Lepidobatrachus laevis
A flattened frog whose head makes up a third of its body length. It is a fully aquatic species that waits for prey with only its eyes and nostrils above the surface, and an aggressive one: when threatened it inflates itself, shrieks and bites.
Lepidobatrachus laevis is a frog of the family Ceratophryidae from the Chaco of South America and the largest species in its genus. It measures 11 to 12 cm, with males only about half the size of females. The colour is greenish grey, sometimes with orange or green blotches. The head accounts for about a third of the body length and the mouth is strikingly wide, with a row of teeth on the upper jaw and two fang-like projections near the middle of the lower jaw. The limbs are short and the forelimbs unwebbed, and adult males have a dark blue throat. It is a fully aquatic inhabitant of swamps and lagoons, lying in water or mud with only its eyes exposed to ambush prey. In the dry season it aestivates in the mud inside a cocoon of shed skin. When threatened it inflates its body, gives a shrill shriek and bites. Breeding takes place in the rainy season, with around 2,000 eggs laid at a time; the tadpoles are carnivorous and cannibalistic from hatching and grow rapidly, reaching 4 to 5 cm within about a month. Animals reaching Japan are mostly captive-bred.

As a fully aquatic species the figure to control is water temperature, held at 25-28C with a thermostatically controlled aquarium heater. Frogs kept in cool water feed poorly and are more prone to illness. Water level and temperature are lowered in stages only when deliberately inducing aestivation, not in routine keeping.
Keep it in an aquarium or bare tank with enough depth for its nostrils to reach the surface, not in the shallow water used for horned frogs. An adult is commonly kept in a tank of about 60 x 30 x 38 cm with 15 to 23 cm of water; it swims strongly and copes with 30 cm without difficulty. Good filtration greatly reduces the need for water changes.
It is carnivorous and takes earthworms, crickets, roaches and waxworms. It feeds readily and is prone to obesity; a healthy adult should be longer than it is wide. Fish must be warmed to destroy thiaminase and allowed to cool before being offered. Adults on a varied diet need supplements only about once every two weeks.
It is aggressive, inflating itself, shrieking and biting when threatened, and it is cannibalistic, so keep it alone outside the breeding season. It launches itself out of the water at approaching food, so take care when offering prey with tongs.
The species is not listed in the CITES appendices, and it is neither a specified animal nor an invasive alien species under Japanese law. Commercial breeding using hormones has made it more readily available in recent years. As an amphibian its skin is sensitive, so wash and wet your hands before handling; its bite is powerful, so avoid handling it bare-handed.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The average lifespan of Budgett's Frog is 15-20 years. With proper care and nutrition, they can live a long and healthy life.
Budgett's Frog typically reaches 11-12cm; males about half the size of females as an adult. Size may vary depending on care conditions and individual genetics.
Budgett's Frog feeds on: Earthworms, crickets, roaches and waxworms, plus fish. Aim for a balanced diet with appropriate feeding frequency.
