sperm
常考释义
And this dynamism often depends on large predators. At sea the potential is even greater: by protecting large areas from commercial fishing, we could once more see what 18th-century literature describes: vast shoals of fish being chased by fin and sperm whales, within sight of the English shore.
这种生态活力活跃与否，取决于大型捕猎者。在海洋生态系统中，这一潜能更加巨大：通过禁止商业捕鱼来保护大片海洋，我们得以再次目睹18世纪文学作品中所描述的景象：在英格兰海岸上，成群的鱼群受到鲨鱼和抹香鲸的追逐。
