It is a common sight in winter to see octopi hanging out to dry along sidewalks in the town of Toba (Mie prefecture), according to the caption for this image from the Toba Photo Gallery.

An octopus with nine tentacles was spotted at the Marusan Seafood Shop in Marugame, Japan (Kagawa prefecture) on October 26, one day after it was caught in the Seto Inland Sea. Masa Koita, the 60-year-old shop manager, noticed the abnormal Common Octopus (Octopus vulgaris) after he had boiled it in preparation for market. “In 40 years of handling seafood, I’ve never seen an octopus like this,” he said.
A spokesperson for the Akashi Seafood Council in nearby Hyogo prefecture confirmed the unusual nature of the extra-tentacled creature: “In Akashi, we might see one every 20 years or so. They are extremely rare.”
Koita says he will show off the octopus for a few days before selling it to a lucky customer.

This video clip from Japanese TV program “Best House 123″ shows the top three glow-in-the-dark sea creatures selected by Hokkaido University professor Yoshihiro Omiya, a specialist in the study of bioluminescent organisms.
3. Firefly squid: This blue-glowing squid, Japan’s most famous bioluminescent creature, measures 5 to 7 centimeters long and is often found at depths greater than 200 meters. In spring, when firefly squid rise to the surface to spawn en masse, they become Toyama’s great tourist attraction and end up on dinner plates nationwide. One reason the firefly squid glows is to hide itself from predatory fish swimming below. When the squid lights up its bottom surface, fish looking up have a hard time seeing it because it blends with the sky above.
2. Bioluminescent plankton: Measuring 0.1 centimeter long and found in oceans around the world, this type of dinoflagellate glows blue when disturbed. Professor Omiya keeps a flask of the light-emitting plankton in his fridge, because just looking at the cool blue glow helps him relax when he’s feeling stressed. While bioluminescent creatures are generally believed to emit light in order to intimidate their enemies, attract mates or defend themselves from predators, it is not entirely clear why this plankton glows.
1. Bioluminescent comb jelly: This 10 to 15 centimeter long gelatinous deep-sea creature, found at dark ocean depths of more than 200 meters, glows seven different colors in an otherworldly display of light. Many questions remain unanswered about why this comb jelly glows, making it a fantastic rainbow-colored mystery.
For the love of Cthulhu, here are photos of giant cement octopi posing as playground equipment in Japan.
UPDATE: Here’s a huge, wonderful photo gallery of octopus slides (Thanks, Alexander!). According to the site, there are no accurate records showing how many of these giant cement creatures exist in Japan, but they are believed to number in the hundreds. Many of these octopi, if not all, were constructed by Maeda Environmental Art Co., Ltd., who says each one has a unique design.
For more photos, check out this page by D-one, a photographer with an eye for the octopoid playscapes (the links that include pink text (タコ) are the ones you want to see). Also, a lot of the links on this page are to photos of octopus slides.
Most octopi squirt thick clouds of black ink to confuse predators. This video from a Japanese TV quiz show, however, shows a type of Tremoctopus, or blanket octopus (murasakidako in Japanese), employing a different technique. The video explains that when threatened, the octopus unfurls a giant sheet of webbing that trails behind like a cape. The webbing breaks apart rather easily when attacked — much like a lizard’s tail — and it gets wrapped around the predator’s face, giving the octopus a chance to flee.

Residents of the coastal town of Susami in Wakayama prefecture love the sea and the post office so much that the town once installed a mailbox on the ocean floor for scuba divers. Now, further evidence of this powerful sea/mail love comes in the form of “Surumail” — edible postcards made from squid.
Produced by the Susami fishing cooperative, Surumail postcards consist of dried surume squid (Todarodes pacificus), the local seafood specialty. The squid jerky is flattened and vacuum-packed into the shape of a postcard, and an adhesive label is included for the postage, delivery address and a short message.
The fishing cooperative has sold between 4,000 and 5,000 cards each year since they went on sale in 2000. According to the Surumail website, which touts the postcards as a cutting-edge medium of communication for the 21st century, many big-name companies — including Microsoft and IBM — have inquired about the cards. Surumail may play an instrumental role in saving the Japanese economy, the website claims.
The postcards cost 320 yen (under $3) each and are available at the Susami post office and JR Susami station, as well as through the Susami fishing cooperative. You can also order the postcards online, but it is unclear whether they ship outside Japan.
It would be great to send one of these from Susami’s underwater mailbox.

In squid-crazy Hakodate, squid fishing is big business, the local specialties include shio ramen (squid-topped ramen) and ikasomen (raw squid cut into the shape of somen noodles), the summer festivals have residents busting squid-like moves in a dance called ika-odori (a squirmy version of the traditional bon dance performed at summer festivals throughout Japan), and the city fish is the squid. It is therefore unlikely that anyone was surprised when, on July 18, a group of Hakodate residents made an official announcement regarding plans to create a giant robotic squid for the city.
The citizens’ group, called “Robot Festival in Hakodate,” aims to create a new symbol for Hakodate, one of the leading tourist destinations in Hokkaido — and what better symbol than a giant robotic version of the city’s favorite creature?
Members of the group include university professors specializing in robotic engineering, who will work to incorporate cutting-edge technology that will allow the robot to be controlled remotely via the Internet. Development will be led by Hitoshi Matsubara and Hidekatsu Yanagi, information architecture professors at the School of System Information Science at Future University-Hakodate (FUN). Matsubara will handle the robotics research and development, while Yanagi will handle design. Students from the university, along with Hakodate high school teachers and students and others in the local manufacturing industry, will contribute ideas in brainstorming sessions.
The group has chosen “light” as the design theme for the robot — a choice based on the night view from Mt. Hakodate, a popular local tourist attraction where visitors can marvel at the twinkling lights of the city and squid fishing boats offshore. In line with this theme, the entire body of squid robot will be covered in lights that blink as the robot moves. In addition, the robot will be equipped with a set of wireless receivers and will have its own homepage featuring a set of controls that allow remote users to move the robot’s tentacles and eyes.
The developers plan for the robot to stand 5 meters (16 feet) in height. After an intial 1.5-meter prototype is completed this November, work will begin on the larger final version, which the group aims to unveil in a parade at the Hakodate Port Festival in the summer of 2007.
Masao Fujii, chairman of the citizens’ group, says, “We hope to create a high-quality robot that attracts a lot of attention and makes people want to come to Hakodate.”
The total cost of the robot is expected to be somewhere in the 30 million yen range (US$250,000). The group hopes to cover much of that cost with membership fees, so they are now recruiting members.

Toyama Bay is the habitat of the world-famous glowing firefly squid, which surface in large numbers every spring in a phenomenon that has been designated a special natural monument. Peak firefly squid season means big catches for fishermen and brisk business for sightseeing boats that provide close-up views of the magical action.
Early in the morning, after 3 AM, sightseeing boats depart the Namerikawa fishing port (Namerikawa is also home to the world’s only museum dedicated to the firefly squid) in Toyama prefecture, making a short journey to fixed nets located about 1 to 2 km offshore. As the fishermen haul in their nets, the light emitted by the firefly squid causes the sea surface to glow a cobalt blue, evoking squeals of delight from the tourists.
Toyama Bay’s firefly squid fishing season opened on March 1 and is expected to continue until the end of June. Sightseeing boats are scheduled to run until May 7.
