About the American Toad
The American Toad, a fixture in North American gardens, woodlands, and fields, is often a child’s first introduction to the world of amphibians. Although they might seem common and unassuming, these toads are complex creatures with specific needs and behaviors that make them both fascinating and vital to their ecosystems. Whether kept as low-maintenance pets or appreciated in the wild, understanding the American Toad’s way of life is crucial to ensuring its survival and continued cohabitation with humans.
Size
American Toads are moderately sized amphibians, generally ranging from 2 to 3.5 inches in length when fully grown. Females are often larger than males, sometimes noticeably so, and have a more rounded body shape. Their size makes them quite noticeable when hopping around gardens and parks, especially during wet evenings.
Unique Features
One of the American Toad’s most distinguishing features is its warty skin, which is actually a misnomer since true warts are caused by viruses. These “warts” are actually glands that produce and secrete toxins, which deter predators. The most noticeable of these glands is the parotoid gland located behind the eyes. Additionally, these toads have a pronounced and robust vocal sack, allowing males to produce trilling calls during the mating season.
Behavior and Temperament
American Toads are nocturnal, preferring the cooler and damp conditions of the night to hunt for food and explore. While they might seem slow and docile, they can move quickly when threatened or chasing after a potential meal. Their temperament is generally calm, and they are not known to be aggressive. However, when threatened, they might puff up to appear larger or secrete a mildly toxic substance from their glands as a defense mechanism.
Handling
Handling should be minimal with the American Toad. When necessary, ensure your hands are wet to prevent their skin from drying out, and avoid having any lotions or chemicals on your hands, as their skin is highly permeable. Prolonged or frequent handling can cause them undue stress, leading to potential health issues.
Diet & Nutrition
Being insectivorous, the American Toad has a diet primarily consisting of insects like beetles, ants, spiders, slugs, and worms. Their sticky tongue quickly shoots out of their mouth, catching their prey off-guard. In captivity, a varied diet of crickets, mealworms, and earthworms can be supplemented with vitamins and minerals to ensure their nutritional needs are met.
Temperature
American Toads are hardy animals and can tolerate a range of temperatures. However, if kept in captivity, the ideal temperature range for their enclosure would be between 60°F to 70°F. In the wild, they hibernate during the colder months by burrowing deep into the ground below the frost line.
Humidity
These toads thrive in moderately high humidity. If in captivity, a humidity level of 60-70% is recommended. This can be achieved by misting their enclosure daily and providing a water dish for them to soak in.
Lighting
In the wild, American Toads are exposed to natural sunlight, but they’re primarily nocturnal, so they aren’t as dependent on UVB lighting as some reptiles. However, if kept indoors, providing a regular day-night light cycle can benefit their natural behavior and well-being.
Common Health Issues
Like other amphibians, American Toads can suffer from a range of health problems, often stemming from poor diet or unsuitable living conditions. Metabolic bone disease, fungal infections, and parasites can ail them. Ensuring a clean habitat, proper diet, and minimal stress can help mitigate most health risks.
Breeding
Breeding typically takes place after the first warm rain of the spring. Males call out to attract females with a high-pitched trill that can last up to 30 seconds. Once a male finds a partner, amplexus occurs, where the male grips the female to fertilize the eggs as she lays them.
Mating Habits
During the breeding season, males often congregate in ponds, waiting for females. The competition can be fierce, leading to some males attempting to mate with anything that moves in the water, including other males or even fish. Once a female is ready, the male clasps her in the amplexus position. The female then lays long strings of eggs, which the male fertilizes externally. The eggs then hatch into tadpoles, which will eventually metamorphose into young toads.
