Aegean wall lizards are known for their odd eating habits. The species is known to feast on other aegean wall lizards’ eggs, and will sometimes bite the tails of other adults. But cannibalism had never been seen before. Studying cannibalism in the wild is difficult because it relies on interactions between individuals.
In the new study, published today in Current Biology, a team of researchers from the University of California, Santa Cruz and the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, set out to find out if the wall lizard was cannibalizing its own eggs. To do this, the researchers collected eggs from three different species of wall-lizard, as well as from a third species that had not previously been studied.
They then fed the eggs to a group of juvenile walllizards, which were then allowed to incubate them for up to two weeks. After incubation, they were returned to the nest to feed on the newly hatched hatchlings. All three species were found to have cannibalized their own eggshells, but only one of the three had been observed to eat the egg of another individual.

Are lizards cannibalistic?
Competition for resources has to be fierce in order to make the tiring life of a tarantula worthwhile. Tarantulas are not the only arachnids that eat other arthropods. Some spiders, such as orb weavers, eat ants and termites, and some mites eat caterpillars and other insects. However, most spiders do not eat their prey whole.
Instead, the prey is chewed up and swallowed whole by the spider, which then regurgitates the contents of the stomach into its mouth. The spider then swallows the remainder of its meal, leaving the rest in its stomach.
Do lizards eat small lizards?
They will also eat smaller lizards and baby rodents. Many small lizards supplement their diet with fruit, insects, and small animals. Lizards can be found in almost all habitats, including deserts, grasslands, savannas, forests, marshes, swamps, lakes, ponds, rivers and streams.
Do lizards eat their own babies?
Unless the parent has a way to tell who its own offspring is, it may eat its young by mistake, which is good for the parents because they get a meal. In other words, if you are a parent and your child is not your own, then you can’t eat it.
You can, however, give it to someone else who is your kin, and that person can then eat the child. This is called “kin recognition” and it is one of the most important aspects of kinship. If you don’t know who your children are, you have no way of knowing if they are yours or not, so you should be very careful about who you give food to.
Why do lizards bite each other’s tails?
It turned out to be something else. What looks like a fight between two lizards, is actually a form of lizard courtship, a lizard love-making ritual.
Lizards have been known to form courtships with each other for thousands of years, but this is the first time it’s been documented in the wild, according to a new study published in Current Biology.
The study was conducted by a team of researchers from the University of California, Santa Cruz, and the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.
Are lizards scared of humans?
They seem to be afraid of humans; they will run away from predators if they feel threatened. Taking action to ensure your home is safe is one way to manage your fear. If you have a fear of dogs or cats, you may want to consider adopting a dog or cat from a shelter or rescue organization.
How do you tell if a lizard is a boy or a girl?
An ultrasound can easily determine a reptile’s gender and can also help to tell if the reptile is reproductively active. It is not painful and can be done in most species that are large enough.
