Horny Toads - The Desert's Miniature Lizards - Animal Corner (original) (raw)

The Horny Toad, is quite a misleading name for an animal that, despite their appearance, is neither a toad, or even an amphibian. They are often mistaken for toads however, due to their flattened, rounded bodies. They are also known as the Horned Lizard, which is more accurate, and are found throughout North America and Mexico.

Scientifically, these lizards belong to the genus ‘_Phrynosoma‘, which belongs to the family ‘Phrynosomatidae‘ in the suborder ‘Iguania_‘. There are 21 species of horned lizards, and a few sub species, but some continue to have contested taxonomy and the classification may yet change again. Regardless, each species has its own unique characteristics, but they all share the iconic horned appearance.

Appearance & Characteristics of Horny Toads

Horny Toads (Horned lizards) are small creatures, with very capable defences. Depending on the species, their size can range from 2.5 to 6 inches from snout to vent (SVL). Their weight varies, depending on the species as well as their age, but ranges in across species between 5 to 60 grams. Here are some examples:

• Texas Horned Lizard (Phrynosoma cornutum): Adults typically weigh between 25 to 50 grams (0.88 to 1.76 ounces).
• Greater Short-horned Lizard (Phrynosoma hernandesi): This species, being one of the larger horned lizards, can weigh up to 60 grams (2.1 ounces) or more in some cases.
• Coast Horned Lizard (Phrynosoma coronatum): Adults of this species usually weigh in the range of 20 to 40 grams (0.7 to 1.4 ounces).
• Flat-tail Horned Lizard (Phrynosoma mcallii): Being a smaller species, adults typically weigh between 5 to 15 grams (0.18 to 0.53 ounces).
• Pygmy Short-horned Lizard (Phrynosoma douglasii): As the name suggests, this is one of the smaller species, with adults weighing between 5 to 10 grams (0.18 to 0.35 ounces).

Their most distinctive features are the horn-like structures on their heads, which serve both as a defence mechanism and a unique identifier.

Their colouration, which can range from sandy browns to vibrant reds, serves as excellent camouflage in their natural habitats. Their bodies are covered in scales, some of which are modified to form spiky defences against predators. Despite their intimidating appearance, horned lizards are quite docile and rely more on their camouflage and other defence mechanisms than on aggression.

Why Are They Called Horny Toads?

The name ‘Horny Toad’ is a colloquial term that stems from their toad-like appearance. Their flattened bodies and blunt snouts resemble that of a toad. The term ‘horny’ is a nod to the horn-like structures on their heads. These animals are not toads though, and are not even related. They are lizards of the reptilia class and it’s really important for any potential pet owner to understand this.

They are also sometimes called ‘horntoads’, and commonly called ‘horned lizards’ which is a more accurate descriptor of what they are.

Distribution – Location and Habitat

Horny toads are primarily found in North America. They are mostly desert dwellers and thrive in arid and semiarid regions. These environments provide them with the perfect camouflage and a diet rich in ants. States like Arizona, Texas, and New Mexico are particularly rich in horned lizard diversity. They prefer open habitats, such as grasslands, deserts, and dunes, where they can easily spot predators and prey.

One species – Greater Short-Horned Lizard (Phrynosoma hernandesi) can be found as far north as Canada, in Saskatchewan and Alberta, with a range that stretches as far south as Mexico. This species is the most widely distributed lizard in North America, and lives in wide range of different habitats. Two other species can also be found as far north as Canada, particularly around the Rockies.

The Lifestyle & Behaviour of The Horny Toads

Horny toads lead a diurnal lifestyle, being most active during the day. They are solitary creatures and often spend their days basking in the sun or hunting for food. Though they tend to avoid the intense heat of midday by seeking shade or burrowing slightly into the ground. They only really come together for mating and can be quite territorial.

When threatened, they have a range of defence mechanisms. They can puff up their bodies to appear larger, run in short bursts to confuse predators, or remain perfectly still, relying on their camouflage.

At least 8 species have even developed the ability to squirt blood from their eyes as a deterrent against predators. They usually reserve this strategy for use against types of canid and cats though, as it has a particularly foul taste to these animals. The primary defence mechanism for all species, is their camouflage and stillness.

Horny toads have competent burrowing skills, and will often create small depressions either to hide, rest or manage temperature. Some species in North America that live in colder, northerly states and Canada, may hibernate in winter, but those in the warmer, arid ranges do not.

Diet & Nutrition of The Horny Toads

Ants are the primary diet of horny toads, especially harvester ants which make up around two thirds of the food they eat. They use their sticky tongues to capture these ants, consuming them in large quantities. Their hunting strategy is more about patience than pursuit. They will often wait near ant trails, ambushing their prey as they pass by. This diet is rich in formic acid, which may contribute to their unique blood-squirting defence mechanism.

Other insects that horny toads eat include grasshoppers, termites and beetles but it does vary across species depending on the availability of prey species in their specific range.

Predators & Threats to The Horny Toads

Natural predators of the horned lizard/horny toad include birds of prey, snakes, and larger mammals. However, their unique defence mechanisms, such as their often spikey skin and ability to squirt blood, deter many potential threats. This blood-squirting behaviour is believed to confuse predators and deter them from eating the lizard. The taste of the blood ejected is also unappealing to many predators.

Despite this defence mechanism, there are many threats that they face, as eggs, juveniles and as adults. In some sense of twisted irony, one of their main predators in the egg, are ants that will raid their nests, and eat the eggs. Roadrunners and crows will also prey on the egg or juvenile horny toads, as will rats, racers and whipsnakes.

Adults have their own predators to look out for. From the air, they have to look out for hawks and owls, and from the ground, coyotes, foxes as well as domestic dogs and cats will often prey on these little lizards.

These little lizards also have many environmental and human threats. Habitat loss from human expansion, and due to climatic and environmental changes has decimated species in some areas. Their mating cycles are quite sensitive and the reduction of suitable nesting grounds can put real pressure on successful reproduction.

They are also threatened by the loss of their food supply, as their main prey – the harvester ant – is targeted by pesticides, and decimated by invasive fire ant species.

The Horny Toads Reproduction

Horny toads reproduce by laying eggs. The number of eggs, their size, and the duration of incubation can vary depending on the species. Typically, after mating in the spring, the female will lay her eggs in a burrow or under rocks. These eggs will then hatch after several weeks, bringing forth the next generation of horned lizards.

The mating season for horny toads typically begins in spring and can extend into early summer. The exact timing may vary depending on the species and the region they inhabit. Male horned lizards will first establish and defend territories, which they mark using a gland located near the cloaca. They will then engage in charismatic displays to attract females, which can include push-ups, head-bobbing, and colour changes.

Once a female enters a male’s territory, the male will approach her and engage in a courtship ritual. The females are not always receptive, but when they are, mating will occur.

Horny toads are oviparous, meaning they reproduce by laying eggs. After mating, the female will search for a suitable nesting site, typically in sandy or loose soil. She will then dig a burrow or nest chamber and deposit her eggs. The number in a clutch varies between 3 to 30 depending on the species.

Like most reptiles, the eggs receive no parental care at all. They are unattended by the female, and incubate for between 5 to 9 weeks before hatching from their eggs. They are born fully formed and are miniature replicas of the adults, albeit with softer and more vulnerable bodies. From the minute they are born they are independent.

Lifespan of The Horny Toads

On average, horned lizards can live up to 5-8 years in the wild, although this can vary based on species and environmental factors. They go through several life stages, starting as eggs, then hatchlings, juveniles, and finally, at around 2 years old they become sexually mature adults.

Population and Conservation

Most species of horny toad (horned lizard) have stable populations according to the IUCN. Some – including the Sonoran Horned Lizard – have yet to be assessed or have deficient data to assess the stability of the population. Then there are those, such as the San Diego Horned Lizard and Flat-tailed Horned Lizard that have a declining population, the latter of which is considered to be Near Threatened.

These listings may show little cause for alarm, but in some areas populations have declined dramatically. In Oklahoma for example, population levels are believed to be in great decline, and organisations have petitioned to have the species added, at least locally, to the endangered species list. In Canada, the Pygmy short-horned lizard is considered to be at risk by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC).

Conservation efforts, including habitat preservation and protective legislation, are in place in various regions to help protect these unique creatures.
