They are often mistaken for the closely related leopard frog. Larger tadpoles complete metamorphosis more efficiently because they used less energy total for the process than smaller tadpoles but energy costs are actually positively correlated with tadpole mass and duration of metamorphosis. [18]
The tadpoles develop into a streamlined, or elongated, shape and reach a length of 50mm (2 inches) preceding their complete metamorphosis, which occurs over an average period of 75 days in the summer. Similar to the metamorphised adults they have a rounded head with golden eyes, although the sides of the iris are more shaded.
A dragonfly in its final moult, undergoing metamorphosis, it begins transforming from its nymph form to an adult. Metamorphosis is a biological process by which an animal physically develops including birth transformation or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation.

Young frog with a stumpy tail, metamorphosis nearly complete. Adults. A Xenopus laevis froglet after metamorphosis. Adult frogs may live in or near water, ...
Holometabolism, also called complete metamorphosis, is a form of insect development which includes four life stages: egg, larva, pupa, and imago (or adult). Holometabolism is a synapomorphic trait of all insects in the superorder Holometabola. Immature stages of holometabolous insects are very different from the mature stage.
The presence of fish in breeding ponds shortens mating periods, whereas many other frog species avoid breeding in such conditions. All tested frog species, K. senegalensis included, immediately stopped breeding activity when the catfish species Clarias gariepinus is introduced. [12] They take 50–60 days to complete metamorphosis. [11]
Tadpoles average slightly over 1 in (3 cm) long and require 80 to 180 days to complete metamorphosis in the field. [6] The Mississippi gopher frog possesses several defense mechanisms in its immune system that are unique to Rana sevosa. The frog's innate immune system is adept at recognizing outside prokaryotic pathogens.
At the start of the rainy season, the tadpoles move to lentic water, where they will complete their metamorphosis, feeding on anuran eggs, other tadpoles, and carrion. [ 1 ] [ 4 ] Other frog species do not lay their eggs until the first heavy rains; the head-start of the L. labyrinthicus tadpoles allows them to take advantage of the eggs and ...
