Wyoming Toad (Anaxyrus baxteri)


The Wyoming Toad (Anaxyrus baxteri) or Baxter’s toad is a toad native to the United States specifically Wyoming. Sadly the toad can rarely be seen in the wild anymore besides the Mortenson Lake National Wildlife Refuge in Wyoming. Its a member of the family Bufonidae, the true toad family. The Wyoming toad is the most endangered amphibian in North America.

In 1980, scientists determine that there was only 25 of these toads left in the wild. They took some of the toads for a captive breeding program and have been working on restoring the population. Problems are that Chytrid fungus as been identified in the native habitat of the toads, killing them off.

paraleastconcernParadoxical frog (Pseudis paradoxa) is a member of the genus Pseudis, the swimming frog genus in the tree frog family, Hylidae. They are found in Argentina, Bolivia, Brazil, Colombia, French Guiana, Guyana, Paraguay, Peru, Suriname, Trinidad and Tobago, and Venezuela.

The frogs reach sizes of 1.7 to 2.5 inches but they have been known to get 2.9 inches long. What makes the Paradoxical frog interesting is that the tadpoles are bigger than the adult frogs. Tadpoles reach sizes of up to 7.8 inches long, roughly 3-4 times larger.

They grow between 2.4 – 3.5 inches long. The frogs reproduce from March to late June and lay 670-4500 per clutch. After the frogs breed, the parents both go their separate way and leave the eggs by themselves.

Giant leaf frog (Phyllomedusa bicolor)


The Giant leaf frog  (Phyllomedusa bicolor) is a member of the tree frog family, Hylidae. They are found in the rain forest in South America specifically the countries of  Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela.

The females of the species grow larger than the males, reaching 4.3 – 4.7 inches long while the males only reach 4.05 inches long. The frogs spend their lives in the trees and even reproduce there. They lay their eggs on leaves of trees that over hang the water. After 8 days, the eggs drop into the water.

The Giant leaf frog contains some interesting peptides. They are  deltorphin,  deltorphin I, deltrophin II, and dermophin. They are natural opioids that are 30-40 times more potent that morphine and are theoretically be less likely to produce drug tolerance and addiction.

Colorado River toad (Incilius alvarius)


The Colorado River toad  (Incilius alvarius) is a member of the family Bufonidae, the true toad species. They can grow to lengths of 7.5 inches long and are the largest native toad in the United States. They are found in on the border on Mexico and the United States in Arizona, New Mexico, and California.

The toad is most known for producing 5-MeO-DMT, an hallucinogen. Its the only animal on earth that creates the substance. It also produces Bufotenin, which is also a hallucinogen commonly found in toads. Both drugs are illegal to posses, distribute, buy, or manufacture in the USA. If you aren’t big into the federal government telling you what to do and want to experiment, Bufatenin is toxic that has caused people to be poisoned and die.
