n 1980, when some campus teams wanted more organized yet still low-key participation in extramural competition, UCSC joined Division III of the NCAA in five sports. The application required an official team name, and UCSC's chancellor at the time, Robert Sinsheimer, selected a new moniker: the sea lions.
While the chancellor considered sea lions more dignified and suitable to serious play than Banana Slugs, the new name did not find favor with the majority of students, who continued to root for the Slugs even after a sea lion was painted in the middle of the basketball floor.
After five years of dealing with the two-mascot problem, an overwhelming proslug straw vote by students in 1986 persuaded the chancellor to make the lowly but beloved Banana Slug UCSC's official mascot.
