Chrysanthemums on land bloom in autumn, but in the vast ocean, there are "sea chrysanthemums" that bloom all year round. They are sea anemones. Sea anemones come in many shapes, with thousands of species, generally cylindrical in shape, with bright colors, and their bases attached to rocks, shells, gravel or the seabed. The upper end of the sea anemone is a round disk, surrounded by several to thousands of chrysanthemum petal-like tentacles. They sway with the waves in the water, opening and closing like flowers. The large anemone that lives on the reef has sky blue and yellow tentacles that form a bright "flower bush". Fish and shrimps compete to play in the "flower bush". Once the stinging cells in its tentacles are If stabbed, it will be paralyzed, and finally it will be rolled into the mouth by the tentacles and become its delicious meal. Only the brightly colored clownfish can live with it for mutual benefit. Some biologists believe that the lifespan of sea anemones is as long as 300 years, so this "sea chrysanthemum" can bloom for 300 years without fading, which is incomparable to terrestrial chrysanthemums.
