Common Seal

最も広く分布する鰭脚類であるゴマフアザラシの近縁種・ゼニガタアザラシ（Phoca vitulina）は、北大西洋と北太平洋の温帯・亜北極沿岸に生息する。成体は最大130kgに達し、海での魚・イカ・甲殻類の捕食と海岸や岩場での休息にほぼ同じ時間を費やす。大きく表情豊かな目は低照度での水中視覚に適応している。シャチ・サメ・ホッキョクグマにとって重要な食料源である。

Common thrip

<em>Thrips pini</em> is a small insect in the order Thysanoptera, family Thripidae, recorded from Denmark, Norway, Sweden, and the United States. It is Not Evaluated on the IUCN Red List. As its name suggests, this species is principally associated with pine trees, feeding on the young shoots, buds, and needle bases of <em>Pinus</em> species, where feeding damage can cause discoloration and distortion of foliage. It inhabits coniferous forests and plantations, particularly in northern and temperate regions. Like other thrips species, it is a minute insect, typically 1–2 millimeters in length, with fringed wings. Populations are typically univoltine or bivoltine in northern climates, and overwintering occurs in litter or bark crevices. Diet consists of plant tissue, primarily from pine hosts. The species has limited direct economic significance compared to some other thrips pests, but can contribute to forest health concerns when populations reach high densities. Biological traits such as precise adult body weight, lifespan, and egg output remain poorly documented in standardized scientific assessments.
