Fish have a lot of amazing adaptations to allow them to live in the aquatic environment. Many of them are great swimmers. Most can successfully defend themselves against predators. Others have a fantastic camouflage ability. Still others, in order to protect their future offspring, place their eggs in a breeding bag on the male’s stomach. And did you know that some species of fish can change sex? We will tell you about the interesting things about fish from the seas and oceans, rivers and lakes. In the laboratory we will perform an ichthyological analysis of the herring. We will use the preparation tools. During the course participants complete the educational materials.
