• Scaly Jewfish
• Silver Jewfish
• Teraglin

Origin of jewfish

The precise origin of jewfish is not known, however, it has been traced back as early as the 8th century. The Christian Bible offers an account of a fish that swallowed the prophet Jonah whole. Nonetheless, The Bible did not specify the exact kind of fish. As the this is so big, many believed it was responsible for the act. William Dampier, an English tourist who traveled around the world three times, wrote about this fish in his 1697 book, A New Voyage Around The World. 

Dampier described this fish as the perfect fish and wrote that the English likely give it that name because it has scales and fins. He also wrote that the it was a kosher creature adored by Jewish people in Jamaica. In 2001, a team of scientists successfully appealed to have the name “Jewfish” changed to “Goliath Grouper” because they felt the original name was being used abusively.
