There are 13 types of snake indigenous to the Iberian peninsula,
however if you avoid their natural habitats when you are
in Portugal you are unlikely to encounter them. Snakes
tend to like damp, cool places during the summer months
where they can keep out of the heat of the sun. However
first thing on a morning you can glimpse some warming
their bodies on the warmth of the roads. |
Montpellier Snake
(Malpolon monspessulanus)
|
|
Venomous, but not usually enough to kill a human but bad enough to inflict a good deal of pain. It usually inhabits dry, stony areas heavily populated by lizards such as piles of stones on the edges of fields or near ruined buildings. when hunting it will occasionally rear up and look around, making it resemble the cobra. If it feels threatened it hisses loudly and attacks with the mouth closed. One
of its distinguishing features is in fact the prominent ridge above its eyes. It can grow quite large (up to two metres) and is blue with a white underbelly. |
Ladder Snake
(Elaphe scalaris)
|
Derives its scientific and common name from the markings of its young, which in addition to the pair of dorsal stripes running down the back have dark bars running across their backs. It inhabits coastal regions and can usually be found in sunny areas, stony slopes, open deciduous woods, vineyards. Grows to 1.60m. Juveniles have distinctive ladder pattern, of which the "rungs" fade to
become lateral lines when adult. A constrictor. No fangs. |
