Habitat & Geographic Range
Cliff Stiletto
Typically found in virtually all terrestrial and freshwater habitats.
Distributed across Denmark, Norway, and Sweden.
pinguim-imperador
Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.
Found in Norway. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.
Cliff Stiletto
The Cliff Stiletto is a member of the stiletto fly family Therevidae, a family of predatory flies whose larvae inhabit soil, sand, and decomposing wood. Stiletto flies are slender, pointed-bodied dipterans with a sharp-tipped abdomen, giving rise to the family name. Adults are typically found basking on sun-exposed surfaces including cliff faces, rocky ground, and sandy banks, where they hunt other small insects. The larvae of most Therevidae species are predatory soil-dwellers, feeding on other invertebrate larvae in loose, sandy, or gritty substrates. Cliff-associated species may exploit the loose, dry substrates in cliff-face crevices and the compacted soils of cliff bases as larval habitat. The family Therevidae is distributed globally, with greatest diversity in xeric and Mediterranean-climate regions where open, sandy, or gravelly habitats are prevalent. Stiletto flies as a group have received relatively little study compared to larger fly families, and the taxonomy, host associations, and conservation status of many species remain poorly documented. Adults are often short-lived and are found only during the warmer months when insect activity is highest on cliff and rocky habitat.
pinguim-imperador
O maior pinguim do mundo, os pinguins-imperadores medem até 1,2 metro de altura e pesam 45 kg, habitando o continente antártico em algumas das condições mais extremas da Terra. Reproduzem-se no meio do inverno, na escuridão, a temperaturas abaixo de -60°C, com os machos incubando ovos únicos sobre os pés sob uma bolsa de criação por 65 dias enquanto as fêmeas estão no mar. Seu comportamento de aglomeração — onde os indivíduos revezam-se pelo centro quente de grupos de milhares — é uma obra-prima de sobrevivência cooperativa.
