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.

Emperor Penguin

세계에서 가장 큰 펭귄인 황제펭귄(Aptenodytes forsteri)은 키가 최대 1.2m에 몸무게가 45kg에 달하며, 지구상에서 가장 혹독한 환경인 남극 대륙에 서식합니다. 영하 60°C 이하의 한겨울 암흑 속에서 번식하며, 수컷이 암컷이 바다에 있는 동안 65일 동안 발 위에서 육아낭 아래에 알 한 개를 품습니다. 수천 마리가 모인 무리에서 개체들이 따뜻한 중심부를 순환하는 이른바 허들링 행동은 협동적 생존의 훌륭한 사례입니다.
