clusterleaf

Terminalia sericea, known as clusterleaf or silver terminalia, is a medium-sized deciduous tree in the family Combretaceae native to the savanna woodlands and bushveld of southern Africa, ranging from South Africa through Zimbabwe, Botswana, Namibia, and into Zambia and Mozambique. The species is a characteristic and abundant component of the broad-leaved miombo and mopane woodland systems of the region. Trees typically reach 6–12 meters in height, distinguished by their distinctive silvery-grey leaves clustered at branch tips, which account for the common name clusterleaf. The leaf undersides are covered with fine silky hairs giving a silver sheen that is particularly visible in sunlight and dry season conditions. Terminalia sericea is prized for its dense, durable hardwood, and extracts from the roots, bark, and leaves have extensive applications in traditional African medicine, being used to treat infections, stomach complaints, and malaria symptoms. Pharmacological research has confirmed antimicrobial and anti-inflammatory properties in the species. It produces small, winged fruits that are wind-dispersed across the savanna landscape. The species is assessed as Least Concern by the IUCN and remains common and widespread across its southern African range.

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.
