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.

Original soundtrack Thissen: “It’s exactly the great flexibility of tablets that promotes very personalised and adapted learning.” Original soundtrack Welzel: “It’s fascinating to see how the children grow with their products and how they always want to improve them.” The Westminster Abbey is a church in London for the royal family.
