Ladder Snake

Rhinechis scalaris

Cobra de escada

IUCN Red List Status:

Least Concern; Population Trend Stable; Last Assessed Dec 2008

Juvenile Ladder Snakes have a totally different look to adults. They have characteristic "H" shaped marks along the back, which look somewhat ladder-like, hence the name "ladder snake".

This species is non-venomous.

 

 

Adult Ladder Snakes do not have the ladder markings on the back. Instead they have a black line running down the top of the body, one on each side.

 

Iberian False Smooth Snake

Macroprotodon brevis

Cobra de capuz
Near Threatened; Population Trend Decreasing; Last Assessed Dec 2008

  Newts & Salamanders

 

 

Sharp-ribbed newt

Pleurodeles waltl

Salamandra de costelas salientes

IUCN Red List Status:

Near Threatened; Population Trend Decreasing; Last Assessed Dec 2008

Sharp-ribbed Newt. This species has an amazing defence mechanism. Along each flank is a row of orange spots. When picked up and threatened they poke their ribs through the spots, where they pick up some venom, so the sharp rib points inject poison into their potential attacked promting it to let the newt go.

Sharp-ribbed Newt just prior to being released into our pond.

Sharp-ribbed Newts can grow up to 30cm in length.

 

 

Two Sharp-ribbed newts being relocated to my pond having been discovered in my borehole cistern during cleaning operations.

Two Sharp-ribbed Newts discovered on the reserve. This species is listed as ‘Near Threatened’ on the IUCN Red List of Threatened Species. Very exciting news indeed. Very exciting to have the opportunity to provide a safe home for a near threatened amphibian. Hopefully they will stay in our pond and thrive.
