Habitat & Geographic Range
Common Elephant Tusk
Native to Europe, inhabiting ecosystems characteristic of the region.
Distributed across Denmark, Norway, and Sweden.
Common Starling
Found across multiple habitat types including temperate broadleaf and mixed forests, tundra, and tropical and subtropical grasslands and savannas, among 9 distinct biome types. Populations are also found in montane and highland environments at higher elevations.
Widely distributed across Africa (4 countries), Europe (5 countries), North America (6 countries), Oceania and the Pacific (Australia, New Zealand, Tonga), and South America (Argentina, Bolivia, Uruguay). Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.
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 Starling
Common Starling (Sturnus vulgaris) is classified as Near Threatened (NT) on the IUCN Red List. Close to qualifying as threatened, with populations that may become vulnerable without conservation action.
