Choaky Berry

The Choaky Berry (Eugenia axillaris), also known as White Stopper, is a native evergreen shrub or small tree in the family Myrtaceae, occurring in coastal scrub, hammock forests, and pine rockland habitats of South Florida, the Caribbean islands, and parts of Central America. It belongs to the large genus Eugenia, which encompasses over 1,000 species of tropical and subtropical trees and shrubs — many producing edible fruits used locally as food. White Stopper typically reaches 3–10 metres in height, producing opposite, elliptic leaves with a leathery texture and small, white, four-petalled flowers with numerous stamens. The fruits are small, fleshy drupes that ripen from green through red to black-purple and are consumed by birds, which serve as the primary seed dispersers. The species is an important component of subtropical coastal and hammock ecosystems in Florida, providing food for frugivorous birds including warblers, thrushes, and vireos during migration. Its dense branching provides nesting cover for native songbirds. The IUCN classifies Eugenia axillaris as Least Concern. The name stopper traditionally refers to the genus's reported astringent properties — the juice of the fruit was used medicinally to treat diarrhoea. It is a valuable native plant for restoration and landscaping in South Florida gardens.

Common Water Rat

<em>Hydromys chrysogaster</em>, commonly known as the common water rat or rakali, is a semi-aquatic rodent in the family Muridae, native to Australia and New Guinea. It is classified as Least Concern by the IUCN, reflecting its relatively stable population across a broad range of freshwater and estuarine habitats on the Australian continent and associated islands. The species typically inhabits the banks of rivers, lakes, wetlands, and estuaries, where it constructs burrows in streambanks. It is highly adapted for an aquatic lifestyle, with partially webbed hind feet, a flattened head, and a dense waterproof coat. <em>Hydromys chrysogaster</em> is a carnivore, typically feeding on fish, crustaceans, mussels, frogs, and aquatic invertebrates, which it often carries to elevated feeding platforms to consume. The species is nocturnal and crepuscular, most active during early morning and evening hours near the water's edge. Biological traits including average lifespan, body length, and weight remain poorly documented in standardized databases, though adults are generally robust for a rodent, reportedly reaching body lengths of 20–35 cm excluding the tail. Geographic range details for this particular record remain incompletely documented in available data sources. Ecologically, the common water rat is an important apex predator in small-scale freshwater food webs and serves as an indicator species for wetland health in Australian riparian systems.
