Scaphopoda is a class of marine molluscs commonly known as elephant tusk shells because of their long, curved, tusk-like shells. These small creatures live on the ocean floor and are notable for being a distinct group within the diverse mollusc family, which includes animals like clams, snails, and squid.

掘足纲是软体动物门的一个纲。全部是海产泥沙中穴居的一类小型软体动物，仅有350种左右。海生，直至7000米可见其踪迹。 贝壳长，似象牙，管狀，成细弯刀型，两端开口。体长达14厘米。触手从下端开口伸出，不断开挖沉积物将身体大部分埋藏于沉积物中。通过触手将蓝藻，碎石等物质送到口部。上端开口保持其与外界接触。 有重力感觉器，无眼，但触手部分有感觉细胞。 目前仍不能肯定，它们是否具有心脏及心包膜。

Encyclopedic overview
Scaphopoda (/skəˈfɒpədə/; from Ancient Greek σκᾰ́φης (skáphēs) 'boat' and πούς (poús) 'foot') is a class of shelled marine molluscs (invertebrates within the phylum Mollusca), whose members are known as scaphopods (/ˈskæfəˌpɒdz/) and commonly called tusk shells or tooth shells. They have a worldwide distribution and are the only class of exclusively infaunal marine molluscs. Shells of species within this class range in length 0.5–18 cm (0.20–7.09 in), with Fissidentalium metivieri being the longest. Members of the order Dentaliida tend to be larger than those of the order Gadilida.
These molluscs live in soft substrates offshore (usually not intertidally). Because of this subtidal habitat and the small size of most species, many beachcombers are unfamiliar with them; their shells are not as common or as easily visible in the beach drift as the shells of sea snails and clams.
