TL;DR: Polychaetes are common in most marine habitats and dominate many infaunal communities and now include osmotrophic siboglinids as well as sipunculans, echiurans, and myzostomes, which molecular genetic analyses have placed within Annelida.

TL;DR: The sources and the frequencies of injury in a variety of marine invertebrates from different benthic habitats are reviewed, challenges, and approaches for accurately determining injury rates in the field are discussed, and evidence for species-specific, temporal and geographic variation in injury rates is considered.

TL;DR: The ease of identifying responsive day 4 fish suggests these animals may be useful for characterizing odorant sensitivity or developmental plasticity or for screening for chemosensory mutations.

TL;DR: The most biologically and geochemically active marine sediments are characterized by steep chemical gradients within the top centimeters of sediment (Berner, 1980) as discussed by the authors, which may be a cue used by juveniles to distinguish between recently disturbed and undisturbed surfaces.

TL;DR: Results were consistent with the hypothesis that new juveniles reject (or are significantly slower to burrow into) disturbed sediment surfaces, if the disturbance is less than several hours old, and imply that the new juveniles are utilizing cues associated with a process, the disturbance of surface sediments, in addition to the species-specific cues described elsewhere.
