Anura, comprised of frogs or toads, is the most diverse of the three existing amphibian orders. There is no formal distinction between frogs and toads, just that toads are typically a more warty frog species. Frogs live in every biome except in extremely dry deserts and polar regions, however, their species diversity is most abundant in the tropics. Frogs are typically carnivores though some eat fruit, and all adult frogs, except one species, do not have tails—thus where the the name Anura, meaning “without tail,” came from. There are about 4,000 different species of frogs with the earliest known fossils dating back to the Jurassic period.

What do frogs eat?

Frogs are carnivores. A smaller frog’s diet consists of insects like flies, mosquitoes, moths, spiders, and dragonflies. Larger frogs also eat insects like grasshoppers, butterflies, and worms, and may even eat small snakes, mice, baby turtles, and other smaller frogs.

How do frogs reproduce?

Frogs reproduce by the male and female frog getting into the mating posture, amplexus, to make sure the eggs become fertilized. Egg fertilization happens outside of the female’s body when she releases her eggs and the male releases his sperm at the same time. The eggs are then placed in water and will hatch into tadpoles which later become frogs.

Why do frogs croak?

In almost all frog species it is the males that croak and they do so to attract female frogs. Males frogs tend to croak while they are in or near a water source (ponds, dams, streams, or wetlands) with the intention of mating. Each frog species has a different croak and can be identified by it.

Red-Eyed Tree Frog (Agalychnis callidryas)
Comparison illustration of the size of a Red-Eyed Tree Frog to other frogs

The red-eyed tree frog, Agalychines callidryas, is an arboreal hylid that lives in the Neotropical rainforests of Mexico to Central America and Colombia. They are named after their red eyes with vertically narrowed pupils; other physical traits include a vibrant green body with yellow and blue vertically striped sides, webbed orange or red feet, and a soft belly. They spend a majority of their lives in trees and are excellent jumpers. Their red eyes can momentarily startle predators, giving the frog a chance to escape. Red-eyed tree frogs are insectivores, as they eat crickets, moths, grasshoppers, flies, and other insects.

The Red-Eyed Tree Frog has an overall length between 2”-3” (5.1-7.6 cm), body width of .91”-1.5” (2.3-3.8 cm), sitting height of roughly 1.22”-1.77” (3.1-4.5 cm), and weight between .2-.5 oz (2.8-14 g). The typical lifespan of the Red-Eyed Tree Frog is between 4-12 years.

Pickerel Frog (Lithobates palustris)
Scale illustration of an average Pickerel Frog compared to other frog species

The pickerel frog, Lithobates palustris, is a small North American frog known for its appearance of seemingly ”hand-drawn” squares on its dorsal surface; there are seven to twenty-one of these rectangular dark brown spots in two columns down its back. They like to live near cold and clear water, and prefer rocky ravines, bogs, and meadow streams, but they can also be found in heavily wooded lakes and rivers. Their diet consists of ants, spiders, beetles, sawfly larvae, and other invertebrates, and the pickerel frog will catch its prey in grassy areas next to bodies of water.

The Pickerel Frog has an overall length between 1.75”-3.5” (4.4-8.9 cm), body width of .67”-1.34” (1.7-3.4 cm), sitting height of roughly .8”-1.57” (2-4 cm), and weight between .09-.12 oz (2.5-3.5 g). The typical lifespan of the Pickerel Frog is between 5-8 years.

African Dwarf Frog (Hymenochirus boettgeri)
Scale illustration of an average African Dwarf Frog compared to other frog species

The African dwarf frog, Hymenochirus, is an aquatic frog native to Equatorial Africa. It is often mistaken for the African clawed frog, a frog in the same family of similar appearance. The African dwarf frog is also known as the dwarf clawed frog, and its common name references their place of origin and the claws on their front legs. Physically they are small in size and vary in color- from olive green to brown with black spots. They do not have a tongue or teeth and are completely aquatic, and because of their low maintenance, they are desirable pets.

The African Dwarf Frog has an overall length between 2”-3” (5.1-7.6 cm), body width of .83”-1.34” (2.1-3.4 cm), sitting height of roughly .67”-1.02” (1.7-2.6 cm), and weight between .05-.07 oz (1.5-2 g). The typical lifespan of the African Dwarf Frog is between 8-15 years.

Golden Poison Frog (Phyllobates terribilis)
Comparison drawing of the Golden Poison Frog compared to other frogs

The golden poison frog, Phyllobates terribilis, is a poison dart frog that lives in the humid forest of the Pacific coast of Colombia in the Cauca and Valle del Cauca Departments in the Choco Rainforest. Due to destruction of the rainforests, the habitat is limited in size, and the golden poison frog is on international endangered species lists. They are small in size and bright in color, but they are lethally toxic. Their main source of food are ants, but they also eat small invertebrates and other insects. Local indigenous cultures use the frogs’ poison in darts for hunting.

The Golden Poison Frog has an overall length between 1.75”-2.2” (4.4-5.6 cm), body width of .79”-1.02” (2-2.6 cm), sitting height of roughly 1.3”-1.65” (3.3-4.2 cm), and weight between .5-1 oz (14-28 g). The typical lifespan of the Golden Poison Frog is between 10-20 years.

Mink Frog (Lithobates septentrionalis)
Comparison illustration of the size of a Mink Frog to other frogs

The mink frog, Lithobathes septentrionalis, is a small frog species that is native to the United States and Canada. Its name references their scent, which reportedly smells like a mink.  Physically they have a green dorsum with darker green and brown blotching; their belly is cream, yellow, or white. The mink frog lives in predominantly aquatic areas among vegetation in ponds, swamps, and streams in wooded areas. As tadpoles they eat mostly algae and decaying plant matter, and as they age they feed on spiders, snails, beetles, and other invertebrates.

The Mink Frog has an overall length between 1.8”-3” (4.5-7.6 cm), body width of 1.06”-1.81” (2.7-4.6 cm), sitting height of roughly .94”-1.57” (2.4-4 cm), and weight between .05-.07 oz (1.5-2 g). The typical lifespan of the Mink Frog is between 5-6 years.
