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。

マメボヤ

<em>Perophora japonica</em> is a colonial tunicate in the family Perophoridae with records in Europe and North America, including the United States. This species has not been evaluated by the IUCN. Like other members of the genus <em>Perophora</em>, it forms stolonate colonies in which individual zooids are connected by thin, creeping stolons rather than embedded within a shared tunic matrix, giving colonies a distinctive chain-like or branching appearance on the substrate surface. Tunicates of this type are filter feeders, drawing water through an oral siphon to extract suspended particulate organic matter, phytoplankton, and bacteria. <em>Perophora japonica</em> is associated with hard substrates in shallow coastal and estuarine environments, where it competes with other sessile invertebrates for space and resources. The species is presumed to have been introduced to European and North American waters through shipping, aquaculture, and hull fouling. Its ecology in introduced ranges is incompletely understood, and the extent of any ecological impact on native invertebrate communities has not been thoroughly assessed. Biological traits of this species remain poorly documented in the scientific literature.
