Collared Pratincole

The Collared Pratincole, known scientifically as <em>Glareola pratincola</em>, is a wading bird belonging to the family Glareolidae. <em>Glareola pratincola</em> is characterised by its distinctive pale throat patch bordered by a dark necklace or collar, giving the species its common name. The species is known for its swallow-like flight silhouette, with long, pointed wings and a forked tail, which it uses to pursue flying insects in aerial sorties over open habitats. It is reported to occur in Belgium, Denmark, Norway, Sweden, and Ukraine. Collared Pratincoles typically breed in open, dry habitats such as grasslands, mudflats, and steppe environments near water, and are often highly gregarious during the breeding season. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature.

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.
