Ceara White-lipped Frog

The adult Leptodactylus pustulatus is about 5 cm (2 in) long. It can easily be distinguished from other members of its genus by its distinctive ventral colouration which consists of large, red to yellow spots on a dark-coloured background. Its calls, which are heard at night, are also distinctive; the male's advertisement call consists of two notes, repeated at a rate of about twenty-six calls per minute and other males respond to these in a similarly characteristic fashion.

It is found in the Amazonia, Caatinga, and Cerrado biomes, in ponds, rivers, and gallery forest. It has also been found in pastureland, rural gardens, urban areas, and ponds in the states of Goiás, Mato Grosso, Tocantins, Ceará and Maranhão. It has been observed between 400 and 1,000 m (1,310 and 3,280 ft) above sea level. It has shown some tolerance to habitat disturbance. Much of its habitat consists of seasonally flooded areas in the Araguaia, Tocantins, Xingu and Parnaíba river systems. Scientists have reported the frog in many protected places: APA da Serra de Baturite, APA de Upaon-Acu/Miritiba/Alto Preguicas, APA Lago de Palmas, APA Lago de Santa Isabel, APA Serra da Ibiapaba, and RESEX Lago do Cedro.

The female frog seems to provide some level of parental care for the tadpoles by carrying them to water.
