Ribeiroia ondatrae, or the frog-mutating flatworm is a parasite in the genus Ribeiroia which is believed to be responsible for many of the recent increases in amphibian limb malformations, particularly missing, malformed, and additional hind legs. It was first reported from livers of Ondatra, hence its specific name. [1]
Gastrulation in frogs commences in the marginal zone— the region encircling the blastula's equator where the animal and vegetal hemispheres meet—differing from sea urchins where it begins in the most vegetal part. In contrast to the vegetal blastomeres, the endodermal cells in the marginal zone of frogs are smaller and contain less yolk. [2]
This makes the species even more unique, as PLOS One said, because other frogs that skip the egg step typically give birth to froglets, or baby frogs, but these frogs still give birth to tadpoles.

Cruziohyla craspedopus is a high-canopy frog of primary tropical lowland rainforest at elevations of 50–600 m (160–1,970 ft) above sea level.
