Tomato frogs are any of the three species of genus Dyscophus (family Microhylidae): D. antongilii, D. insularis, or D. guineti. [1] Dyscophus is the only genus in subfamily Dyscophinae. They are endemic to Madagascar. [2]

Contents

The common name comes from D. antongilii's bright red color. When threatened, a tomato frog puffs up its body. 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.

The lifespan of the tomato frog can be from 6 to 8 years. When adult, the colors may vary from yellowish orange to deep red. Tomato frogs will reach sexual maturity in 9–14 months. Females are larger than males and can reach 4 inches in length. Males can reach 2 to 3 inches in length. Most females range from reddish-orange bright dark red. The 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. They are also on the endangered species list. They breed in the rainy season and are nocturnal. They tend to eat small insects and invertebrates.

Reproductive activity

Tomato frogs lay fresh eggs during every month of the year except for November. Their reproductive activity is high during the months January–May and low between the months June–December. [3]

The genus Taricha consists of four species of highly poisonous newts in the family Salamandridae. Their common name is Pacific newts, sometimes also western newts or roughskin newts. The four species within this genus are the California newt, the rough-skinned newt, the red-bellied newt, and the sierra newt, all of which are found on the Pacific coastal region from southern Alaska to southern California, with one species possibly ranging into northern Baja California, Mexico.

Cophylinae Subfamily of amphibians

Cophylinae is a subfamily of microhylid frogs endemic to Madagascar. It has over 100 species in eight genera. Members of this subfamily range from minute to fairly large, and they are highly ecologically diverse. DNA barcode research has revealed a significant taxonomic gap in this subfamily, and an estimated 70+ candidate species were identified. Many of these have subsequently been described, as well as numerous new discoveries.

<i>Pyxicephalus</i> Genus of amphibians

Pyxicephalus is a genus of true frogs from Sub-Saharan Africa, commonly referred to as African bull frogs or bull frogs. They are very large to large frogs, with females significantly smaller than males. They may take decades to reach their full size potential and they are some of the longest-living frogs, possibly able to reach ages as high as 45 years.

<i>Gastrophryne carolinensis</i> Species of amphibian

Gastrophryne carolinensis, the eastern narrow-mouthed toad, is a species of microhylid frog. It is a relatively small, toad-like amphibian found in damp, shady habitats. The species is highly fossorial, and feeds primarily on ants. These North American microhylids are distinguished from true toads, and other anurans by their moist, smooth skin, their lack of eardrums or tympana, their distinguishable squat body shape, and the unique fold of skin superior to their eyes. It is found in the United States, from southern Maryland to the Florida Keys, west to Missouri and Texas. While not a true toad, it is so called because it is terrestrial.

<i>Microhyla ornata</i> Species of amphibian

Microhyla ornata. commonly known as the ornate narrow-mouthed frog, ornate narrow-mouthed toad, or ornamented pygmy frog, is a species of microhylid frog found in South Asia. This amphibian is distributed in Kashmir, Nepal, peninsular India and the Andaman and Nicobar Islands, Sri Lanka, and Bangladesh. It was previously considered to be the same species as Microhyla fissipes; therefore, the aforementioned common names can refer to either species.
