Eater 1 (or fishhook or simply eater) was the first discovered eater. Its ability to eat various objects was discovered by Bill Gosper in 1971. It is the smallest still life that is neither radially symmetric nor symmetric through a line, and it is the thirteenth most common still life, being less common than mango but more common than long barge.
It only takes four generations to recover from being hit by a glider, making it the fastestrecovering glider eater, and it is also the smallest glider eater. As such, it appears as a stabilizer at the corner of dozens of oscillators including Jason's p22, buckaroo, p54 shuttle, pentoad, p47 prepulsar shuttle, and snacker.
