Sticklebacks
Change in Males during Spawning Time
More than fifty fish species live in our lakes and rivers. The sticklebacks count among the smallest native freshwater fish. The three-spined stickleback is of an inconspicuous colour almost all year long. But during the spawning season, something extraordinary happens: the body colour and behaviour of the males change. Therefore, this small and ordinary fish attracted the attention of behavioural scientists early on.

They are short notes, long texts, pictures, videos, which are posted loosely and at random intervals to the world for an undefined public.
