| Abstract | Members of the following marine annelid families are found almost exclusively in the
interstitial environment and are highly adapted to move between sand grains, relying mostly on
ciliary locomotion: Apharyngtidae n. fam., Dinophilidae, Diurodrilidae, Nerillidae,
Lobatocerebridae, Parergodrilidae, Polygordiidae, Protodrilidae, Protodriloididae, Psammodrilidae
and Saccocirridae. This article provides a review of the evolution, systematics, and diversity of these
families, with the exception of Parergodrilidae, which was detailed in the review of Orbiniida by
Meca, Zhadan, and Struck within this Special Issue. While several of the discussed families have
previously only been known by a few described species, recent surveys inclusive of molecular
approaches have increased the number of species, showing that all of the aforementioned families
exhibit a high degree of cryptic diversity shadowed by a limited number of recognizable
morphological traits. This is a challenge for studies of the evolution, taxonomy, and diversity of
interstitial families as well as for their identification and incorporation into ecological surveys. By
compiling a comprehensive and updated review on these interstitial families, we hope to promote
new studies on their intriguing evolutionary histories, adapted life forms and high and hidden
diversity. |
