Christmas candlestick

The Christmas candlestick (Cassia alata), more commonly known as candle bush or ringworm bush, is a shrub or small tree in the family Fabaceae, native to the New World tropics, primarily Central America, Mexico, and northern South America. The species is widely naturalized throughout the tropics and subtropics globally, having spread through cultivation and accidental introduction. It produces distinctive upright, spike-like racemes of bright yellow flowers that resemble a lit candelabrum, giving rise to its common names. These inflorescences are borne at the tips of branches and can reach up to thirty centimeters in length. The large pinnate leaves are characteristic of the genus Cassia. Cassia alata has been used extensively in traditional medicine across its native and introduced range, particularly for treating fungal skin conditions such as ringworm, a use supported by documented antifungal activity of compounds in the leaves. The species grows rapidly in disturbed habitats, roadsides, and forest margins, and is considered weedy in many regions. It is a host plant for the larvae of several sulfur butterfly species. While not a significant conservation concern, its invasive tendencies in non-native regions warrant management attention.

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.
