Lepidobatrachus laevis, widely known as Budgett's frog, is a species of frog in the family Ceratophryidae, discovered by John Samuel Budgett.[2] It is often kept as a pet. It has acquired a number of popular nicknames, including hippo frog,[3] Freddy Krueger frog,[3] and escuerzo de agua.[4]

Description

teeth and two "fangs" on the lower jaw. They have extremely short and stubby limbs and the forelimbs are unwebbed. L. laevis is dark olive green with darker blotches outlined in orange. The males have a dark blue throat.[4]

Diet and behavior

The wide-mouth frog is well adapted to its environment, notably the harsh

nocturnal and hunt at night, submerged up to their nostrils waiting for prey to pass by. They then lunge and swallow the prey whole.[8] They feed on other frogs, insects, and snails.[9] Both adults and tadpoles of the species are known to be occasional cannibals.[8][10][11] The tadpoles of this species are obligate carnivores that swallow their prey whole.[10] The diet of L. laevis tadpoles is similar to that of adults and includes snails, insects, other tadpoles, and crustaceans.[9] They have a different gut morphology than non-carnivorous tadpoles.[11]

Reproduction

L. laevis can produce up to 1400 eggs in a single mating. A pair will reproduce and deposit a mass of fertilized eggs in temporary pools of water. The

cannibalistic at the time of hatching and have nearly adult jaws. They sexually mature in about a year.[12]

Distribution and conservation

It is commonly observed in

habitat loss but there is a large total population size. The species is listed as Least Concern in view of its relatively wide distribution, presumed large population, and because it is unlikely to be declining rapidly enough to qualify for listing in a more threatened category.[1]

Captivity

These frogs are often kept by keepers with mild experience with frogs or advanced owners. A ten to twenty gallon tank is generally recommended, without aquarium gravel because it causes digestive issues. River stones are a better alternative. Rocks should be sloped to allow the frog to exit the water. They do not require special heating in houses with a comfortable temperature of about 72 °F (22 °C). This species of frog needs to be kept alone or with members of the same species and of equal size, as they will consume anything smaller than themselves.[3]
