The wood frog has a complex lifecycle that depends on multiple habitats, damp lowlands, and adjacent woodlands. Their habitat conservation is, therefore, complex, requiring integrated, landscape-scale preservation. [1] Wood frog development in the tadpole stage is known to be negatively affected by road salt contaminating freshwater ecosystems ...
Pinewoods tree frog tadpole with red tail induced by the presence of predators (dragonfly larvae). Pine woods tree frogs lay eggs in ephemeral water bodies. Eggs generally hatch within 24 hours, and tadpoles metamorphose into baby froglets after 50–75 days at 11–15 mm in length. [ 3 ]
Anatomy of a wood frog tadpole (Lithobates sylvaticus) As a frog tadpole matures it gradually develops its limbs, with the back legs growing first and the front legs second. The tail is absorbed into the body using apoptosis. Lungs develop around the time as the legs start growing, and tadpoles at this stage will often swim to the surface and ...
But, for as intriguing as frogs giving birth to live tadpoles may be, PLOS One says since researchers haven't witnessed their birth in the frog's natural environment, there's still the possibility ...

Image credits: yaboi_toby_toad The wood frog can even live north of the Arctic Circle, surviving for weeks with 65 percent of its body frozen. This fella uses glucose in its blood as a kind of ...
Frog appears to have been adapted from frosc as part of this trend. [11] Meanwhile, the word toad, first attested as Old English tādige, is unique to English and is likewise of uncertain etymology. [14] It is the basis for the word tadpole, first attested as Middle English taddepol, apparently meaning 'toad-head'. [15]
Scientists in Argentina have discovered excellently preserved fossil remains of the oldest-known tadpole, the larval stage of a large frog species that lived alongside dinosaurs about 161 million ...
