| 1. | When it swims , its long flowing caudal fins make it look like a fairy dancing gracefully
游动时长鳍飘飘，宛似仙子起舞。 |
| 2. | Looked at from above , its round body and wide spreading caudal fins resemble the chinese character " ? " ( wen )
从上俯视，鱼体浑圆，尾鳍散开，极像文字，因而得名。 |
| 3. | Among the hundreds of guppy varieties , the best known feature of the male fish is its gorgeous dorsal and caudal fins
在成千上百的孔雀鱼品种中，雄鱼最著名的特色就是它们华丽的背鳍和尾鳍。 |
| 4. | The long and broad caudal fins are curved downwards slightly . it moves gracefully like a phoenix displaying its ornate plumage
尾鳍宽长，微垂向下，泳姿优雅有如凤凰展翅，故名蛋凤或丹凤。 |
| 5. | The study object in this paper is a lunate caudal fin imitating tuna - tail with the mode combined swaying and yawing in uniform flow which is incompressible and inviscid
