（单词翻译）

 The seal is now what the killer¹ wanted, but the hunt is far from over. They need to wrap their prey² by the tail while avoiding its snapping jaws³. Only them will they be able to pull it down and drown it. Side swipes create farther underwater turbulence⁴,  a new tactic⁵. Growing bubbles gives cover for others to lunge at the seal's tail. Somehow the seal manages to reach a tiny ice floe⁶. The killers⁷ could easily grab it, but now this seems to become again. The seal's life hangs on a roll of the ice. Yet again, the pod joins forces to dislodge the seal. The seal seizes a chance to escape.
