Distributed across Denmark, Norway, and Sweden.

Chocolateweed

Chocolateweed (Melochia corchorifolia) is a pantropical annual or short-lived perennial herb in the family Malvaceae, widespread across tropical and subtropical Asia, Africa, the Pacific islands, and Australia. It is a common weed of disturbed and agricultural habitats including rice paddies, riverbanks, roadsides, and field margins, tolerating a wide range of soil types including waterlogged and saline conditions. The plant grows to 40–100 centimetres, producing alternate, toothed leaves and small pink to purplish flowers followed by rounded, ribbed capsule fruits. The stem fibres of Melochia corchorifolia are used traditionally in parts of Asia and Africa as a substitute for jute in making rope, matting, and rough textiles, reflecting the plant's membership in the mallow family which includes many fibre-producing species. The seeds and young leaves are edible in some cultures and the plant has uses in traditional medicine. Despite its status as an agricultural weed, it also provides nectar for bees and other insects. The IUCN classifies it as Least Concern, reflecting its widespread and abundant distribution across tropical agricultural landscapes worldwide. Its success as a coloniser of disturbed habitats suggests high resilience to anthropogenic change.

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.
