Colonial bentgrass

<em>Agrostis capillaris</em>, colonial bentgrass, is a perennial grass in the family Poaceae with an extensive native range across Europe and naturalised populations in North America, South America, and Oceania, including Australia and New Zealand. This species is highly adaptable, colonising tropical and subtropical moist broadleaf forests, temperate grasslands, disturbed soils, roadsides, and cultivated landscapes within the Neotropical realm. It is assessed as Least Concern by the IUCN. Colonial bentgrass is a fine-leaved, low-growing species often used in lawn and sports turf applications due to its tolerance for close mowing and its capacity to form dense, even swards. Its panicle inflorescences bear numerous small spikelets on delicate, hair-like branches, giving the species a feathery appearance when in flower. In its naturalised range, <em>Agrostis capillaris</em> can become invasive, competing with native grass species in acid grasslands and open heathlands. The species tolerates acidic and nutrient-poor soils, attributes that contribute to its widespread persistence in degraded landscapes. Biological traits of this species remain poorly documented in the scientific literature.

Common Seal

가장 널리 분포하는 기각류인 항구물범(Phoca vitulina)은 북대서양과 북태평양 양쪽의 온대 및 아북극 연안에 서식한다. 성체는 최대 130kg에 달하며 바다에서 어류·오징어·갑각류를 사냥하고 해변이나 바위 위에서 쉬며 비슷한 시간을 보낸다. 크고 표정 풍부한 눈은 저조도 수중 시야에 적응되어 있다. 범고래·상어·북극곰의 중요한 먹이원이다.
