Corpul este divizat în trei regiuni: trompă, trunchi și apendici caudali. În partea anterioară a corpului se află trompa (proboscis, introvert sau capul) exertilă, capabilă să se invaginize în interiorul corpului. Pe suprafața trompei se găsesc șiruri longitudinale de țepi recurbați.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> Trunchiul (abdomenul) este acoperit cu o <a href="/wiki/Cuticul%C4%83" title="Cuticulă">cuticulă</a> <a href="/wiki/Chitin%C4%83" title="Chitină">chitinizată</a>, poate fi neted sau să prezinte inelații, uneori este prevăzută cu spini (această nu reprezintă o segmentare adevărată a corpului ca la viermii inelați).

Cavitatea corpului reprezintă un <a href="/w/index.php?title=Celom&action=edit&redlink=1" class="new" title="Celom — pagină inexistentă">pseudocelom</a> (sau hemocel) cu o membrană acelulară. </p><p><b>Sistemul nervos</b> este format dintr-un inel perifaringian, cordon nervos ventral de la care pornesc nervi longitudinali și transversali, și un ganglion nervos posterior. În etapa dezvoltării embrionare, sistemul nervos rămâne în ectoderm, fără ca să se separe, ulterior făcând parte din peretele corpului. <i>Organele de simți</i> sunt slab dezvoltate, reprezentate de papile senzitive amplasate preponderent în regiunea trompei. </p><p><b>Aparatele circulator</b> și <b>respirator </b>sunt absente.

Filtrarea metaboliților se produce în protonefreiii ramificate care conține solenocite - celule flagelate. Protonefridiile sunt amplasate de-a lungul canalului urogenital. Glandele sexuale, testiculele și ovarele, sunt perechi atașate de pereții corpului prin mezenter. Glandele sexuale sunt alcătuite din diverticule închise la un capăt și se deschid cu celălalt capăt în canalul urogenital.

Fecundația este externă, însă la unele speciile se se pare că există o fecundație internă. Segmentarea ovulelor fecundate este uniformă și radiară. Dezvoltare are loc lent, prima diviziune a ovulelor se atestă la 15 ore după fecundare, <a href="/w/index.php?title=Gastrulare&action=edit&redlink=1" class="new" title="Gastrulare — pagină inexistentă">gastrulația</a> - în câteva zile, iar eclozarea larvelor - în 15-20 zile. Din ou se dezvoltă larvă care se aseamănă foarte mult cu adultul. Cuticula larvei este groasă și puternic chitinizată, formând o lorică, alcătuită din două valve ce conferă corpului formă aplatizată. Metamorfoza larvelor are loc prin câteva năpârliri, lorica fiind eliminată.
