From today's featured article

The queen angelfish (Holacanthus ciliaris) is a species of marine angelfish found in the western Atlantic Ocean. It is a warm-water species that lives near the ocean floor in coral reefs. It is blue and yellow and has a distinctive spot or "crown" on its forehead. This crown distinguishes it from the similar, closely related, Bermuda blue angelfish, with which it overlaps in range and can interbreed. Adult queen angelfish primarily eat sponges. They form harems of one male and up to four females. They live within a territory where the females forage separately and are tended to by the male. Breeding occurs near a full moon. The transparent eggs are pelagic and float in the water, hatching after 15 to 20 hours. Juveniles have different coloration than adults and act as cleaner fish. The queen angelfish is popular in the aquarium trade. In 2010, the fish was assessed as a least-concern species by the International Union for Conservation of Nature. (Full article...)

Today's featured picture

Hattie Wyatt Caraway (1878–1950) was an American politician who became the first woman elected to serve a full term as a United States senator, representing the state of Arkansas from 1931 to 1945. This photograph was taken in 1914, when her husband was a member of the United States House of Representatives. Although she took an interest in her husband's political career at the time, Caraway avoided the capital's social and political life as well as the campaign for women's suffrage, recalling: "After equal suffrage I just added voting to cooking and sewing and other household duties."
