Tadpoles. R. draytonii is a moderate to large (4.4–14 cm or 1.7–5.5 in) frog. It is the biggest native frog species in the western United States. [10] The back is a brown, grey, olive, or reddish color, with black flecks and dark, irregular, light-centered blotches, and is coarsely granular.
Lepidurus packardi is about 5 centimeters (2.0 in) long. It has a shield-like carapace up to 3.5 cm (1.4 in) long. It has compound eyes, up to 48 pairs of phyllopods (swimming appendages), and two cercopods, pincer-like appendages at the end of its telson, or tail segment.
A tadpole or polliwog (also spelled pollywog) is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians, such as a lateral line, gills and swimming tails.
Tadpoles are green with a yellow or white stripe extending from each nostril to the eye and may have mottled tail fins. [20] American green tree frogs show only the parental investment of mating and egg-laying. [4] Breeding is known to be strongly influenced by day length, temperature, and precipitation.
As tadpoles, the squirrel tree frog is preyed upon by dragonfly nymphs, giant water bugs, predatory fish and newts. [2] [3] Once the tadpoles metamorphose, the predators of the frogs change to small mammals, other frogs, snakes, birds. [2] To reduce the danger of being eaten as tadpoles, they use dense vegetation as cover. [4]
Fortunately, a conservation team has been deployed in order to manage the recovery of the Mississippi gopher frog by managing the habitat, supplementing habitat with sufficient water, raising tadpoles for release, constructing or restoring new breeding sites, and managing ecological requirements and diseases.
The yellow-spotted tree frog is pale green with bronze patches that highlight dark spots. It has entirely webbed toes and is set apart from other frogs by the cream markings on its thighs.
Ambystoma talpoideum, the mole salamander, is a species of salamander found in much of the eastern and central United States, from Florida to Texas, north to Illinois, east to Kentucky, with isolated populations in Virginia and Indiana. Older sources often refer to this species as the tadpole salamander because some individuals remain in a ...
