Fo-ord tacsanomaíoch de seilidí mara peiligeacha beaga snámha is ea Thecosomata. Is moilisc ghastrapódacha holaplanctónach iad sa ghrúpa neamhfhoirmiúil Opisthobranchia. Ina measc, tá roinnt de na speiceas gastrapódach is flúirí atá sa saol.[1]
Chomh maith lena comhghrúpa, Gymnosomata, tá an grúpa seo san áireamh sna pteropoda. Níl bailíocht an chlád bunaithe go comhaontach; cé nach bhfuil gnaoi na n-eolaithe air ar feadh roinnt blianta, tugann fianaise mhóilíneach le déanaí le fios gur chóir an tacsón a athbheochan. .[2] Bíonn blaosc chailcithe ag formhór na Thecosomata cé nach bhfuil aibí Gymnosomata.
