Nature: The Stickleback Fish

The male stickleback’s abdomen turns red at the start of the breeding season in spring. Usually the abdomen of this small fish is silver coloured, the rest of it differing from brown to green. But when the time comes for him to mate he becomes very active in enticing females with his bright new colour.

In building the home and nurturing the family the male stickleback accomplishes many of the functions usually associated with a female fish. He selects the place for the nest, gathers the stems of various aquatic plants and ties them together using a threadlike web excreted from his kidney.

Once the female has been allured into his nest, she will lay her eggs and leave, departing him on guard. He watches over the eggs with great custody and even looks after the baby fish.
