What You'll Learn
Physical appearance of frogs and cane toads
Frogs and cane toads may look similar at first glance, but upon closer inspection, there are a few key physical differences that can help you tell them apart. Here are some features to look out for:
- Size: Frogs are generally smaller than cane toads. Most frogs have a size range of 1-4 inches, while cane toads can grow up to 6-9 inches or even larger.
- Body shape: Frogs have a more slender and streamlined body shape compared to cane toads. Frogs typically have a slender waist and their bodies taper towards their hind legs. On the other hand, cane toads have a rounder and bulkier body, lacking the slim waistline of frogs.
- Skin texture: Frogs have smooth, moist, and slightly slimy skin, which helps them to absorb water through their skin. On the other hand, cane toads have rough and bumpy skin with raised warts. These warts are larger and more pronounced in cane toads, giving them a distinctive textured appearance.
- Coloration: Frogs often display a wide range of vibrant colors and patterns on their skin, including various shades of green, brown, and even bright hues of red and blue. Cane toads, on the other hand, usually have duller and more uniform colors like shades of brown, gray, and olive. Their skin color can blend in with their surroundings, making them less visually striking compared to frogs.
- Eyes: The eyes can also provide a clue in distinguishing between frogs and cane toads. Frogs generally have large, round, and bulging eyes that protrude from the sides of their head. Cane toads, on the other hand, have smaller eyes that are positioned closer to the top of their head. Additionally, cane toads have a yellowish horizontal pupil, whereas frogs typically have a round pupil.
- Parotoid glands: Perhaps the most distinctive feature of cane toads is the large, swollen glands located on the back of their head, behind their eyes. These glands, known as parotoid glands, secrete a toxic substance when the toad is threatened. Frogs do not have these prominent glands on their head.
By paying attention to these physical features, you can develop a keen eye for distinguishing frogs from cane toads. Remember to consider multiple characteristics and use them in combination to make a positive identification. If in doubt, it is always best to consult local field guides or seek expert advice to ensure accurate identification.

Vocalizations and calls of frogs and cane toads
One of the best ways to tell the difference between frogs and cane toads is by their vocalizations and calls. Frogs and cane toads use different sounds to communicate with each other and attract mates. By learning to recognize these vocalizations, you can easily identify whether you are dealing with a frog or a cane toad.
Frogs are well-known for their melodious and soothing calls. Their vocalizations vary greatly among different species but they generally produce sounds that are pleasant to the ears. Frogs use their calls to attract potential mates and establish their territories. Their calls can range from soft chirps to loud croaks, depending on the species. Some frogs sing in harmony, creating an enchanting chorus that can be heard from a distance.
On the other hand, cane toads produce loud and harsh vocalizations. Their calls have been described as sounding like a loud, vibrating engine or a continuous buzzing sound. These calls are quite unique and distinct from the melodious calls of frogs. Unlike frogs, cane toads do not use their vocalizations for courtship but rather as a warning signal or defense mechanism. When threatened or distressed, cane toads emit a high-pitched distress call that can be quite startling.
Another key difference between the vocalizations of frogs and cane toads is the frequency and duration of their calls. Frogs tend to produce shorter and more sporadic calls, especially during breeding seasons. Cane toads, on the other hand, often produce longer and continuous calls, which can be heard throughout the night. The continuous buzzing sound of cane toads is one of the reasons why they are considered a nuisance in some areas where they have been introduced.
It is important to note that while frog calls are a beautiful part of nature, cane toad vocalizations should be treated with caution. Cane toads are invasive species and their presence can have negative impacts on native wildlife. It is crucial to differentiate between the two and take appropriate action if cane toads are discovered.
In conclusion, the vocalizations and calls of frogs and cane toads can provide valuable clues in distinguishing between these two species. Frogs produce a wide variety of pleasant, melodic calls used for courtship and territorial defense, while cane toads emit loud and harsh vocalizations as a warning signal. By familiarizing yourself with these distinct sounds, you can easily identify whether you are dealing with a frog or a cane toad and take appropriate action accordingly.

Habitat preferences and behavior of frogs and cane toads
Frogs and cane toads are two amphibian species that can sometimes be mistaken for one another. While they may have similar physical appearances, there are some key differences in their habitat preferences and behavior that can help you distinguish between them.
Habitat Preferences:
Frogs:
- Frogs are typically found in moist habitats such as forests, wetlands, and marshes.
- They prefer areas with ample vegetation and water sources like ponds, streams, or rivers.
- Different species of frogs have specific habitat preferences, but they generally require a body of water for reproduction.
Cane Toads:
- Cane toads are more adaptable and can be found in a wider range of habitats, including urban areas and agricultural fields.
- They are often found near bodies of water, but can also survive in drier environments such as grasslands and scrublands.
- Cane toads are known for their ability to thrive in disturbed habitats and can be highly invasive in some regions.
Behavior:
Frogs:
- Frogs are generally nocturnal, meaning they are most active at night.
- They are known for their jumping and leaping abilities, and can move quickly when threatened.
- Frogs have unique mating calls, and males often produce distinct vocalizations to attract females during the breeding season.
Cane Toads:
- Cane toads are mostly nocturnal as well, but can also be active during the day.
- They have a characteristic slow and waddling walk, and are not capable of jumping or hopping like frogs.
- Cane toads are poisonous, and have large parotoid glands on their shoulders that secrete toxic substances as a defense mechanism.
- Unlike frogs, cane toads do not produce distinctive mating calls. They rely on visual cues to find mates.
By considering these differences in habitat preferences and behavior, you can identify whether you are dealing with a frog or a cane toad. It is important to note that cane toads are not native to many regions and can have detrimental effects on local ecosystems. If you are uncertain about the identity of an amphibian, it is always best to consult with a local expert or naturalist who can provide additional guidance.

Recognizing the difference between frog and cane toad tadpoles
If you live in an area where both frogs and cane toads are present, it is important to be able to distinguish between their tadpoles. While both start their life in the water, they have distinct characteristics that can help you to tell them apart. Being able to recognize the difference is crucial, as cane toads are an invasive species and can be harmful to the local ecosystem. In this article, we will guide you through the key features to look out for when trying to identify frog and cane toad tadpoles.
Body Shape:
The body shape of frog tadpoles is usually slender and elongated. They have a streamlined body that helps them swim faster, with a rounded tail. On the other hand, cane toad tadpoles have a stocky and robust body. Their body shape is more squat, and their tail is shorter and stubbier than the frog tadpoles.
Coloration:
Frog tadpoles tend to have a transparent, almost translucent body with a hint of green or brown coloration. Their intestines are often visible through their skin. In contrast, cane toad tadpoles have a darker, more solid coloration. They can range from a dark brown to black, with a smaller possibility of having some lighter spots.
Eyes:
The eyes of frog tadpoles are located on the sides of their heads, and they are relatively smaller in size compared to their body. Cane toad tadpoles, on the other hand, have larger and protruding eyes. These eyes are located on the top of their heads and tend to be more noticeable.
Movement:
The swimming behavior of these two tadpoles can also provide some clue about their identity. Frog tadpoles often swim in a smooth and gliding motion, propelling themselves forward with ease. Cane toad tadpoles, on the other hand, tend to have a slower and more jerky swimming motion, perhaps due to their stockier body shape.
Behavior:
While both tadpoles are aquatic, there can be differences in their behavior. Frog tadpoles are generally more active and exploratory, often seen swimming around in search of food or shelter. Cane toad tadpoles, however, are typically less active and tend to stay near the bottom of the water, not venturing too far from their initial location.
Remember, it is important to handle tadpoles with care and avoid introducing cane toads into new areas if possible. If you're unsure about the identification, it's always a good idea to consult with local wildlife authorities or herpetologists for further assistance.
By paying attention to these key characteristics, you can become proficient at recognizing the difference between frog and cane toad tadpoles. By being aware of the presence of cane toads and reporting any sightings, you can help protect your local environment and keep the balance between native species intact.
