Slow worms, and other lizards

Slow worms, anguis fragilis, are legless lizards, about nine inches/24cm long. I can only remember seeing one in the UK, where it seems to be getting rarer. Here in Normandy a couple of weeks ago I saw this slow worm in our garden, moving very casually through some grass. This is the fourth time I have seen one here, each time in a different corner of a half acre garden, so I think I can assume that there is a colony living here.


Looking at it clearly, it is easy to see that it is a lizard, not a snake. Its head is lizard shaped, and although it moves like a snake, it does so because any creature with no legs and a long body has to move that way. It flickers its tongue, but so do most lizards. Despite their name, they can move quite fast, and can disappear into a hole or under rocks pretty rapidly.


We usually find common lizards  in the garden at some time during the year, but not very many. We are not only fairly far North, but also our area is quite high above sea level, so we do not have as many as one would find around the Baie de Mont St Michel locally, and certainly not the numbers of individuals and different speciies that are common further south. The other reptile that we have is the salamander, and there is more about that here.


I also saw a quite large lizard, about 8 inches/22cm on a path by the sea on Morbiham, Brittany, a few weeks ago, but is scampered off into the undergrowth. It emerged a few minutes later, but imposible to get near. This photo is an enlarged detail, and not very good, but the best I could do. I do not know what species it is.

Salamanders and toads


One of the creatures we used to see quite often – sometimes alive, often as roadkill – was the fire salamander. This is a form of plump lizard, with a short thick tail, and is very slow moving. It is black, with yellow (broken) stripes down its length. Black and yellow usually serve as a warning that the creature concerned is either dangerous, unpalatable to eat, or both, and this is so with the salamander, which has venom glands all along its body.
Over the years we saw fewer and fewer, and none at all for the last several years. However, this year when digging around the base of a hedge, I inadvertently came across the one shown in the photo above. It does not appear that black, because it is still covered with earth. The salamander is mostly nocturnal, and spends the days underground, usually in a hole previously occupied by a mouse or other rodent. They are harmless to people (unless you ate one, which I don't recommend and have never seen a French recipe for doing so), but not harmless to invertebrates such as snails and worms: see this video of a salamander eating a worm.
They are supposed to be still quite common throughout Europe, but I have never seen one in England. Nor have I ever seen a slow worm in the UK, although they are supposed to be common. I have seen two in our Normandy garden in the last year, which is very encouraging.
We also used to have a fair number of toads. In fact, our elderly neighbour used to laugh at me for going into the garden with a torch in the evening looking for them. One regular visitor was about six inches/14 cm, and we called him Bertie, because he looked like the young King Edward VII when he was Prince of Wales. The first time we met Bertie was at dusk one August, as we were finishing dinner and the last of a bottle of wine outside the front door. He appeared on the far side of the lawn and marched purposefully, and with dignity – or as much as is possible for a fat warty creature – towards the door, and into the house. I had to remove him to the far end of the garden, but a couple of evenings later he returned, and again went into the house.
Haven't seen him for a while, and there have been very few other toads recently, or frogs, even though I built a pond. Three frogs appeared for a while, but there were no tadpoles. It seems the amphibians are much reduced, by virtue of habitat, climate and weather changes, and I believe some virus.
