least concern
Common Name: Coastal Plains Toad
Scientific Name: Incilius nebulifer
Family: Bufonidae – True Toad Family
Location: Mexico and the United States
US Locations: Texas, Louisiana, and Mississippi
Size: 5 inches

The Coastal Plains Toad used to be part of the Gulf Coast Toad (Incilius valliceps) species but was split off due to genetic testing. It is still kinda confusing even though it happened over 20 years ago.

The spring and summer rains bring the males out to start calling to attract females. They will breed in a variety of still-water sources such as ponds, wetlands, and roadside ditches. Females can lay up to 20,000 eggs in a clutch and have been observed to lay two clutches in extended breeding seasons. Neither the male or female show any parental care towards the eggs. The eggs will hatch in a day or two and the tadpoles will complete metamorphosis in 20 to 30 days.

The Coastal Plains Toad has adapted alright to the urbanization of their habitat. They have been observed to hide under concrete slabs and in cracks and holes of sidewalks.

North American Green Toad (Anaxyrus debilis)

least concern
Common Name: Green Toad, North American Green Toad
Scientific Name: Anaxyrus debilis
Family: Bufonidae – True Toad family
Locations: Mexico and the United States
US Locations: Arizona, Colorado, Kansas, New Mexico, Oklahoma, and Texas
Size: 1.4 inches

The North American Green Toad is found in the south-central United States and down to Mexico. It is often called just the Green Toad but that often leads to confusion with the European Green Toad (Bufo viridis). There are two subspecies of North American Green Toad that are recognized today, the Western Green Toad (Anaxyrus debilis insidior) and the Eastern Green Toad (Anaxyrus debilis debilis). 

Breeding takes place during or after the summer rains come. When these rains arrive from Match to June, depend on location. As explosive breeders, the Green Toad generally only takes a few days to breed in temporary ponds filled by the summer rains. These ponds are free of some of the common predators of the toad’s eggs and tadpoles such as fish. They make amazing breeding sites besides the fact that they will eventually dry up.

 

 

 

Frog of the Week

least concern
Common Name: Western Toad
Scientific Name: Anaxyrus boreas
Family: Bufonidae – True Toad family
Locations: Canada, Mexico, and the United States
US Locations: Alaska, California, Colorado, Idaho, Montana, New Mexico, Nevada, Oregon, Utah, Washington, and Wyoming
Size: 5 inches

The Western Toad is found in western North America, from Alaska down to Baja California. There are two subspecies of the toad, the California Toad (A. b. halophilus) and the Boreal Toad (A. b. boreas). The California Toad is found in California (duh), northern Baja California, and western Nevada. The Boreal Toad is found in the northern parts of the range.

Some populations of the Western Toad are not doing so hot. Western Toads are listed in Colorado as an endangered species. They are listed as a protected species in Wyoming. Chytrid Fungus, a deadly pathogen, seems to be the main problem for the Western Toads. Habitat destruction is another problem for the toads.

Mexican Spadefoot Toad (Spea multiplicata)

leastconcern
Common Name: Mexican Spadefoot Toad, New Mexican Spadefoot Toad, Southern Spadefoot Toad, Desert Spadefoot Toad
Scientific Name: Spea multiplicata
Family: Scaphiopodidae – American Spadefoot Toad family
Locations: Mexico and the United States
US Locations: Arizona, Colorado, New Mexico, Oklahoma, Texas, and Utah
Size: 2.5 inches

The Mexican Spadefoot Toad is found in the southwestern United States and most of central Mexico. Like all spadefoot toads, the Mexican Spadefoot Toad does have keratinized spade-like projections on their hind legs. They use these spades to burrow into the ground. The Mexican Spadefoot Toad spends most of the day underground, coming up at night to hunt and look for mates. For mating, it usually takes place after heavy rains. Breeding periods only last one or two days in ponds and pools that form from the rains. These pools and ponds only last a few weeks. Therefore, the eggs hatch in a few days and it only takes the tadpoles a couple weeks to undergo metamorphosis.

Common Name: Fowler’s Toad
Scientific Name: Anaxyrus fowleri
Family: Bufonidae
Location: Canada and the United States
US Location: Alabama, Arkansas, Connecticut, District of Columbia, Delaware, Florida, Georgia, Iowa, Illinois, Indiana, Kentucky, Louisiana, Massachusetts, Maryland, Michigan, Missouri, Mississippi, North Carolina, New Hampshire, New Jersey, New York, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, Vermont, West Virginia

The Fowler’s Toad is named in honor after naturalist Samuel Page Fowler, who formed the Essex County Natural History Society, which became the Essex Institute and merged Peabody Museum of Salem to form the Peabody Essex Museum in Salem, Massachusetts. The Fowler’s Toad is found mostly in the eastern United States and barely in southern Canada. They breed during summer, from June to August, and the farther south they are, the later they breed. They can lay between 2000 to 10000 eggs in a clutch.

Harlequin Toads (Atelopus)

 

 

Family: Bufonidae
Number of Species: 97
Location: Central and South America

The members of the genus Atelopus are commonly referred to as the Harlequin Toads or Stubfoot Toads. There are many members of the genus but the majority of them are endangered of becoming extinct. Many species in the genus haven’t been seen in decades. The main culprit of their status is Chytrid Fungus, a deadly fungal pathogen that affects amphibians. Also habitat lose, pollution, and invasive species are also not helping these toads. These toads are often brightly colored and beautiful so it would be shame if they went extinct.
