　　Fish Communication

　　The answer to both questions is yes, but fish "talk" and "hear" somewhat differently than humans. Although not extremely common, there are several species of fish that are able to produce sound to communicate with members of their own and other species. Most of the fish that produce sound do it at such low frequencies that divers cannot hear the noises. But several species do produce sound in the range that humans can hear. For example, grunts are able to produce sound by grinding their flat teeth together (hence the name grant!) The large Jewfish, Nassau and Black groupers are known to make very loud "booms" when startled or cornered. Jewfish have also been observed to make these loud sounds during courtship.

　　參考閱讀： The history of Ancient Greek coinage can be divided (along with most other Greek art forms) into four periods, the Archaic, the Classical, the Hellenistic and the Roman. The Archaic period extends from the introduction of coinage to the Greek world during the 7th century BC until the Persian Wars in about 480 BC. The Classical period then began, and lasted until the conquests of Alexander the Great in about 330 BC, which began the Hellenistic period, extending until the Roman absorption of the Greek world in the 1st century BC. The Greek cities continued to produce their own coins for several more centuries under Roman rule. The coins produced during this period are called Roman provincial coins or Greek Imperial Coins.
