Abstract:
... We documented capture of microalgal prey by several species of wild‐caught Müller's larvae of polyclad flatworms. To our knowledge, this is the first direct observation of feeding mechanism in this classical larval type. High‐speed video recordings showed that virtually all captures were mediated by large‐scale transient ciliary reversal over one or more portions of the main ciliary band correspon ...

Abstract:
... To find out the effect of feed materials on the nutrient composition of Protaetia brevitarsis larvae (Pbl), three different feed materials were prepared and fed to the Pbl populations. After the Pbl population reached the third instar stage, they were boiled and dried for the nutrient analysis. The results showed that the nutrient composition of Pbl varied in response to the feed materials. Theref ...

Abstract:
... Within a week of fertilization, a zebrafish larva has developed a robust behavioral repertoire that includes the ability to learn about noncontingent stimuli. I begin this paper with a brief review of the t1-t2 framework in which groups receive different experiences at the first time point (t1) followed by a common assessment at the second time point (t2) and the strengths of this framework for st ...

Abstract:
... BACKGROUND: The apical organ is the most prominent neural structure in spiralian larvae. Although it has been thoroughly investigated in larvae of the class Pilidiophora in phylum Nemertea, studies on its structure in other nemertean larvae are limited. Most adult hoplonemertean worms have a frontal organ located in a position corresponding to that of the larval apical organ. The development and s ...

Abstract:
... The failure of depleted bivalve populations to recover naturally is often due to a breakdown in recruitment processes, such as a lack of larvae or suitable settlement substrate. The identification of these recruitment limitations are a critical initial step for determining an appropriate strategy for restoration. A lack of larval supply and settlement substrate have both been suggested as possible ...

Abstract:
... Targets of deep-sea mining commonly coincide with biodiversity hotspots, such as hydrothermal vents. The resilience of these ecosystems relies on larval dispersal, which may be directed by habitat-specific soundscapes. We urge for a global effort to implement soundscape as a conservation tool to assess anthropogenic disruption to deep-sea benthic ecosystems. ...
