The transition itself can only be illustrated and corroborated by transitional fossils, which never demonstrate an exact half-way point between clearly divergent forms. [ 40 ] The fossil record is very uneven and, with few exceptions, is heavily slanted toward organisms with hard parts, leaving most groups of soft-bodied organisms with little ...
The transition from a body plan for gill-based aquatic respiration and tail-propelled aquatic locomotion to one that enables the animal to survive out of water and move around on land is one of the most profound evolutionary changes known.
Squamata (/ s k w æ ˈ m eɪ t ə /, Latin squamatus, 'scaly, having scales') is the largest order of reptiles, comprising lizards and snakes.With over 12,162 species, [3] it is also the second-largest order of extant (living) vertebrates, after the perciform fish.
The intestines shorten as they transition from a herbivorous diet to the carnivorous diet of adult frogs. Tadpoles vary greatly in size, both during their development and between species. For example, in a single family, Megophryidae, length of late-stage tadpoles varies between 3.3 centimetres (1.3 in) and 10.6 centimetres (4.2 in). [6]

However, even though Frog explains the situation, the turtle, plus some lizards, a grass snake, a pair of dragonflies, and a field mouse all become curious to see Toad's bathing suit.
Possibly being the largest subspecies of gopher snake on average, mature specimens can have an average weight in the range of 1–1.5 kg (2.2–3.3 lb), though the heavier known specimens can attain 3.6–4.5 kg (7.9–9.9 lb), with larger specimens being quite bulky for a colubrid snake.
