Features: The sea, year after year, day after day, with its ebb and flow of tides, has nurtured a dazzling array of bizarre marine creatures. The coast is the only part of the ocean they know, and it marks the beginning of their friendship with the sea. Jellyfish living in the intertidal zone have stems, sea urchins are covered in sharp spines, anemones arm themselves with stinging cells, and sponges can launch chemical warfare against enemies by releasing toxins. The resilient coastal fish have large heads, small bodies, and gradually tapering tails. The gentle and docile sea butterflies wear proud "white hats" on their heads. Come with us and experience the vibrant coastal world!
