Discussion
- Tadpoles are growing faster than toads
- Males are assumed to differ from females by {p_Am} and E_Hp only
- amphibiaweb states that tadpoles grow from 1.8 to 7.6 cm in a few weeks, but most tadpoles do overwinter (pers. com. Samuel Pinya Fernandez)
Facts
- These are the only North American frog species that reproduce by internal fertilization; tail of male is part of cloaca (Ref: Wiki)
- Lacking the ability to vocalise, and in possessing free rib (Ref: Wiki)
