マメボヤ

Perophora japonica 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 Perophora, 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. Perophora japonica 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.

イルカ科で最大の種であるシャチ（Orcinus orca）は体長最大9メートル、体重6トンに達し、北極から南極まですべての海洋に生息しています。独特の方言、狩猟戦略、集団間で異なる文化的伝統を持つ母系ポッドで生活する頂点捕食者です。一部の集団は魚類を、他の集団は海洋哺乳類を専門に捕食します。天敵はなく、シャチは生息するすべての海洋食物連鎖の頂点に位置します。
