There is a pale stripe on the back and a white belly with one dark spot. These toads are large and can grow to 7 inches (17.5cm) with females being larger than the male. Asiatic toads (Bufo Gargarizans) are common throughout China, parts of Russia, and southern Japan.
The common toad (Bufo bufo) lives up to 40 years, but most toad species live about 5 to 10 years. However, the potency and delivery of this venom vary significantly between species. While all toads have the capacity to secrete toxins as a defense mechanism, not all pose are toads poisonous a serious threat to humans or even larger animals.
Fowler’s Toads emit a nasal “waa” or bleat, often likened to the sound of sheep. Eastern American Toads have a musical, extended trill that can last up to 30 seconds. These sounds are typically used by males to attract mates and assert their territory, creating a variety of unique calls across species. Yes, all toads, including backyard toads, are poisonous in all stages of their lifecycle. Also known as the bufo toad (a legacy of its former Bufo genus classification), the Cane Toad is a large amphibian native to South and Central America. Introduced to various parts of the world, including Australia and Florida, as a pest control measure (ironically, it proved largely ineffective), it has become an invasive species.
In humans, toad poison can cause nausea, vomiting, abdominal discomfort, and potentially dangerous heart rhythm abnormalities. Symptoms of toad poisoning in dogs can appear within minutes to hours, depending on the amount of toxin ingested and the size of the dog. The toxic compounds in toad venom are complex, but many are steroids similar to digoxin, a heart medication. When absorbed into the body, these toxins can disrupt normal heart function, leading to potentially life-threatening arrhythmias. Other components can affect the nervous system, causing seizures and other neurological issues. All toads secrete a toxic substance through their glands, which are on the skin.
These toads live underground until the monsoon season, when they rise above the ground. They are most active at night and may hide in burrows and between rocks during daylight. Toads face a variety of predators, including raccoons, snakes, large fish, snapping turtles, and birds of prey like hawks and owls. A standard-sized toad can eat around 3,200 insects per season, making them great for garden pest control. When they are tadpoles, they are herbivores and eat soft plant material or algae.

Wild Relatives: The harpy eagle
Some animals have developed immunity to the toxins produced by poisonous toads and can safely consume them without any harmful effects. All toads are poisonous, secreting toxins through their skin, particularly from the parotoid glands behind their eyes. Adult toads generally prefer moist, open habitats like fields and grasslands.
- Read on to learn more about toads, including the characteristics that separate them from frogs.
- So, it’s good to be aware of what toxic toads are in your area or where you travel and what to do if you suspect your pet has had a run-in with one.
- They have a kidney-shaped gland just behind their golden eye with white glands on the legs, all of which produce toxic secretion.
- However, some species eat reptiles, small mammals, and even other amphibians.
- Every toad species utilizes a specific toxin or toxin blend as a primary defensive mechanism in the wild.
What toads are poisonous to humans?
They can change color as a response to light and heat changes with females being larger than the male. European green toads (Bufotes Viridis) are found in mountainous areas, deserts, urban areas, and other habitats in Europe, from France to Western Russia. They live in a range of habitats from open grasslands to forests and backyards.
Identifying the Culprits: The Most Toxic Toads
These toads are common in Japan, living in a variety of habitats from mountainous areas to lowland areas. The toxin can also cause skin and eye irritation in humans who handle the toads. Cane toads breed along the edge of freshwater ponds and lakes between March and September, and the eggs look very similar to native toad eggs.
Toxicity to Humans
They have parotid glands behind their eyes, which are responsible for secreting a milky substance known as bufotoxin. This cocktail of chemicals acts as a defense mechanism against predators. In cases of severe toad toxin poisoning, medical treatment may be necessary to manage symptoms such as nausea, vomiting, and seizures. There is no specific antidote for toad toxins, so supportive care is typically recommended.
If your pet licked the toad, you (or your vet) should wash out the mouth thoroughly for 5 minutes, with the hose pointed toward their nose. Some pets with toad toxicity develop low blood pressure, which can lead to kidney failure if it is prolonged. Poisonous toads can be found in a variety of habitats, including urban areas, so it is important to be cautious when encountering them in any environment. So instead of snatching their prey with a powerful bite, toads rely on their long, sticky tongues to catch a meal, according to the American Museum of Natural History. Once they have captured their prey, they swallow it down hole, unable to chew it because they don’t have teeth.
Avoid Contact with Sensitive Areas
American toads can live in a variety of habitats near water, and this can even include your yard. They are dark in color, varying from brown to olive green to gray, and their skin is covered in spots and bumps. Warts are caused by a virus that can only be transferred to humans from another human, not from toads.
Since we haven’t bred out their natural predatory instincts, it’s less likely that cats will respond to a trained cue like “leave it” if their prey drive kicks in. Give it a shot by using the “leave it” techniques linked in the dog section above. Toads are thin-skinned and can easily be harmed or killed by chemicals in everyday products harmless to us. So, make sure not to handle a toad if you have these on your hands. Their belly is cream to yellow with small tubercles on their backs. Gulf coast toads (Incilius Valliceps) are native to eastern and southeastern Mexico and Central America.
What Worms Does Ivermectin Kill In Dogs
In the case of the American toad, the bufotoxin is relatively mild compared to that of more potent toads like the Cane toad or Colorado River toad. Symptoms of toad poisoning in dogs include profuse drooling, pawing at the mouth, vomiting, disorientation, bright red gums, erratic behavior, seizures, and elevated heart rate. If you suspect your pet has ingested a toad, seek immediate veterinary care. Symptoms of toad poisoning in pets include excessive drooling, vomiting, incoordination, seizures, and heart abnormalities. The severity of toad poisoning depends on the species of toad, the amount of toxin ingested, and the size of your dog. It’s crucial to seek veterinary care immediately if you suspect your dog has eaten a toad.
Handling can cause stress to the animal, disrupt their natural behavior, and potentially expose them to diseases they’re not equipped to fight off. The single most important thing you can do after touching an American toad (or any amphibian or reptile) is to wash your hands thoroughly with soap and water. This simple act will effectively remove any bufotoxin residue and eliminate the risk of Salmonella transmission. Beyond the bufotoxin, another concern with handling amphibians like American toads is the potential for Salmonella transmission. Reptiles and amphibians are known carriers of these bacteria, which can cause salmonellosis in humans.
Some toads are more poisonous than others, secreting higher amounts of toxic when they are threatened. The most important poison in newts and salamanders is tetrodotoxin (TTX), one of the most dangerous toxins known to man. It acts on the nervous system and can lead to muscle paralysis. TTX-containing newts are found in Oregon, California, and southern Alaska.
Which toad is dangerously poisonous??
Immediately flush your eyes with clean water for at least 15 minutes. If you experience any irritation or vision changes, seek medical attention. Yes, all toads have toxins, though the potency varies significantly between species. Removing standing water, debris, and other potential hiding places can help reduce the toad population in your yard. You can also use a salt-water spray (1 part salt to 4 parts water) in areas where you don’t want toads, but be careful not to spray plants. This is the smallest toad species in North America and grows to 1.30 inches (3.3cm).
Proper handling and hygiene practices are essential when dealing with toxic amphibians. While many species of toads do produce toxins as a defense mechanism, not all toads are considered toxic to humans. Some toad species are completely harmless and do not secrete any toxins. Another trend is the rise in toad-related injuries among children and pets.
