The Baltic Sea, a young sea at around 10,000-12,000 years old, hosts unique marine life, including blåstång (bladderwrack) with its distinctive reproductive behaviors. According to illustrator, biologist, and author Erik Kohlström, the sea is 'jättekonstigt' (very strange), and his new book aims to inspire interest in underwater life rather than focus on environmental problems. Blåstång, an algae not a plant, reproduces with sperm and eggs, producing small algae babies sensitive to light and dark, while other species like tångräkor (shrimp) change sex and tångsnällan have males that carry pregnancies.
