Common Baskettail

The common baskettail (<em>Epitheca cynosura</em>) is a dragonfly found across terrestrial and freshwater habitats of the United States. It is classified as Least Concern on the IUCN Red List, reflecting a stable and widespread population within its native range. <em>Epitheca cynosura</em> belongs to the family Corduliidae and is typically associated with ponds, lakes, marshes, and slow-moving streams, where its aquatic larvae develop. Adults are often observed patrolling over open water and forest edges in search of prey and mates. The species is named for the basket-like egg mass that females carry at the tip of their abdomen before depositing eggs in water. Males often form feeding swarms, particularly in the morning hours, where they capture small flying insects. 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.
