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.

Abstract	Abstract The sun coral Tubastraea coccinea Lesson, 1829 (Dendrophylliidae) is a widely distributed shallow‐water scleractinian that has extended its range to non‐native habitats in recent decades. With its rapid spread, this coral is now one of the main invasive species in Brazil. Its high invasive capability is related to opportunistic characteristics, including several reproductive strategies that have allowed it to disperse rapidly and widely. To better understand the reproductive biology of T. coccinea and aid in developing management strategies for invaded areas, we investigated aspects of its reproductive performance and life cycle, including the effects of colony size, seawater temperature and salinity, and lunar periodicity on offspring production and larval metamorphosis competence. A total of 18,139 offspring were released in different developmental stages, mainly from the larger colonies, which also produced larvae with longer competence periods. The main reproductive peak occurred during the First Quarter and New Moon phases and was highest in water temperatures around 26°C. Together, these results help to explain the rapid expansion of T. coccinea into non‐native habitats such as the Caribbean and southwestern Atlantic, and will inform actions of the recent Brazilian National Plan for the prevention, eradication, control, and monitoring of sun corals.

Abstract	Technological advances throughout different fields of research have enhanced our understanding of biodiversity, especially for meiofaunal organisms, which are notoriously difficult to study because of their small size. Scanning and transmission electron microscopy, together with confocal laser scanning microscopy, has increased the amount of external and internal morphological information, improving the quantity and quality of species descriptions, as well as deepening our understanding of the evolutionary adaptations of meiofauna. In ecology, the characterization of molecules such as stable isotopes and fatty acids have permitted us to infer trophic niches of meiofauna species, enhancing our understanding of their functional role in the ecosystem. In parallel, advances in DNA sequencing techniques have allowed us to quantify with much higher accuracy the phylogenetic position of meiofaunal species. We here review the main biodiversity shortfalls in the studies of meiofauna, discussing how such shortfalls could be addressed, especially by merging different approaches. Important steps towards such interdisciplinary approach are to promote data sharing, to explore new technologies that combine disciplines, and to base studies on a clear theoretical framework. Working at the interface between different disciplines imposes several challenges and will require creative approaches, but well-designed studies making use of different methodologies will quickly contribute to address the main biodiversity shortfalls in the study of meiofauna.

Abstract	Abstract Background Kinorhynch segmentation differs from the patterns found in Chordata, Arthropoda and Annelida which have coeloms and circulatory systems. Due to these differences and their obsolete status as ‘Aschelminthes’, the microscopic kinorhynchs are often not acknowledged as segmented bilaterians. Yet, morphological studies have shown a conserved segmental arrangement of ectodermal and mesodermal organ systems with spatial correspondence along the anterior-posterior axis. However, a few aberrant kinorhynch lineages present a worm-like body plan with thin cuticle and less distinct segmentation, and thus their study may aid to shed new light on the evolution of segmental patterns within Kinorhyncha. Results Here we found the nervous system in the aberrant Cateria styx and Franciscideres kalenesos to be clearly segmental, and similar to those of non-aberrant kinorhynchs; hereby not mirroring their otherwise aberrant and posteriorly shifted myoanatomy. In Zelinkaderes yong, however, the segmental arrangement of the nervous system is also shifted posteriorly and misaligned with respect to the cuticular segmentation. Conclusions The morphological disparity together with the distant phylogenetic positions of F. kalenesos, C. styx and Z. yong support a convergent origin of aberrant appearances and segmental mismatches within Kinorhyncha.

Abstract	High-throughput DNA sequencing studies allow rapid and widescale investigations into complex assemblages of organisms that would otherwise remain infeasible. Recently scientists have begun to apply metagenomic sequencing (sequencing of the complete pool of DNA from a sample) to investigate microscopic animal communities. Mitochondrial genomes are an important locus for such studies; however, current databases of complete mitochondrial genomes remain incomplete, and many important meiofaunal clades are underrepresented or missing entirely. This underrepresentation is likely due to the low amount of input DNA acquired from meiofaunal individuals, the impossibility of pooling animals because of high levels of cryptic speciation, and the paucity of researchers collecting and studying these animals. Here we help to alleviate the first two barriers by developing a method of enriching animal mtDNA from next-generation sequencing libraries by using hybridization capture probes. These hybrid-capture probes were designed based on the complete collection of mitochondrial genomes available from GenBank and are suitable for enrichment of diverse animal lineages. We demonstrate the protocol on forty-seven meiofaunal specimens spanning four different phyla. Overall, we observed an average of ~450× fold enrichment over standard NGS sequencing library preparation. In addition, we were able to enrich the mtDNA from taxa distantly related to those in the database, indicating that even animals that were not directly targeted by the probe design can be enriched with this method.

Abstract	We present a species list of echinoderms from Araçá Bay, state of São Paulo. Altogether, 863 specimens belonging to 25 species, 19 genera, and 13 families were exhaustively collected during three years in consolidated and non-consolidated substrate. Ophiuroidea was the most representative taxon with 16 species, follow by Asteroidea with four species, Echinoidea with three, and Holothuroidea with two species. The brittle stars Amphiura kinbergi and Ophiothela cf. mirabilis are new records for Araçá Bay. We confirm that Araçá Bay is one of the best known area of echinoderm diversity in Brazil considering that the perimeter (3 km) of the bay corresponds to only 0.03% of the Brazilian coastline (8500 km). This work complements the knowledge of Araçá Bay biodiversity and supports future interventions, management and maintaining the diversity of this wonderful group of marine animals.

Abstract	This study focuses on a small-scale fishing community which primarily exploits fish in Tijucas Bay (Santa Catarina State, Brazil). The region is near a marine protected area and is also exploited by the industrial fishing fleet and shrimp fishers, however there is a lack of baseline and monitoring data about fisheries. We aimed to understand aspects of the historical dynamics of catches exploited by small-scale fishers and investigate their causes, through local ecological knowledge. We focused on four main target species: Genidens barbus, Micropogonias furnieri, Macrodon ancylodon and Mugil liza, which are the most important species targeted by fishing communities in the study area. We used face-to-face individual interviews with 34 fishers to identify changes in the current and past catches based on fishers perceptions. The current catches were smaller than the best previous catches for all species, suggesting a decline in catches. The perceived causes for the decline in catches were the industrial fishing, the shrimp trawling bycatch, and the overall increase in fishing effort. Fishers’ knowledge has proved to be an important complementary tool in the monitoring of catches. Management actions are needed to overcome this trend in declining local fish catches and to ensure the livelihoods of small-scale fishers.

Abstract	Aquaporins (AQPs) are a family of membrane channels facilitating diffusion of water and small solutes into and out of cells. Despite their biological relevance in osmoregulation and ubiquitous distribution throughout metazoans, the presence of AQPs in annelids has been poorly investigated. Here, we searched and annotated Aqp sequences in public genomes and transcriptomes of annelids, inferred their evolutionary relationships through phylogenetic analyses and discussed their putative physiological relevance. We identified a total of 401 Aqp sequences in 27 annelid species, including 367 sequences previously unrecognized as Aqps . Similar to vertebrates, phylogenetic tree reconstructions clustered these annelid Aqps in four clades: AQP1-like, AQP3-like, AQP8-like and AQP11-like. We found no clear indication of the existence of paralogs exclusive to annelids; however, several gene duplications seem to have occurred in the ancestors of some Sedentaria annelid families, mainly in the AQP1-like clade. Three of the six Aqps annotated in Alitta succinea , an estuarine annelid showing high salinity tolerance, were validated by RT-PCR sequencing, and their similarity to human AQPs was investigated at the level of “key” conserved residues and predicted three-dimensional structure. Our results suggest a diversification of the structures and functions of AQPs in Annelida comparable to that observed in other taxa.

Abstract	Abstract Extreme physical conditions usually limit the meiofauna occurrence and distribution in highly hydrodynamic environments such as reflective beaches. Despite sediment grains of the upper layers being constantly resuspended and deposited, the high energy of the swash zone besides depositing coarse sediments allows an ample vertical distribution of meiofaunal organisms. The effect of physical, chemical and sediment variables on the vertical distribution of meiofaunal organims and nematodes was analysed on two reflective exposed beaches. Sampling was conducted at three sampling points on each beach in the swash zone. The sediment collected was divided into four 10-cm strata (0-10 cm, 10-20 cm, 20-30 cm, 30-40 cm). The statistical differences between strata due to factors previously established (i.e. meiofaunal composition, density of most abundant taxa) were tested using a hierarchical PERMANOVA applied under similarity and euclidian distances. An inverse relation among average grain size, content of organic matter and sediment sorting was evident. Coarser sediment characterized the upper layers, while at deeper layers the sediment was very poorly sorted and presented a higher content of organic matter. A similar pattern in the vertical distribution of meiofaunal and nematofaunal composition and density was detected. The lowest densities were associated with the first stratum (0-10 cm), highly affected by hydrodynamics. The vertical distribution of organisms was statistically different only when the interaction among factors was considered. This result suggests that zonation and vertical distribution of meiofaunal organisms are determined by the within-beach variability.

Abstract	The sibling species of Capitella capitata are globally known for their tolerance to disturbed habitats and the C. capitata complex is often used as an ecological indicator. A recent re-description proposed that C. capitata, originally described in Greenland is restricted to the Artic and Subarctic regions. Given their ecological relevance, we conducted a morphological and molecular analyses based on mtDNA sequences to investigate the diversity and distribution of the C. capitata complex along the Brazilian coast. Our morphological and molecular data were congruent and revealed the existence of four new species distinct from C. capitata, collected from the type locality. This study is the first characterization of the biodiversity and distribution of Capitella species made along the Brazilian coast and yielded a set of morphological characters corroborated by the mtDNA sequences for species identification. Our results increase the biodiversity of the genus along the Brazilian coast by describing four new species (Capitella aracaensis sp. n., Capitella biota sp. n., Capitella neoaciculata sp. n. and Capitella nonatoi sp. n.). One species was collected from only one sampling site, while the others are distributed along the coast.
