Kashrut
Among the numerous laws that form "kashrut" are prohibitions on the consumption of certain animals (such as pork and shellfish), mixtures of meat and milk, and the commandment to slaughter mammals and birds according to a process known as "shechita". There are also laws regarding agricultural produce that might impact the suitability of food for consumption.
Oarfish
From December 2009 to March 2010, unusual numbers of the slender oarfish "Regalecus russelii" (宮の使い “Ryūgū-No-Tsukai”,) known in Japanese folklore as the "Messenger from the Sea God's Palace", appeared in the waters and on the beaches of Japan, the appearance of which is said to portend earthquakes.
Oarfish feed primarily on zooplankton, selectively straining tiny euphausiids, shrimp, and other crustaceans from the water. Small fish, jellyfish, and squid are also taken. Large open-ocean carnivores are all likely predators of oarfish.
