REPTILES residing on Exmoor presently make up 2 snake and 2 lizard types – one is the slow-worm. You might be forgiven for believing that the slow-worm is a snake too, however in truth it’s technically a lizard!
Reptiles are cold-blooded and require an external source of heat to manage their body temperature level. They help this procedure by indulging in the sun throughout the warmer months, and hibernating over the cooler durations, typically in groups of people of the exact same types.
We have actually seen a juvenile yard snake huddled with slow-worms throughout the summer season, so maybe this can take place throughout hibernation too.
Reptiles are covered in scales or bony plates that are shed regularly to enable development, so juveniles shed more regularly than grownups. Lizards shed their scales in little pieces however snakes in one piece. Reptiles which have actually just recently shed their skin typically have a rainbowlike shine.
The 2 lizard types discovered on Exmoor are the slow-worm (Anguis fragilis) and the typical lizard (Zootoca vivipara).
Slow-worms appear like snakes and are typically incorrect for them, however they are in fact legless lizards with glossy pale brown or golden scales. Older males sometimes sport blue areas however they do not have the dark brown sides that women reveal, in addition to a stripe along their backs.

With a length of in between 40-70 cm and a weight of 20-100 grams, sluggish worms are not huge, yet they have an astonishingly long life-span of 20 to thirty years – one was even reported to live for 52 years in captivity (however that was several years back, so was never ever validated).
In reality, numerous never ever reach their complete life-span. Slow-worms are on the menu for numerous mammals, birds and adders, and numbers likewise get killed on our roadways.
However, slow-worms do have a technique or more up their sleeves to secure themselves from being captured and consumed. I can personally affirm that they are far from sluggish when it concerns leaving predators, having actually seen one leaving at speed from a dick pheasant.
Should slow-worms feel threatened, their very first line of defence is to freeze, then to run away. If captured they defecate, and if that doesn’t hinder the attacker, they can remove their tail which will twitch quickly in the hope that the predator will be sidetracked enough time to let the slow-worm escape.
This procedure is called autotomy and is utilized by numerous lizard types. The tail stump rapidly heals and ultimately begins to re-grow.
Slow-worms hibernate buried in the soil from November to early March. After emerging and heating up adequately, they go about looking for victim: typically slugs. These, besides being terribly slimy, can be challenging to swallow so the slow-worm help intake by burrowing into the soil, assisted by its glossy scales.
Friction from the soil eliminates the slime from its victim. What a smart and beneficial animal to invite into your gardens, where they are typically discovered, a garden enthusiasts’ friend certainly!
Love-making slow-worm design is a prolonged and rather ruthless affair with the male biting the female’s head or neck and holding her whilst they lace and copulate for as much as 10 hours.
Up to 12 small young, about 4 cms long, are born in August or September. By October hibernation starts once again.
Placing a corrugated iron or other metal sheet in a warm place in your garden will draw in slow-worms and permit them to heat up faster.

Common lizards are the types you are more than likely to find on Exmoor. They regularly indulge in bright areas on logs, stony ground, tree trunks with gnarly bark or clumps of flattened plant life in the spring and fall, flattening themselves to increase the area exposed to the sun.
They will scuttle away into denser plant life with a rustling sound if disrupted.
Common lizards reach a size of 10-15cms – half of which is comprised of their tails. The tail, similar to slow-worms, can be shed to get away predation from the numerous birds, mammals and adders that feed upon them.
Colours differ from black to vibrant green although the majority of are differing tones of brown, striped and speckled for camouflage. Males have actually brilliantly coloured underbellies: yellow or orange with dark areas.
Female underbellies are pale and plain. Emerging from hibernation is typically a common affair in March or April. Common lizards look for their invertebrate victim utilizing sight, aroma and noise. They bite along the length of the unlucky victim prior to swallowing it entire, typically head initially, in typical with the majority of reptiles.
Females mate a number of times with several males in April or May. The birth of 3 to eleven young is normally 3 months later on, in July. Sunshine assists the young to hatch. Sometimes they even hatch inside the mom and twitch out. Lizards need to live for 5 to 6 years, supplied they can get away being consumed.
All our British reptiles are unfortunately under risk, with damage of their environment for advancement, extensive farming and hectic roadways, on which numerous get run over.
