The firefly squid, or Watasenia scintillans, is the only commonly edible bioluminescent creature in the world. In Japan, the species is famous for the light show it puts on along the coast when it spawns each spring. That's when the fishermen of Toyama Bay, in central Japan, go out in the dead of night to harvest the squid by the bucketful. The fruits of their labors end up salted, grilled, boiled, or served raw in restaurants around the country. You can learn more about the firefly squid, and their harvest, in the video from Great Big Story below:

The Truth Behind Italy's Abandoned 'Ghost Mansion'

The forests east of Lake Como, Italy, are home to a foreboding ruin. Some call it the Casa Delle Streghe (House of Witches), or the Red House, after the patches of rust-colored paint that still coat parts of the exterior. Its most common nickname, however, is the Ghost Mansion.

Since its construction in the 1850s, the mansion—officially known as the Villa De Vecchi—has reportedly been the site of a string of tragedies, including the murder of the family of the Italian count who built it, as well as the count's suicide. It's also said that everyone's favorite occultist, Aleister Crowley, visited in the 1920s, leading to a succession of satanic rituals and orgies. By the 1960s, the mansion was abandoned, and since then both nature and vandals have helped the house fall into dangerous decay. The only permanent residents are said to be a small army of ghosts, who especially love to play the mansion's piano at night—even though it's long since been smashed to bits.

The intrepid explorers of Atlas Obscura recently visited the mansion and interviewed Giuseppe Negri, whose grandfather and great-grandfather were gardeners there. See what he thinks of the legends, and the reality behind the mansion, in the video below.
