in some classifications: a class of vertebrates comprising all the fishes and sometimes the cyclostomes and lancelets
(Latin: Fishes) In astronomy, the constellation lying between Aries and Aquarius; in astrology, the twelfth sign of the zodiac, governing approximately the period February 19–March 20. Its symbol is two fish tied together. These are a reference to the Greek myth of Aphrodite and Eros, who jumped into a river to escape the monster Typhon and were changed into fish. In another version of the myth, two fish carried them to safety.
