Climbing Star-apple

Climbing Star Apple, Landolphia species, is a genus of woody, climbing lianas and scrambling shrubs in the family Apocynaceae native to tropical and subtropical Africa. Landolphia species were historically important as sources of wild rubber; the latex from cut stems and roots was a major commercial rubber source in central Africa before Hevea brasiliensis became dominant, and its exploitation under Belgian colonial rule in the Congo Free State caused widespread human rights abuses in the late 19th century. The common name 'star apple' relates to the edible fruits produced by several species, which are large, yellow or greenish, with a sweet pulp surrounding the seeds. The fragrant flowers are white and produced in terminal clusters, pollinated by insects. Landolphia species grow in tropical forest margins, secondary forest, and gallery forest across sub-Saharan Africa, where they play an important role in forest structure by connecting canopy layers. The edible fruits are consumed by wildlife and by local human communities. Several Landolphia species are used in traditional medicine for treating a variety of ailments. Conservation status varies among species; some with restricted ranges in heavily deforested areas face threat from habitat loss.

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.
