A) Bisakah binatang laut bernapas di bawah air?
Manusia dan binatang membutuhkan zat asam untuk hidup, kita menghisap zat asam tersebut pada saat bernafas. Menyelam dalam air hanya bisak ita lakukan sebentar saja karena paruh-paru kita tidak dapat menyaring zat asam dari air. Keadaan binatang laut kebanyakan berbeda. Semua ikan dan kepiting mempunyai insang. Dengan insang itu, mereka bisa mengambil zat asam dari air. Akan tetapi, jika binatang itu di bawa ke darat, mereka tidak dapat bernapas dengan insang. Di laut juga hidup binatang yang bernapas dengan paru-paru. Misalnya: paus, anjing laut dan kura-kura laut. Mereka harus sering muncul di permukaan air untuk menghirup udara.
B) Apa yang dimakan oleh binatang laut?
Makanan yang dimakan oleh binatang laut bermacam karena jenisnya tidak terhitung. Beberapa binatang laut adalah pemakan tumbuhan, sama halnya dengan binatang darat. Binatang laut itu memakan tumbuhan laut, ganggang besar, dan ganggang kecil. Sebagian lainnya pemakan ikan, mereka juga memangsa binatang yang lebih kecil dan binatang pemakan tumbuhan seperti seekor singa memangsa zebra pemakan tumbuhan. Binatang terbesar di dunia yang hidup di laut adalah paus. Panjang paus bisa mencapai 33 meter dan beratnya lebih dari 100 ton. Binatang seperti itu malah memangsa makhluk terkecil di air yaitu plankton. Plankton adalah binatang dan tumbuhan kecil yang mengambang di air.
