Chilean Dolphin

The Chilean Dolphin (Cephalorhynchus eutropia) is a species in the genus Cephalorhynchus. It is currently classified as Near Threatened on the IUCN Red List. Typically found in diverse terrestrial and aquatic ecosystems.

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.
