About this species
The rough-toothed dolphin (Steno bredanensis) is a species of dolphin that lives in deep warm and tropical waters around the world. It was first described by Georges Cuvier in 1823. The genus name Steno, of which it is the only member, comes from the Greek for 'narrow', referring to the animal's beak, which is a diagnostic characteristic of this dolphin. Its specific name honours van Breda, who studied Cuvier's writings. There are no recognised subspecies.

糙齿海豚（学名：Steno bredanensis）为海豚科糙齿海豚属的动物。分布于全球的温暖或热带的深水水域，例如南海、东海、台湾海域等海域。乔治·居维叶在1823年时首次描述此物种。它们的属名「Steno」，是来自于希腊文的「窄」，可呼应此种海豚的狭窄嘴喙，其形状为糙齿海豚的辨识特征之一，此属无其他的种类。该物种的模式产地在法国附近。 糙齿海豚有时也称为皱齿海豚，主要因为牙齿上有纵脊的粗糙表面。
