白天的星星(Stars in daylight)

海星——通常仍被称为海星——是生活在我们海洋中最迷人的生物之一。首先，尽管它们有名字，但它们不是鱼。它们属于一种叫做棘皮动物的海洋无脊椎动物。海星的特征是它们的身体径向对称，通常有多个从中心圆盘延伸的“臂”。

Sea stars - still often called starfish - are one of the most fascinating creatures to live in our oceans. For starters, despite their name, they aren’t fish. They belong to a group of marine invertebrates called echinoderms. Sea stars are characterised by the radial symmetry of their bodies, which usually have multiple 'arms' extending from the central disc.
