A
starts withFemale tomato frogs are larger than males. Most females range from reddish-orange to bright dark red. Their bellies are usually more yellowish, and sometimes there are black spots on the throat. But males are not as brightly colored but more of a duller orange or brownish-orange. Juveniles are also dull in color and develop brighter coloration as they mature.
The Antsouhy tomato frog occurs in western Madagascar. It inhabits subtropical or tropical dry forests, subtropical or tropical moist lowland forests, dry savanna, moist savanna, intermittent rivers, and intermittent freshwater marshes.
Little information is known about the behavior of this species. In general tomato frogs are solitary and spend the majority of their time on the ground. They are active at night moving around, calling loudly, or hunting. They are ambush predators and wait patiently for potential prey; when an insect passes they will stick out their tongue to catch it. During the day they usually hide in mud or under leaf litter. When threatened, tomato frogs puff up their bodies. When a predator grabs a tomato frog in its mouth, the frog's skin secretes a thick substance that numbs up the predator's eyes and mouth, causing the predator to release the frog to free up its eyes. The gummy substance contains a toxin that occasionally causes allergic reactions in humans. The allergic reaction will not kill a human and the frog secretes it only when frightened.
Tomato frogs are carnivores (insectivores) and feed mainly on a wide variety of small invertebrates and arthropods.
Tomato frogs are polygynandrous (promiscuous) which means that both the males and the females of this species have multiple partners. Females lay small eggs on the surface of the water. These eggs will hatch about 36 hours later. Tadpoles undergo metamorphosis into juveniles and will become reproductively mature between 2 and 4 years of age.
Antsouhy tomato frogs are not considered threatened at present but they suffer from the loss of their native habitat and sometimes are captured for the pet trade.
According to IUCN Red List, the Antsouhy tomato frog is common throughout its range but no overall population estimate is available. Currently, this species is classified as Least Concern (LC) on the IUCN Red List but its numbers today are decreasing.
