Oyster
From Memory Alpha, the free Star Trek reference
Oyster is the common name of a number of different groups of bivalve mollusks native to the planet Earth, most of which live in marine habitats. The shell consists of two usually highly calcified valves which surround a soft body. The oysters known as "true oysters" are highly prized as food, both raw and cooked.
In 1893, a young Jack London mentioned to Data that among his wide spectrum of previous occupations he used to be an oyster pirate. Samuel Clemens, who later inspired London to take up writing, joked that even oysters probably required fifteen million years to "come out just right" when discussing the relative age of the Earth to the existence of Humankind.
