From a childhood friendship to a lifelong appreciation for toads: Toads, often overlooked due to their grumpy appearance, play a crucial role in controlling insect populations and have unique characteristics that make them valuable allies in gardens and ecosystems.
Priya's love for toads stems from their underdog status and their unique appearance. She was first drawn to them during her childhood when she discovered one in her mom's garden and formed a mutually beneficial friendship with it. Toads, with their grumpy faces and seemingly tough exterior, remind Priya of the underappreciated and overlooked. She went on to study wildlife biology and conservation, focusing on amphibians, and was particularly intrigued by toads. Toads are different from frogs in that they have dry, bumpy skin and are less reliant on water. They can live for 5 to 10 years in the wild, with some species living longer in captivity. Despite their grumpy appearance, toads play a crucial role in controlling insect populations, making them valuable allies in gardens and ecosystems. Priya's fascination with toads began with a simple encounter in her mom's garden and grew into a lifelong appreciation for these often overlooked creatures.
Unique features of Toads: Warts, thicker skin, and toxic secretions: Toads have unique adaptations including warts, thicker skin, and toxic secretions for defense. Some lack teeth and have a bitter's organ, which is a primitive ovary in both males and females. Certain toads have lost their eardrums and do not rely on hearing.
Toads are a type of frog with unique features such as warts, thicker skin, and toxic secretions from their glands. These adaptations serve as a defense mechanism against predators. Unlike frogs, not all toads have teeth. Additionally, toads have an organ called the bitter's organ, which is thought to be a primitive ovary, producing eggs in both males and females. Some toads also have lost their eardrums and do not need them for hearing. Toads' evolutionary history dates back to the cretaceous and cenozoic periods. It's important to note that not all frogs are toads, and their features evolved differently over time. Researchers like Darren Naish have extensively studied toad evolution and its complex branches.
Toads: Hearing, Distinct Features, and Invasive Species: Toads have exceptional hearing abilities, distinct features for species identification, and unfortunately, invasive species like the cane toad have spread to new territories, causing harm to native ecosystems.
Toads are fascinating creatures with unique features that help them thrive in various environments. They have excellent hearing abilities, sensing vibrations through their tympanums, and can distinguish their own species based on differences in color and skull structures. Their eyesight is not exceptional, but they can discern colors. Males are generally smaller than females, and both sexes have distinct features that aid in species identification. Toads have highly ossified skulls, which are used to differentiate species. Unfortunately, invasive toads like the cane toad, which are known for their large size, omnivorous diet, and successful mating strategies, have spread to new territories and wreaked havoc on native ecosystems. In the past, toads were not found in Australia and Madagascar, but invasive species have since established populations on these continents. Cane toads were originally introduced to control sugarcane pests, but they have since become a problem due to their voracious appetite and prolific reproduction.
Managing invasive cane toads: Cane toads are difficult to manage due to their adaptability and beetles avoiding their toxic prey. Unconventional methods like caffeine, euthanization, and exploiting their parotid glands are used. Their diverse habitats add to the challenge.
Controlling invasive species, like cane toads, can be challenging and often requires unconventional methods. Cane toads, which can live in various environments, have proven difficult to manage due to their ability to adapt and the beetles they were intended to eat avoiding their toxic prey. While caffeine has been effective in some areas in reducing their population, methods like euthanization and exploiting their parotid glands for profit are also used. With over 600 species of toads worldwide, their diverse habitats range from burrows to hollows and tree cavities.

Toads' Winter Survival and Social Dynamics: Toads hibernate underground during winter, have arms for grasping, and unique social dynamics
Toads are fascinating creatures with unique adaptations for survival, particularly during winter. Unlike some frog species that can freeze, toads go underground and hibernate to avoid freezing temperatures. Toads have arms, not legs as some may believe, and they use these arms to grasp onto things and interact with their environment. Priya, who has worked with various amphibians, has a special affinity for toads due to their abundant presence and lively breeding behaviors. While they are often found alone during the non-breeding season, they may share burrows with others during hibernation. Toads have intriguing social dynamics, and it's interesting to imagine them having their own underground social gatherings during the winter months.
Toads' Year-Round Sexual Behaviors and Mating Season: Toads exhibit sexual behaviors year-round, especially in warmer regions. During mating season, they can be indiscriminate and competitive, and have unique mating calls.
Toads, particularly those in warmer regions, exhibit active and robust sexual behaviors year-round. Contrary to popular belief, horned lizards, or "horny toads," are not true toads but share similar physical characteristics. During mating season, toads can be quite indiscriminate and competitive, often aggregating in large numbers around females. Males may even attempt to mate with inanimate objects or other males. When a female is ready to breed, she lays her eggs, which are externally fertilized. In some cases, an excessive number of males can drown females by weighing them down. Toads have unique mating calls, such as the American toad's release call, that communicate their gender and intentions. These fascinating amphibians continue to intrigue us with their complex behaviors and adaptations.
Toads with Unique Reproductive Methods: Some toads, like the Pipa pipa and Sonoran Desert toad, have unusual reproductive processes. The Pipa pipa absorbs its eggs into its back and the skin grows over them, while the Sonoran Desert toad produces a hallucinogenic substance on its skin.
Toads in certain families, like the Pipidae and the Bombinatoridae, have unique reproductive methods. For instance, the Pipa pipa, or the "surname toad," absorbs its eggs into its back, and as the eggs develop, the skin grows over them. When the toads are ready to hatch, they emerge as live baby toads. This process can be quite disturbing to some, resembling a horror show. Another interesting fact is that some toads, like the Sonoran Desert toad, produce a hallucinogenic substance on their skin, which some people try to harvest for psychoactive use. However, handling these toads can be dangerous, as the substance can cause discomfort or even harm if it comes into contact with the eyes or mucous membranes. It's important to respect these creatures and their unique adaptations, even if they seem strange or unsettling.
Toads: More Than Just Warty Creatures: Toads have cultural significance and produce psychoactive substances, but it's important to respect their role in nature and avoid dangerous extraction attempts. Some species face extinction due to fungal pathogens, so conservation efforts are crucial.
Toads, specifically the Colorado river or Sonoran Desert toad, have been used for centuries by indigenous cultures for their psychoactive properties. These toads produce a substance called DMT, which can lead to profound experiences. However, attempting to extract this substance on your own can be dangerous and disrespectful to the culture and history. In popular culture, there are conflicting portrayals of toads, with some promoting negative stereotypes. In reality, toads have warts to protect themselves and are not sources of diseases. Some toad species are facing extinction due to the chytrid fungus, a fungal pathogen that has devastated amphibian populations worldwide. Conservation efforts are underway to protect and preserve these vulnerable species. Overall, it's important to respect the cultural significance of toads and to appreciate their role in natural ecosystems.
Impacts on Toad Populations: Toad populations face threats from natural diseases, human-induced issues, and predation by birds and snakes.
The history of toads includes both natural threats like fungal diseases and human-induced issues such as the use of African clawed frogs for pregnancy tests, which led to the spread of a deadly fungal pathogen. These factors, along with predation from birds and snakes, have impacted toad populations. For instance, the Asian market trade of African clawed frogs, which were used as pregnancy tests and then discarded, led to the spread of a fungal disease that affected native toad species. Predators like crows and raccoons also pose threats to toads by eviscerating them and consuming their insides. Despite these challenges, toads continue to be an essential part of ecosystems and have even found a place in pop culture, as seen in movies like "Attack of the Killer Toads."
Exploring the Lives of Toads: From Land to Ponds: Toads live mostly on land, breed in ponds, and can be attracted to backyards with proper habitat
Toads and frogs share similar life cycles, but the length of their lives varies by species, typically ranging from 5 to 10 years. Toads spend most of their time on land, coming to ponds only during breeding seasons to attract mates. Some toads call to attract mates, while others use leg waving. To create a backyard haven for toads, one can bury pots halfway to create tunnels or purchase toad homes. If you're interested in learning more about toads and their habitats, consider checking out the Amphibian and Reptile Conservancy or the Gastropod podcast.
Toads' Unique Behaviors and Medical Potential: Toads attract mates through distinct movements, lay numerous eggs, and have toxins studied for medical uses as anti-inflammatory agents, cardiac regulators, and anticancer agents. Solitary creatures, they defend themselves by peeing on intruders.
Toads are fascinating creatures with unique behaviors and potential medical applications. They attract mates through distinct movements and lay a large number of eggs, some of which hatch into adorable toadlets. Toad toxins are being studied for their possible uses as anti-inflammatory agents, cardiac activity regulators, and anticancer agents. Toads are often solitary creatures, coming together only during breeding seasons, and they defend themselves by peeing on intruders as a defense mechanism. Despite their warty appearance, many people find toads to be cute and expressive.
Handling Toads with Care and Their Role in History: Be cautious when encountering toads, especially poisonous ones. Historical beliefs linked toads with witchcraft and poisoning.
Toads, especially poisonous ones like the cane toad, should be handled with care. If you find a toad in the woods and it pees on you, give it some water instead. The most poisonous toad may be the cane toad, but there are other toxic species as well. Toads have played a significant role in folklore and magic spells throughout history. In medieval times, they were believed to be associated with witchcraft and poisoning. There is no humane way to get rid of cane toads in large numbers, and their movements are generally limited, but some species may travel several miles to find food or mates.
Toads' astrological and chemosensory navigation skills: Toads in montane habitats use a combination of astrological and chemosensory cues to navigate back to their home ponds, demonstrating their impressive navigational abilities.
Certain toads, specifically those in montane habitats, possess a remarkable ability to return to their home ponds using a combination of astrological and chemosensory cues. This discovery, though not widely documented in literature, is a testament to their incredible navigational skills. Another interesting aspect discussed was the varying mating calls of different toad species, with some, like the American toad, producing soothing trills, while others, such as the Fowler's toad, emit calls reminiscent of distress or horror. Despite the admiration for these creatures, there were mentions of challenges, such as the discomfort of frogging at night and the potential aggression of toads. Overall, the conversation showcased the unique characteristics and intrigue surrounding these amphibians.
Toads' Impressive Poop: Toads produce large logs of poop, up to a third to a half of their body length, requiring a second toilet in human terms.
Learning from this episode of Ologies is the fascinating fact about toads and their large poop. Toads have the ability to produce logs that are a third to a half of their body length. This was described as a crazy and impressive sight, and the speaker even shared some YouTube videos to prove it. The volume of their poop is so large that it would require a second toilet in human terms. Despite the focus on this unusual topic, the speaker expressed her love for toads and encouraged listeners to follow Priya Nanjappa on social media for more wildlife-related content. The episode also highlighted the speaker's various science projects and collaborations, including her appearances on Bring Child, Did I Mention Invention?, and Innovation Nation.
