Implicating tadpole → amphibian
Link to implication

Reason:

Is a term used to the aquatic juvenile form of batrachians/anurans (frogs and toads) and, more rarely, caldates/urodeles (salamanders); which are amphibians.

Related implications:

• tadpole → marine.¹

¹ tadpoles are aquatic.

Note: I believe that ought be more interesting to keep the 'larva' tag restrict to insect larvae; however it technically also would encompass tadpoles, planulas, fish larvae, echinoderm larvae, cysticercus etc.
