Sticklebacks are endemic to the temperate zone [5] and are most commonly found in the ocean, but some can be found in fresh water. The freshwater taxa were trapped in Europe , Asia , and North America after the Ice Age 10,000–20,000 years ago, and have evolved features different from those of the marine species.
The tapeworm passes into sticklebacks through its first intermediate hosts, cyclopoid copepods, when these are eaten by the fish. The parasite matures into its third larval stage, the plerocercoid, in the abdomen of the stickleback. Infected sticklebacks are afterwards consumed by fish-eating birds, which serve as the tapeworm's definitive host.
