Common Elephant Tusk

<em>Antalis entalis</em>, the common elephant tusk, is a marine mollusc in the class Scaphopoda, family Dentaliidae, classified as Least Concern by the IUCN Red List. The species is native to European waters and has been documented in Denmark, Norway, and Sweden, inhabiting subtidal and deep benthic zones of the northeastern Atlantic Ocean and North Sea. As a scaphopod, <em>Antalis entalis</em> is characterized by its distinctive curved, tusk-shaped shell that is open at both ends, allowing the animal to partially burrow vertically into sandy or muddy substrates with only the narrow posterior end projecting into the water column. The species feeds on foraminifera and other microscopic organisms in the sediment, capturing prey with specialized tentacle-like structures called captacula that extend through the broader anterior opening of the shell. Scaphopods have limited locomotion and typically remain partially buried throughout their lives. <em>Antalis entalis</em> plays a role in benthic communities as both a consumer of meiofauna and a prey item for predatory fish and invertebrates. Historically, elephant tusk shells of related species were used as currency and ornament by Indigenous peoples of the Pacific Northwest coast. Biological traits of this species remain poorly documented in the scientific literature.

Common Spruce Bell

<em>Epinotia tedella</em>, commonly known as the common spruce bell, is a small tortrix moth in the family Tortricidae, distributed across Europe wherever its primary host plant, <em>Picea abies</em> (Norway spruce), occurs. This species typically inhabits spruce forests, forest plantations, and woodland edges with significant spruce components, from lowland areas to montane elevations throughout much of the European continent. Its geographic range extends from Scandinavia and the British Isles south through central and eastern Europe, broadly following the distribution of its conifer hosts. Classified as Least Concern on the IUCN Red List, <em>Epinotia tedella</em> maintains stable populations across its range and is not considered threatened. The larvae feed internally within the needles of <em>Picea</em> species, mining leaf tissue and occasionally causing noticeable damage during outbreak years in plantation forestry. Adults are small moths with a wingspan of approximately 12–16 mm, displaying forewing patterns of brownish-grey with silvery strigulae typical of the genus. The species produces one generation per year, with adults flying from late spring to midsummer. Biological traits such as average lifespan in years, precise body weight, and detailed population dynamics remain poorly documented for this minor forestry pest. Diet consists primarily of Norway spruce needle tissue during the larval stage.
