舌形贝
延续数亿年的古老腕足动物
舌形贝又称海豆芽，是一类演化历史
悠久的腕足动物，外形具有类似贝壳的
两片壳体，但与双壳类动物亲缘关系较
远。它们通常利用肉质柄固着于海底，
通过带有纤毛的腕捕获水中的微小颗
粒进行滤食。舌形贝的化石记录可追溯
至古生代，是研究腕足动物长期演化稳
定性的重要代表。
Lingula
An Ancient Brachiopod Lineage Persisting for Hundreds of 
Millions of Years
Lingulid brachiopods, commonly known as “tongue shells,” 
are a group of brachiopods with a long evolutionary history. 
Although their shells resemble those of bivalves, they are 
only distantly related to true bivalve mollusks. They typically 
attach themselves to the seafloor using a fleshy pedicle and 
use ciliated lophophores to capture microscopic particles 
suspended in the water for filter feeding. The fossil record of 
lingulid brachiopods extends back to the Paleozoic, making 
them important representatives for understanding 
long-term evolutionary stability in brachiopods.
