Amphioctopus Marginatus - Tumblr Posts

Кокосовый осьминог принадлежащий к роду Amphioctopus marginatus.The coconut octopus belongs to the genus Amphioctopus marginatus.

Кокосовые осьминоги — это бентосные (обитающие на дне) животные из семейства обыкновенных осьминогов (Octopodidae). Они обитают в водах Индо-Тихоокеанской области на мелководье и на глубинах до 190 метров.Основная часть осьминога (туловище), как правило, около 8 см, и с щупальцами, около 15 сантиметров в длину.  Рисунок на их теле напоминает прожилки или вены, откуда пошло второе английское название осьминог с жилками. Руки обычно окрашены темнее и контрастируют с ярко-белыми присосками, которые способными отражать свет, из-за чего ошибочно кажутся  флуоресцирующими.

Кокосовые осьминоги обычно охотятся на креветок, крабов, моллюсков и проявляют необычное поведение, такое как двуногая ходьба и использование скорлупы кокосового ореха или ракушки для жилья. Иногда кокосовые осьминоги прячутся в пластиковых стаканчиках, стеклянных и жестяных бутылках, мыльницах и другом мусоре. А иногда — в раковинах брюхоногих моллюсков. Кокосовый осьминог умеет менять свой окрас в зависимости от настроения. Это происходит благодаря множеству красящих пигментов в организме. Под влиянием импульсов, исходящих от нервной системы, в обычном состоянии осьминог имеет коричневатый оттенок, в злом – красный, а когда он испуган – белый.

Coconut octopuses are benthic (bottom-dwelling) animals from the family of common octopuses (Octopodidae). They live in the waters of the Indo-Pacific region in shallow waters and at depths of up to 190 meters. The main part of the octopus (torso) is usually about 8 cm, and with tentacles, about 15 centimeters in length. The pattern on their body resembles veins or veins, hence the second English name veined octopus. The arms are usually darker colored and contrast with the bright white suckers, which are capable of reflecting light, causing them to mistakenly appear to be fluorescent. Coconut octopuses typically hunt shrimp, crabs, shellfish, and exhibit unusual behaviors such as bipedal walking and using coconut shells or shells for shelter. Sometimes coconut octopuses hide in plastic cups, glass and tin bottles, soap dishes and other garbage. And sometimes in the shells of gastropods. The coconut octopus can change its color depending on its mood. This occurs due to the many coloring pigments in the body. Under the influence of impulses emanating from the nervous system, in its normal state the octopus has a brownish tint, when angry it is red, and when it is scared it is white.

Home on the Road: This Octopus Just Loves Life in a Shell

Is this the original RVer? The veined or “coconut” octopus’s home is wherever it puts down its, well, shell. And we’re glad to announce there’s one parked in our Tentacles exhibit right now.

But it’s not just a coconut shell that this cephalopod settles down in. Our Curator of Husbandry Operations, Paul Clarkson, says that the veined octopus (Amphioctopus marginatus) will “pick up anything at its disposal” to make a home on the road. This includes old cans, bottles, boots, shells and yes—coconuts. In fact, it’s proud to take up residence in any recently foreclosed property on the ocean floor. It’s all home as far as this cephalopod is concerned.

It could just be the ultimate recycler.

Octopus odyssey

Paul was recently part of a trip to the Philippines,  and his sole goal was to collect this curious cephalopod. The trip was organized by the California Academy of Sciences, which also happens to be the only other aquarium in the U.S. to have displayed them.

The dive site was near an old pier, which—unfortunately for the ocean, but perhaps not so much for the octopus—was rife with trash. He said they would often find the animals closed up in clam shells, with just their eyes poking out, surveying the scene. If spooked, Paul said, the octopus would “just duck down and close up the shell.” To move, it would pick up the shell and just hit the road.

This made life easy for the scientists on the trip. “To collect these octopuses, we would just take the whole house, with the animal inside. It was good for them, and easy for us.” The shell also furnished first-class accommodations on the flight to California.

Paul found that, if he was patient, the octopuses were quite sociable. “If we just sat still, with a crab or other prey, they would come right over and eat out of our hands.”

About the veined octopus

The veined octopus is found in Indo-Pacific waters, has a fist-sized body and lives to be a year old. Common prey items include crustaceans and small fishes.  

You can find it in our Tentacles exhibit, in the spot formerly occupied by the two-spot octopus, which has been moved behind the scenes. Don’t be surprised to find this vagabond displayed with some of the junk that commonly forms its home in the wild.
