  2. Plains spadefoot toad - Wikipedia

    en.wikipedia.org/wiki/Plains_Spadefoot_Toad

    The tadpoles exhibit phenotypic plasticity, with some changing from an omnivorous morphology into a cannibalistic carnivorous morph with oversized jaw muscles and pronged beaks. In some cases, female spadefoot toads will choose to mate with Spea multiplicata rather than with males of their own species, if the resulting hybrid tadpole would have ...

  3. American spadefoot toad - Wikipedia

    en.wikipedia.org/wiki/American_spadefoot_toad

    American spadefoot toads have a unique diet. The adults' and tadpoles' diets vary. The adults' diet consists of invertebrates. [9] They eat flies, crickets, caterpillars, moths, spiders, centipedes, millipedes, earthworms, and snails. [10] The tadpoles' diet is related to its surroundings and food supply.

  4. Tadpole - Wikipedia

    en.wikipedia.org/wiki/Tadpole

    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.

  5. Boreal toad - Wikipedia

    en.wikipedia.org/wiki/Boreal_Toad

    Survival of tadpoles to metamorphosis is higher in aquatic environments with high trout presence, low chytrid fungus presence, and in non-permanent spawning pools. [7] Trout presence decreases predation by aquatic insects, lower chytrid fungus concentrations help tadpoles through their most vulnerable life-stage, and ephemeral spawning pools ...

  6. Great Basin spadefoot - Wikipedia

    en.wikipedia.org/wiki/Great_Basin_spadefoot

    It is usually gray, olive or brown colored. Gray streaks outline an hourglass-shaped marking on the back. The skin is smooth compared with the bumpy skin of the true toads in the genus Bufo. There is a spade present on the inside of each hind foot; it has sharp edges and is wedge-shaped. A glandular boss is present between the eyes.

  7. Western chorus frog - Wikipedia

    en.wikipedia.org/wiki/Western_chorus_frog

    Western chorus frogs live in a variety of different habitats, but areas of more permanent water increase the risk of predation on eggs and/or tadpoles. To compensate for this, chorus frogs stick to mostly ephemeral freshwater areas, such as marshes, river swamps, meadows, grassy pools, and other open areas found in mountains and prairies.

  8. Common toad - Wikipedia

    en.wikipedia.org/wiki/Common_toad

    The tadpoles also exude noxious substances which deter fish from eating them but not the great crested newt. Aquatic invertebrates that feed on toad tadpoles include dragonfly larvae, diving beetles and water boatmen. These usually avoid the noxious secretion by puncturing the tadpole's skin and sucking out its juices. [22]

  9. Strawberry poison-dart frog - Wikipedia

    en.wikipedia.org/wiki/Strawberry_poison-dart_frog

    In captivity, tadpoles have been raised on a variety of diets, ranging from algae to the eggs of other dart frogs, but with minimal success. O. pumilio tadpoles are considered obligate egg feeders, as they are unable to accept any other form of nutrition. After about a month, the tadpole will metamorphose into a small froglet.
