My dear Watson,--I have no doubt that you can remember Tadpole Phelps, who was in the fifth form when you were in the third. 阿瑟·柯南·道尔.福尔摩斯回忆录.
The Ebers papyr us shows that the Egyptians knew of the development of the beetle from the egg, of the blow-fly from the larva, and of the frog from the tadpole. 李贝.西洋科学史.
A tadpole is for a time a fish; it becomes a land creature as it develops. 赫伯特·乔治·威尔斯.世界史纲.
The young tadpole has branching external gills that wave in the water; then a gill cover grows back over them and forms a gill chamber. 赫伯特·乔治·威尔斯.世界史纲.
From the beginning it must breathe in air; it can never breathe under water as a tadpole can do. 赫伯特·乔治·威尔斯.世界史纲.
