The three-spined stickleback is a secondary intermediate host for the hermaphroditic parasite Schistocephalus solidus, a tapeworm of fish and fish-eating birds. The tapeworm passes into sticklebacks through its first intermediate hosts, cyclopoid copepods, when these are eaten by the fish.
The Icelandic threespine stickleback (Gasterosteus islandicus) is a freshwater fish, and one of the few vertebrate species endemic to Iceland. In some literature it is considered as a subspecies of G. aculeatus, [2] though several authorities offer it full species status. [3] [4] It was first described by French biologist Henri Émile Sauvage ...
Two subspecies of three-spined stickleback (Gasterosteus aculeatus) are endemic to southern California – the unarmored threespine stickleback (G. a. williamsoni) and the Santa Ana stickleback (G. a. santaeannae). [1] Steelhead (Onchorhynchus mykiss) in Maria Ygnacio Creek, Santa Barbara County, California.

The only exception is the far larger fifteen-spined stickleback (Spinachia spinachia), which can reach 22 cm (approx. 8.8 inches). [12] Body form varies with habitat: sticklebacks in shallow lakes have developed a deep body specialized to enable feeding on benthic invertebrates, whilst those in deep oligotrophic lakes have adapted to feed on ...
Prevalence — the proportion of host population infected — in naturally infected populations of the first intermediate hosts is likely low. [5] Conversely, in populations where Schistocephalus solidus infects the second intermediate host (three-spined stickleback) it can reach high prevalence, up to 93% in both European and North American populations [6] [7]
