典型的な魚類は[[ectothermic/ja|変温動物]]であり、速く泳ぐための[[:en:Streamlines, streaklines and pathlines|流線形]]の体を持ち、鰓で水から酸素を取り込み、2対の対鰭、1つまたは2つの背鰭、臀鰭と尾鰭、顎、[[scale (zoology)/ja|]]に覆われた皮膚を持ち、卵を産む。これらの基準にはそれぞれ例外があり、体形や生活様式に大きな多様性を生み出している。例えば、速く泳ぐ魚の中には恒温性を示すものがあり、遅く泳ぐ魚の中には流線形を捨てて別の体形を持つものもいる。
A typical fish is [[ectothermic|cold-blooded]], has a [[Streamlines, streaklines and pathlines|streamlined]] body for rapid swimming, extracts oxygen from water using gills, has two sets of paired fins, one or two dorsal fins, an anal fin and a tail fin, jaws, skin covered with [[scale (zoology)|scales]], and lays eggs. Each criterion has exceptions, creating a wide diversity in body shape and way of life. For example, some fast-swimming fish are warm-blooded, while some slow-swimming fish have abandoned streamlining in favour of other body shapes.
