A) Mengapa sebagian besar kerang Hidup di pasir?
Ada kerang yang bentuknya seperti pisau dan hati. Oleh karena itu disebut “kerang pisau” dan kerang hati”. Kerang itu tinggal di pasir pantai. Jika air laut menyusut pada saat pasang surut, kerang itu mencari perlindungan agar tidak terbakar oleh matahari. Mereka mengubur diri dalam pasir. Jika air kembali kerang itu muncul sedikit di permukaan. Kulitnya tetap berada dalam air. Dengan demikian, mereka tidak tenggelam dan bisa menghisap udara. Kerang mempunyai “belalai” kecil yang dikeluarkan untuk bernapas. Makanan kerang adalah makhluk kecil yang tersaring ke luar dari laut.
B) Bagaimana Kerang Hidup?
Kerang yang baru menetas merupakan larva kecil yang terbawa arus laut. Lambat laun pada tubunya tumbuh kulit keras. Pada dasarnya, kulit itu akan menjadi sangat keras sehingga kerang itu tidak dapat berenang lagi. Mereka pun melekatkan diri pada karang atau menguur diri dalam pasir. Di sanalah mereka menghabiskan sisa hidupnya. Hanya sedikit kerang yang berenang bebas ke sana kemari. Untuk menjadi gemuk, kerang juga membutuhkan makanan. Akan tetapi, mereka bukan jenis binatang pemburu. Kerang hanya makan apa yang tersaring ke luar dari laut. Kalian harus berhati-hati terhadap kerang yang melekat di atas batu. Kulitnya yang tajam dapat melukai kaki kalian.
