Lumba-lumba adalah binatang yang sangat lincah dan cerdas. Selain kera, lumba-lumba juga merupakan binatang yang berintelegensia tinggi. Meskipun berjauhan, mereka saling memberitahu yang lain melalui bunyi-bunyian, seperti bersiul, mencicit, berdengung, atau mengeluarkan bunyi gemertak. Jika ada bahaya, mereka saling memberitahukan dan memanggil teman mereka untuk meminta pertolongan. Jika menemukan ikan, lumba-lumba akan segera memberitahukan temannya. Mereka juga saling memanggil untuk mencari teman bermain. Lumba-lumba merasa nyaman berada dalam kelompoknya. Mereka juga saling bercakap-cakap.

Sebenarnya, paus bukan ikan, melainkan binatang menyusui. Dari posisi ekornya yang menghadap ke atas dan bergaris tengah, kita bisa melihat perbedaan dengan ikan. Paus menghabiskan waktunya di perairan dingin di daerah kutub. Setiap dua tahun sekali, jika bayinya lahir, paus akan berenang ke perairan yang lebih hangat. Bayi paus yang baru lahir beratnya sudah mencapai 200 kg, dengna panjang 6-7 meter. Induk paus segera membawa bayinya ke permukaan air. Seperti manusia juga, paus mempunyai paru-paru dan membutuhkan zat asam di udara untuk bernapas. Induk paus juga menyusui bayinya. Bayi paus minum susu banyak sekali sehingga berat badannya setiap hari bertambah 100 kg.
