Bluefin tuna is the common name for three of the eight species of tuna in the Thunnus genus (family Scombridae): the Pacific bluefin tuna (Thunnus orientalis), the northern bluefin tuna or Atlantic bluefin tuna (T. thynnus), and the southern bluefin tuna (T. maccoyii). They share with other tuna such characteristics as two dorsal fins that are depressible into grooves, finlets behind the second dorsal fin, pelvic fins with six rays placed behind the pectoral fins, a deeply forked tail, and a body that is very narrow right before the tail. These highly migratory, large, pelagic fish are fast swimmers and have a heat exchange system that allows them to elevate their body temperature well above ambient water temperatures; they can tolerate a very broad range of temperatures and inhabit a broad thermal niche.

Pacific bluefin tuna are found in both the western and eastern Pacific Ocean, largely in temperate waters in the North Pacific but their range also includes tropical waters in the southern hemisphere. Bluefin tuna are important both ecologically and commercially, as well as a popular target for sportsfishing. The bluefin tuna of all three species—northern, southern, and Pacific—are overfished throughout the world.
Thomas Jefferson (April 13, 1743 – July 4, 1826) was the third President of the United States (1801–1809), principal author of the Declaration of Independence (1776), and an influential Founding Father of the United States. Major events during his presidency include the Louisiana Purchase (1803), the Embargo Act of 1807, and the Lewis and Clark Expedition (1804–1806). Jefferson served as the second Governor of Virginia (1779–1781), the first United States Secretary of State (1789–1793), and the second Vice President (1797–1801).
In addition to his political career, Jefferson was an agriculturalist, horticulturist, architect, etymologist, archaeologist, mathematician, cryptographer, surveyor, paleontologist, author, lawyer, inventor, violinist, and the founder of the University of Virginia. Many people consider Jefferson to be among the most brilliant men ever to occupy the Presidency.
Jefferson had a strong commitment to religious freedom and in 1779 he authored the Virginia statute for religious freedom. He considered this as one of his three great life achievements along with drafting the Declaration of Independence and founding of the University of Virginia.
