is used by the East Pacific red octopus to catch prey is that of lurking. This allows it to remain unseen from predators and also to allow for potential prey to get close unaware of its presence. Fortunately, it has an excellent ability to camouflage itself. The purpose of this behavior is to either actively encounter edible prey or to have edible prey inadvertently come within its grasp.ĭuring this method of hunting the East Pacific red octopus is often exposed on the seafloor. The first method involves the East Pacific red octopus emerging from its den and advancing short distances on the ocean floor pausing every few dozen meters and perching itself on a secure spot. The limited number of studies of this octopus in the wild indicate that it prefers to use one of two methods to catch its prey. As all octopus species are, the East Pacific red octopus is a hunter.
