| 描述 海百合是一種始見於奧陶紀的棘皮動物，生活於海裏，具多條腕足，身體呈花狀，表面有石灰質的殼。海百合具有形如植物的外形，及變化多端的顏色，有如一朵朵在海底綻放的彩色煙火。由於牠們的外形有如羊齒植物或百合花，因此有”海羊齒”及”海百合的稱號。 海百合綱動物與其他棘皮動物最大的不同是牠們的口是朝上的，利用羽毛狀的腕及”羽枝”捕捉海水中的有機顆粒及浮游生物，再由腕中央的步帶溝將食物顆粒送至口中。 這大型海百合莖化石標本長約5厘米-7厘米，直徑約1.5厘米，在標本上仍可以看到節段。 請注意，這些標本取自30年前的舊庫存。 | Description Crinoids are marine animals that make up the class Crinoidea, one of the classes of the phylum Echinodermata, which are also called the lily of the sea.
