Description
provided by AmphibiaWeb articles
A large conspicuously coloured frog. M 60-65 mm, F 90-95 mm. Dorsum yellowish in males, red-orange in females, often with many small reticulations. In both sexes often with a rhomboid dark marking. Ventrally uniform whitish. Skin smooth with two dorsolateral folds. Tympanum rather indisctinct, about 1/3 of eye diameter. Tibiotarsal articulation reaches the tympanum. Fingertips not enlarged. A large inner metatarsal tubercle. No webbing on hands, weakly expressed webbing on feet (Glaw and Vences 2007). Similar species: Very similar to D. antongilii and only distinguishable by the relatively faint colour differences (Glaw and Vences 2007).Taken with permission from Glaw and Vences (2007).

Distribution and Habitat
provided by AmphibiaWeb articles
This species occurs widely along the eastern rainforest belt of Madagascar. It is a very secretive species and probably occurs at many more localities than records indicate (Nussbaum et. al 2008). Located at Ambatovaky, Andekaleka, Ankay, Antsihanaka, Fierenana, Sambava, Soavala, Vevembe (Glaw and Vences 2007) from 150 to 900 m asl (Nussbaum et. al 2008).

Life History, Abundance, Activity, and Special Behaviors
provided by AmphibiaWeb articles
Habits: Reliably only known from primary forest, usually in areas that are relatively flat and where streams are slow-moving, forming large almost stagnant parts and side-ponds. At these sites specimens can be very common and easy to find, especially at night when they move on the forest floor. Many hundreds of sticky eggs are deposited in these ponds (Glaw and Vences 2007). Calls: Similar to that of D. antongilii (Glaw and Vences 2007).

Life History, Abundance, Activity, and Special Behaviors
provided by AmphibiaWeb articles
This species is listed as least concern because of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.It is not known from any protected areas and its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, and invasive spread of eucalyptus, livestock grazing and expanding human settlements. It is exploited commercially, but probably not at a level that seriously impacts populations. This exploitation results largely from the placement of its sister species, Dyscophus antongili (the Tomato Frog), on Appendix I of CITES. The trade in this species should be regulated through a quota (Nussbaum et. al 2008).

Dyscophus guineti
provided by wikipedia EN
Dyscophus guineti, the false tomato frog or the Sambava tomato frog, is a species of frog in the family Microhylidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical swamps, swamps, freshwater marshes, intermittent freshwater marshes, and heavily degraded former forest. It is threatened by habitat loss.
Description, The Dyscophus guineti male frogs are yellowish, and in size 60-65mm. The female frogs are red- orange often with many small reticulations, in size 90-95mm. Some of these frogs have an Odontoma which are tumors from a tooth that also contain tissue. These cause bad tooth eruption and displacement of erupted teeth.[3] Another aspect which concerns these frogs is the way they capture their prey using their tongues and mouth. It is based on how close their prey is to them, the way they capture it changes. If their prey is smaller and at an azimuthal location of less than 40A degrees, they will aim their heads at the prey and not their tongues. If their prey is larger and at an azimuthal location greater than 40A then they proceed to aim both their head and tongue at their prey. The process when the prey is larger is better known as hydrostatic elongation. The dysciphus guinteti also has tongue movements sperate of the lower jaw which changes their speed, momentum, and projection of their tongue in different situations. [4]
