Common Rock Borer

<em>Hiatella rugosa</em>, the common rock borer, is a bivalve mollusk in the family Hiatellidae, order Adapedonta. It is distributed across the North Atlantic, with documented records from Denmark, Norway, Sweden, and the United States. The species is assessed as Least Concern on the IUCN Red List, suggesting stable populations across its range. Common rock borers typically inhabit rocky intertidal and subtidal zones, boring into soft substrates including sandstone, shale, chalk, and compacted sediment using mechanical abrasion from their shells. This boring behavior provides the species with protection from predation and wave disturbance. <em>Hiatella rugosa</em> is a suspension feeder, typically extracting phytoplankton and suspended organic particles from the water column through its siphons. The genus Hiatella is considered nearly cosmopolitan, with species occurring from polar to tropical seas. Rock borers are small bivalves, typically reaching only a few centimeters in shell length. They are common components of rocky shore communities and serve as prey for predatory snails, shorebirds, and small fish. Biological traits such as precise lifespan, body measurements, and diet composition remain poorly documented in quantitative ecological studies for this taxon specifically.

White-tipped Swift

White-tipped Swift (Aeronautes montivagus) is classified as Least Concern (LC) on the IUCN Red List. Widespread and abundant across its range, with stable populations and no immediate conservation concerns.
