Translation of "Shark's" in Japanese

The whale shark's life is mainly a solitary one.

‎ジンベエザメは ‎通常 単独で生きる

All the smell's on the kelp, so the shark's now biting and snapping at the kelp.

‎サメはにおいを嗅ぎつけ ‎ケルプを食いちぎる

Somehow she's managed to maneuver herself into the least dangerous place, and that's on the shark's back.

‎どういうわけか彼女は ‎一番 安全な場所にいた ‎サメの背中だ
