大型クジラの中で最も曲芸的なクジラのひとつであるザトウクジラは、繁殖期にオスが歌う複雑で神秘的な歌で知られており、数時間にわたって続き時間をかけて変化していきます。体長16m、体重30トンに達し、哺乳類の中で最長の回遊を行います。全海洋に分布し、協調的なバブルネット採餌でオキアミや小魚を捕食します。歴史的な捕鯨後の個体数はおおむね回復しています。

Common Motherwort

Common Motherwort (<em>Leonurus cardiaca</em>) is a perennial herbaceous plant in the genus <em>Leonurus</em>, family Lamiaceae. It is widely distributed across Asia, Europe, North America, and Oceania, with confirmed presence in countries including Australia, Belarus, Belgium, Bulgaria, and Canada, as well as Japan and 19 European nations. The species is typically found in diverse terrestrial habitats from tropical forests to temperate regions, commonly occurring in hedgerows, roadsides, disturbed ground, and open woodland edges. Currently listed as Near Threatened on the IUCN Red List, Common Motherwort requires ongoing monitoring to prevent further population decline. As a member of the mint family, it produces whorls of small pink or white flowers along an upright stem, and bears distinctively lobed leaves. It has a long history of use in traditional medicine, particularly in European and Chinese herbal traditions, where it has been employed for cardiovascular and women's health applications. The species name <em>cardiaca</em> reflects this cardiac association. Specific biological measurements such as lifespan and dimensions are not documented in available records.
