Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpoles have been found dating back to the Middle Jurassic. [1]
The common toad, European toad, or in Anglophone parts of Europe, simply the toad (Bufo bufo, from Latin bufo "toad"), is a toad found throughout most of Europe (with the exception of Ireland, Iceland, parts of Scandinavia, and some Mediterranean islands), in the western part of North Asia, and in a small portion of Northwest Africa.
These are frog eggs. This is how we're used to frogs having babies. They lay eggs, those eggs hatch into tadpoles ... and you learned the rest in science class. However, a newly discovered species ...
Eggs can hatch in under 30 hours and tadpoles can fully develop in one month. [13] They have wide caudal fins and two rows of labial teeth on the top of their mouths and four rows on the bottom. [14] Tadpoles survive on algae and will occasionally eat other tadpoles, [13] and on rare occasions, recently metamorphosed juveniles. [15]

The tadpoles then swim out into the open water and rapidly complete their development. [121] Madagascan burrowing frogs are less fossorial and mostly bury themselves in leaf litter. One of these, the green burrowing frog ( Scaphiophryne marmorata ), has a flattened head with a short snout and well-developed metatarsal tubercles on its hind feet ...
The African bullfrog is an exotic pet in many countries around the world. Animals sold are generally bred in captivity. Pet African bullfrogs may live for 35 years in captivity. [5] As pets, African bullfrogs are considered to be easygoing and low-maintenance in terms of their care. [21] It is considered a delicacy in Namibia. [22]
The loss of some tadpoles in the metamorphosis from tadpole to frog is a unique feature of R. darwinii. This observation is likely explained by these hypotheses: The tadpoles that did not survive were converted into nutrition for the foster male and he digested them. [13] The tadpoles died in the vocal sac of the foster male.
