common broomrape

The common broomrape (<em>Orobanche minor</em>) is a parasitic flowering plant with an exceptionally wide global distribution, occurring across Africa, Asia, Europe, North America, Oceania, and South America, and typically inhabiting tropical and subtropical forests and grasslands. This species is classified as Near Threatened on the IUCN Red List, indicating that its populations may be declining in some parts of its range. As a member of the family Orobanchaceae, the common broomrape is a root parasite that attaches to the roots of host plants, most commonly members of the legume and carrot families, from which it draws all of its nutrients. It lacks chlorophyll and therefore cannot photosynthesize, making it entirely dependent on its host for survival. The species often produces spikes of yellowish or purplish tubular flowers above the soil surface during spring and summer across its diverse geographic range. Biological traits of this species remain poorly documented in the scientific 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.
