Gastropods are the second largest class of animals (after the Insecta)—with 40,000–90,000 living species and at least 13,000 extant and fossil genera (Ponder and Lindberg, 2020)—and are also one of the most evolutionarily successful groups in the variety of ecosystems and habitats that they occupy.

Space Invaders is a 1980 video game based on Taito’s arcade game Space Invaders (1978) for the Atari 2600. It was developed and released by Atari, Inc. and designed and developed by Rick Maurer. The game is based on the arcade game in which a player operates a laser cannon to shoot at incoming enemies from outer space. Maurer’s version has unique graphics and offers some gameplay variations. These include a two-player mode and variations that allow for invisible enemies and moving shields, and for enemies shots to zig zag and potentially hit players.
