Big Finner

Big Finner (Balaenoptera physalus) is classified as Endangered (EN) on the IUCN Red List. At high risk of extinction in the wild, with significant population decline and ongoing threats to survival.

Common Spindle

<em>Euonymus europaeus</em>, commonly known as the common spindle, is a deciduous shrub or small tree in the family Celastraceae, native to Europe and western Asia. This species typically inhabits woodland edges, hedgerows, scrubland, calcareous grassland margins, and riverbanks, preferring well-drained soils on chalk and limestone but tolerating a variety of substrates. Its geographic range extends across most of Europe from the British Isles and Scandinavia south to the Mediterranean, and eastward through the Caucasus into western Asia. Classified as Least Concern on the IUCN Red List, <em>Euonymus europaeus</em> maintains stable populations throughout its native range. The species is particularly notable for its striking autumn display of bright pink to crimson four-lobed capsular fruits that split to reveal orange-coated seeds, providing an important food source for robins, blackcaps, and other birds. The seeds are toxic to humans and many mammals. The plant typically grows to 2–6 metres in height and produces small inconspicuous greenish-white flowers in spring. Biological traits such as average individual lifespan, precise body dimensions, and specific weight measurements remain poorly documented at the population level for this shrub. The hard, fine-grained wood has historically been used for making spindles and skewers, giving rise to the common name.
