Common Eyelash

The Common Eyelash (<em>Scutellinia scutellata</em>) is a small cup fungus belonging to the genus Scutellinia within the family Pyronemataceae. It is recognised by its distinctive scarlet to bright red disc-shaped fruiting body, typically measuring just a few millimetres across, and fringed with dark brown hair-like structures resembling eyelashes, from which its common name derives. This species is native to Asia and Europe and North America, and typically inhabits decomposing wood, moist soil, and other organic substrates in humid environments. Its geographic range is wide, with confirmed records across Asia including Taiwan, Europe including Belgium, Denmark, Norway, and Portugal, North America including the United States, and South America including Brazil. <em>Scutellinia scutellata</em> is assessed as Least Concern on the IUCN Red List, reflecting its broad distribution and apparent abundance. Biological traits such as lifespan, size, and specific dietary habits remain poorly documented in the scientific literature, though as a saprotrophic fungus it typically obtains nutrients by decomposing dead organic matter.

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.
