Spinachia
Spinachia is a genus of fish in the Gasterosteidae family. It contains only one species, the Sea Stickleback, also known as Fifteen-spined or Fifteenspine stickleback, (Spinachia spinachia), which lives in benthopelagic and in brackish environments of the northeastern Atlantic Ocean.
Although it is the largest form of stickleback, the Sea Stickleback is a small fish, reaching a maximum length of 22 cm. It is of no commercial interest in fishing.Sticklebacks are distinguished by the presence of strong and clearly isolated spines in the dorsal fin. Their maximum length is about 4 inches, but few of them are more than 3 inches long. They mature sexually at a length of about 2 inches.All species show a similar mating behaviour, which is also unusual among fish. The males construct a nest from vegetation held together by secretions from their kidneys. The males then attract females to the nest. The female will lay their eggs inside the nest where the male can fertilise them. The male then guards the eggs until they hatch.
