Common Dodder

<em>Cuscuta gronovii</em>, the common dodder, is a parasitic annual vine in the family Convolvulaceae. This species is distributed across eleven European countries as well as the United States, where it typically inhabits diverse terrestrial environments including wetland margins, roadsides, thickets, and disturbed vegetation. Unlike most plants, <em>Cuscuta gronovii</em> lacks chlorophyll and is entirely dependent on host plants for water and nutrients, which it extracts through specialized structures called haustoria. The common dodder typically has slender, twining orange or yellowish stems and produces small, clustered white or pale pink flowers in late summer. It often parasitizes a broad range of host species, including many herbaceous and shrubby plants. Once attached to a host, it typically sheds its connection to the soil and relies entirely on the host for sustenance. The species is assessed as Least Concern, reflecting its wide distribution and ability to colonize disturbed habitats. Its parasitic life history makes it ecologically notable among flowering plants.

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.
