呢個目所有成員都食肉，以海洋海豚科嘅動物最出名。其中樽鼻海豚最聰明，佢地嘅智商可以有三歲細路咁高[未記出處或冇根據]。
解剖學特徵
齒鯨只有一個呼吸孔，喺頭部前方接近嘴唇部位置。同鬚鯨亞目相比，齒鯨體長較細，除咗抺香鯨之外，一般體長大約得10米，嘴喙明顯（除咗殺人鯨、偽虎鯨同抺香鯨）。
行為特徵
(1)鳴叫：大部分齒鯨亞目既成員可以發出鳴叫，而且叫聲有好多種。
(2)運動：齒鯨游泳動作較為迅速同靈活，細隻啲品種有騎狼行為。
(3)社會行為：齒鯨大多結群活動，種群數量較大，海豚種群有時可達成千條之多。
(4)食啲乜：所有齒鯨都係食肉既，主要都係魚，蝦等水產，要視乎係乜嘢品種。特別啲品種：殺人鯨會食海獅等大型哺乳動物，抺香鯨會捉巨型鳥賊嚟食。
