As a commonly available source of protein, octopus has been consumed as food in coastal areas worldwide. But now that it's been proved that there are several independent species of common octopus within the O. It is characterized by eight tentacles having multiple suckers. Until recently, the declining numbers caused little concern, as it was assumed that all common octopuses belong to a widely available global species. The Moroccan octopus fishery collapsed several years ago, while that off Mauritania continues to be heavily exploited. Independent art hand stretched around super. Imports of Octopus vulgaris have been masking the decline in O. High quality Japanese Octopus inspired canvas prints by independent artists and designers from around the world. Currently, the world's common octopuses are the most highly prized for their taste, and their popularity has contributed to employment in the fisheries and aquaculture industries.īut a steady fall in catches of common octopuses around the world is causing concern. It is high in protein and the healthy amino-acid taurine, while also low in fat and carbohydrates. The impact of this finding is significant because the growing popularity of octopus as food is putting intense pressure on marine resources. Modern DNA barcoding, too, can now distinguish clearly between the two species. Easily find the right translation for Octopus from English to Japanese submitted and enhanced by our users. But octopus eggs are something we’ve never seen on a restaurant menu in Japan, or even in a Japanese supermarket, until last week. sinensis males, which is used for mating, also has far fewer suckers than that on O. Octopus is a mainstay at sushi restaurants, and morsels of the sea creature are also at the core of takoyaki dumplings, one of Japan’s favorite snacks. It found that mature Japanese Octopus sinensis have a relatively broader head and shorter arms with about 80 fewer suckers per arm than the European Octopus vulgaris. The new study therefore set out to look for physical differences between the Japanese and European common octopuses. These features tend to make all octopus species look rather alike.
Octopuses get their name from their distinctive eight arms, and are known for their ability to rapidly change their colour and appearance. One of these is now recognized as Octopus sinensis, which is found throughout warm seas on the continental shelf of East Asia, including the main islands of Japan. The name Octopus vulgaris was first used for the European common octopus, which was long thought to be cosmopolitan, with similar-looking octopuses mistakenly identified in many countries - including Japan - as just one species distributed globally.īut recent research has shown that the so-called global Octopus vulgaris is actually a mixture of several distinct, though closely related, species. Madako, which means 'common octopus,' is a name well known in Japan and, for over a century, scientists have called it Octopus vulgaris.īut according to Ian Gleadall, a British researcher at Tohoku University's Graduate School of Agricultural Science, the Japanese common octopus is a different species, Octopus sinensis.
