Blue-tongued lizards eat snails and beetles

Blue-tongued lizards, also known as blue-tongues, are native to Australia and Indonesia. They are the largest members of the skink family and are commonly found in suburban areas, including residential areas of Sydney. They are diurnal, which means they are active during the day, and emerge early in the morning to bask in sunny areas before foraging for food during the warmer parts of the day.

Blue-tongues are omnivores, feeding on a wide variety of plants and animals. They have large teeth and strong jaw muscles, which they use to crush snail shells and beetles. Their diet also includes other insects, frogs, cane toads, small reptiles, birds, small mammals, and fruits.

The blue-tongued lizard's tongue is coated in a sticky mucus, which helps to catch prey by preserving surface tension and drawing the insect back into the mouth. The tongue can also deform itself to produce a thick mucus, which is used to catch prey and as a defence mechanism to ward off potential enemies. When threatened, blue-tongues turn towards the threat, open their mouths wide, and stick out their blue tongues, which contrasts vividly with their pink mouths.

The Eastern Blue-tongue, a type of blue-tongued lizard, is silvery-grey with broad dark brown or black bands across its back and tail. It can grow to almost 600 mm in total length, with about 360 mm comprising its head and body. They usually live in open country with lots of ground cover, such as tussocky grasses or leaf litter, and shelter at night among leaf litter or under large objects like rocks and logs.

They also eat small mammals and birds

Blue-tongued lizards are omnivores, which means they eat both plants and animals. They are native to Australia and Indonesia, and their diet consists of a variety of insects, snails, frogs, Cane Toads, other reptiles, small birds, small mammals, and some plant material, fruits, and vegetation. They are known to be beneficial in urban and suburban areas, as they feed on garden pests such as slugs and snails.

The blue-tongued lizard's diet of small mammals and birds is an important part of its omnivorous nature. These lizards are known to prey on small mammals such as mice, rats, and other small rodents. They also feed on small birds, including sparrows, finches, and other bird species that are typically found in the lizard's habitat.

Blue-tongued lizards are opportunistic feeders, and their diet can vary depending on the availability of food sources in their environment. They are not very agile, so they tend to prey on slow-moving animals, including small mammals and birds that are injured, sick, or trapped.

The lizards' strong jaw muscles and large teeth enable them to crush snail shells and beetle exoskeletons, and these physical attributes also aid in hunting small mammals and birds. They use their blue tongues to sense their surroundings and locate their prey, as the tongue has a "smell" sense that helps them identify potential food sources.

While blue-tongued lizards are known to prey on small mammals and birds, they are also vulnerable to larger predators themselves. In the bush, their major predators include large birds, such as Brown Falcons and Laughing Kookaburras, as well as large snakes like the Eastern Brown Snake and Red-bellied Black Snake. Feral and suburban cats and dogs also pose a significant threat to these lizards, especially the younger ones.

Insects are on the menu

Australian blue-tongued lizards, or Eastern blue-tongued lizards, are omnivores. They eat a wide variety of plants and animals, but insects are a key part of their diet. The blue-tongued lizard is a large species of terrestrial lizard, and its size can make it less agile than other lizards, so it tends to eat slower-moving creatures.

The blue-tongued lizard's diet includes beetles, snails, slugs, and other slow-moving creatures. They have large teeth and strong jaw muscles, which they use to crush snail shells. The lizard's tongue is coated in a sticky mucus, which helps to catch prey and draw it back into the mouth. The tongue can also deform itself to help catch insects. The blue-tongued lizard's diet also includes small mammals, birds, reptiles, and plant material, but insects are a key part of their diet.

The Eastern blue-tongued lizard is native to Australia and can be found in a variety of habitats, including coastal heaths, forests, woodlands, grasslands, and suburban areas. They are diurnal, so they are active during the day, and they tend to live in open country with lots of ground cover, such as tussocky grasses or leaf litter. They shelter at night among leaf litter or under large objects on the ground, such as rocks and logs.

The blue-tongued lizard is a member of the skink family and is the largest species in this family. They are commonly called blue-tongued lizards, blue-tongues, or blueys in Australia. They are also sometimes kept as pets.

As are some plants and fruits

Blue-tongued lizards are omnivores and eat a wide variety of plants and fruits, in addition to insects, snails, frogs, cane toads, other reptiles, small birds, small mammals, and carrion. They are native to Australia and can be found in a range of habitats, including coastal heaths, forests, woodlands, grasslands, and suburban areas. They are diurnal, meaning they are active during the day, and they rely on the warmth of their surroundings to maintain a body temperature of about 30°C-35°C.

The specific plants and fruits that blue-tongued lizards eat are not well-documented, but they are known to eat some vegetation in addition to their animal-based diet. They are considered beneficial in suburban areas, as they eat garden pests such as slugs and snails. Their strong jaw muscles and large teeth allow them to crush snail shells and beetles, indicating that they may also be able to handle harder fruits or plant matter.

The Eastern Blue-tongued lizard, found in New South Wales and the coastal plain of Sydney, is silvery-grey with dark brown or black bands across its back and tail. Individuals in coastal areas may have a black stripe between the eye and ear. This subspecies of the lizard grows to almost 600 mm in length, with about 360 mm comprising the head and body.

The Blotched Blue-tongued lizard is another subspecies, characterized by its dark chocolate brown to black colouration with large pink, cream, or yellow blotches on its back, and a tail banded in the same colours. This subspecies is likely to have a similar diet to the Eastern Blue-tongued lizard, including a variety of plants and fruits.

Overall, while the specific types of plants and fruits that Australian blue-tongued lizards eat are not extensively documented, it is clear that they are an important part of their omnivorous diet and that they play a beneficial role in suburban gardens by eating pests such as snails and slugs.

They are known to eat Cane Toads

Australian blue-tongued lizards, or bluetongues, are the largest members of the skink family. They are commonly found in New South Wales, the coastal plain of Sydney, and the lower Blue Mountains. Bluetongues are known to eat cane toads, which is a cause for concern. Cane toads (Bufo marinus) are an invasive species that are rapidly spreading through tropical Australia. They are highly toxic, and many native predators, including varanid lizards, elapid snakes, crocodiles, and marsupials, have been killed after consuming them.

Bluetongues are large omnivores that may be affected by the toxic toads. Laboratory tests have shown that bluetongues respond strongly to the scent of cane toads, and many of the lizards will attempt to consume them, resulting in poisoning. This has led to a population decline of bluetongues in the Darwin region, where numbers have dropped significantly since the arrival of the toads.

Cane toads pose a significant threat to bluetongues due to their toxic chemical defences, known as bufadienolides. Most native predators in Australia have no evolutionary history of exposure to these toxins, making them vulnerable to poisoning when they consume the toads. The large size of bluetongues may increase their susceptibility to toad poisoning, as they are more likely to ingest a lethal dose compared to smaller lizard species.

The impact of cane toad predation on bluetongue populations is a growing concern for conservationists. The decline in bluetongue numbers has added this lizard species to the list of native Australian predators imperiled by the cane toad invasion. Efforts to mitigate the impact of cane toads on bluetongue populations may include public education, habitat protection, and the development of strategies to control the spread of these invasive toads.

Overall, the consumption of cane toads by Australian blue-tongued lizards is a complex issue that requires further research and conservation efforts to ensure the long-term survival of these lizards in their natural habitat.
