The sand lizard is one of the rarest reptiles in Europe, but wildlife officials are working to establish new populations.
If you are hiking in sandy areas along the Jurassic Coastline, watch for a sandy-brown lizard with dark splotches that is about 20 centimeters long to run across your path as it may be fa a male sand lizard. Alternatively, if you see a sandy-brown lizard with green flanks, you may be seeing a male sand lizard. Their sides become a brighter green during the breeding season, which occurs from April to May because it makes it easier for females to see them. These lizards weigh about 15 grams. Loss of habitat has made spotting one rare, but wildlife officials are starting new populations in many areas of Europe.
5 Incredible Sand Lizard Facts!
- Sand lizards are about 20 centimeters long when mature, and they weigh about 15 grams.
- Sand lizards can be found across much of Europe. A small population exists on the Isle of Coll in the Inner Hebrides in Scotland. Researchers have also found them living in Scandinavia, the Iberian Peninsula, and western areas of Russia, Mongolia, and China.
- Sand lizards burrow during the winter months. This process is called brumation.
- Sand lizards quickly lift each foot off the ground if ground temperatures get too warm to keep their feet from burning. They may also lay on their bellies with all four feet in the air at the same time.
- Sand lizards can live up to 20 years.
Sand Lizard Scientific name
The scientific name for sand lizards is Lacerta agilis. The word “lacerta” derives from the Latin language, and it means lizard while “agilis” is a Latin word meaning mobile, swift or agile. Sand lizards are the only member of this family. It is sometimes called viviparous lizard.
There are at least three sub-species of sand lizards that live in different regions of England. It is hard without scientific testing to determine the difference between those living in the Surrey area, like East Hampshire and West Sussex heathlands, and along the Kentish coast, from those living in the Dorset region around East Hampshire and the West Sussex heathlands. The dorsal stripe on these subspecies may be broken or missing.
The third subspecies lives in the coastal dunes of West Lancashire, Wales, and along the Kentish coast. These lizards are smaller and slimmer. The males are a lighter green than those living in the Surrey or Dorset regions. Unlike those in the Dorset or Surrey area, males may stay green throughout the year. Generally, the dorsolateral stripes on this sub-species are broader and more prominent.
Sand Lizard Appearance
The sand lizard is usually sandy brown. They have dark splotches on their sides that some people believe look like eyes as these markings are typically lighter in the middle and darker around their outsides. These spots often vary in size.
Compared to the European green lizard or the Western green lacerta, sand lizards have a very stocky body. They have incredibly long tails that are often at least 1.5 times as long as their bodies. Like other lizards, this species can lose its tail if it gets trapped somehow.
Males tend to be stockier than females. Males have larger heads with more prominent jaws. The female’s eyes sit about 50% back on the head while the male’s eyes are about 33% back.
Most males have green flanks that turn brighter green during mating season. Scientists believe that this is so that females can see them easier and will find them more attractive. The markings along the flanks are more closely crowded together on the male than on the female.
These lizards lead a solitary life, but you may see two sunning together on a large rock. Often, they are about the same size. During mating season, males become very aggressive. They will fight each other to death.
Sand Lizard Behavior
Sand lizards move around during the day. You will often see pairs of sand lizards basking on top of a sand pile together. They must count on the sun to warm their bodies because they do not generate body heat.
Sand lizards live in burrows underground. They will not come out until they sense that the day is warming up. They stay in their burrows throughout the winter months. When it is time to come out in the spring, males usually leave their burrows before females.
Once they emerge from their burrows in the morning, sand lizards bask in the sun. Scientists believe that they need sunlight to warm their bodies before they have the energy to hunt.
Sand lizards move several meters when foraging for food. Then, they will stop and listen for movement. Once they hear a sound, they will move their heads backward until they locate the source. Then, they pounce on it with their mouths. If the prey gets more than 60 centimeters away, they will ignore it and continue foraging for food.
Sand Lizard Habitat
While this lizard typically lives in dry heathlands, it is very adaptable. The Surrey subspecies must have a gravel or sandy substrate to thrive. The Dorset subspecies also live in cliff-top meadows.
While adaptable throughout much of their lives, they prefer to live in a sloped area. They also need a place that is soft enough that they can create their burrows. Generally, they prefer a mossy area that is at least 30 centimeters deep. They will build their nests and lay their eggs in this area.
These lizards often hunt for their food in grassy areas. Then, return to sandy areas when the sunsets.
Sand Lizard Diet
Sand lizards are carnivores. They prefer to dine daily on grasshoppers, spiders, and insects, but they can survive for long periods if food is not available. Male sand lizards have eaten their hatchlings and the hatchlings of the common lizard if they get hungry.
Sand Lizard Predators and Threats
The main predators of sand lizards are birds of prey, especially kestrels. Another predator is the smooth snake.
This lizard uses several techniques to escape its predators. First, it will stay perfectly still in hopes that the predator does not notice it. If that does not work, then it will try to escape to its burrow. In cases where those two techniques do not work, then it will release its tail. The tail will wiggle on the ground for several minutes, which is usually enough to capture the predator’s attention giving the lizard time to escape. The bite is not poisonous.
Humans are another massive threat to these lizards because of deforestation and the breaking of forests into multiple smaller sections through logging or for housing development. While the International Union for Conservation of Nature considers the species to be of least concern, the Wildlife and Countryside Act of 1981 and the United Kingdom Post-2010 Biodiversity Framework list it as a priority species.
Sand Lizard Reproduction, Babies, and Lifespan
Scientists believe that the female sand lizard chooses her mates. They seem to prefer those that are distantly related. Each female typically mates with several males during March and April, but she will only lay eggs one time each year. If the female is successful in choosing a mate that is more distantly related, then she will usually lay more eggs.
Most nests are near the bare ground on a south-facing slope. Some nests are in sandy areas near marram grass because the female can find warmth and food in the grass.
Baby sand lizards, called hatchlings, must fend for themselves when they are born as the mother does not return to the nest after laying her eggs. Hatchlings reach sexual maturity in about two years.
In their natural habitat, the lifespan most is about 12 years old. Some have a lifespan of about 20 years in captivity.
Sand Lizard Population
No one knows for sure exactly how many sand lizards there are in the world. Scientists believe that the number is severely declining. They feel that there are no remaining sand lizards in North and West Wales, Cheshire, Kent, Sussex, Berkshire, Hampshire, Devon, and Cornwall. They also believe that the population has decreased by over 90% in Merseyside, Surrey, and Dorset.View all 149 animals that start with S
