World Octopus Day
World Octopus Day
Today, we celebrate a creature with three hearts and the uncanny ability to change color at will: the octopus. Octopuses are cephalopods, marine animals like squids and cuttlefish that have tentacles. Among their many species is the small and shy mototi octopus, pictured here. It was discovered in 1999 around Rapa Island in the South Pacific and is known for the "fake eyes" or ocelli—vibrant blue and yellow rings—between its eyes and arms. Found in the Indo-Pacific region, including Indonesia, Australia, and Okinawa in Japan, mototi octopuses are masters of disguise. They usually have a dull orange-cream-brown color but when alarmed, they can quickly shift to striking maroon with white stripes along their body and arms. Also known as poison ocellate octopuses, these cephalopods are highly venomous. But you don"t need to worry about running into one, because they tend to be shy and solitary, often hiding in crevices, shells, or man-made objects like bottles and cans.Desktop Version

Kochia, Hitachi, Ibaraki prefecture, Japan
This fiery tumbleweed is kochia, which transforms landscapes when it takes on hues of red, orange, and pink in the fall. In the spring and summer, this annual herb resembles a fluffy green ball. Native to parts of Europe and Asia, kochia, also known as "summer cypress," is now widespread throughout the world. But it has a special place in Japan"s Hitachi Seaside Park, seen in today"s image, where around 30,000–40,000 kochia bushes are planted each year. These ornamental plants create a surreal landscape for visitors to wander through and also hold significance in Japanese culture. Historically, they have been dried to create brooms. However, not all parts of the kochia are destined to sweep the Earth—some are used for food. The plant"s nuts, "tonburi," often called "field caviar," are a prized garnish.Desktop Version
