 It's July 18th, and this is your Fox Daily Snapshot. Today is National Caviar Day. Normally associated as a delicacy of the upper crust, caviar is the fish eggs of the sturgeon. The day is also meant to raise awareness to the survival and conservation of the species. The United States was once the leading distributor of caviar, exporting nearly 600 tons a year, until roughly 1900 when the practice was banned due to over-harvesting.
