Lobster is a c/7 diagonal spaceship that was discovered by Matthias Merzenich on August 19, 2011.[1] It was the first c/7 diagonal spaceship to be found. It consists of two gliders pulling a tagalong-like object that then rephases them. It can be infinitely extended.[2][3]

Lobster was voted Pattern of the Year for 2011 on the ConwayLife.com forums, tied with the fully universal Turing machine.[4]
