An invasive species, the red-eared terrapin (Trachemys scripta elegans), also known as the red-eared slider, red-eared slider turtle, red-eared turtle, slider turtle, and water slider turtle, is a semiaquatic terrapin belonging to the family Emydidae.
Continue reading Invasive species – The red eared terrapinThe shell of the Mediterranean pond terrapin is olive, brown or grey. The limbs are short and stout, with orange or yellow lines that fade in the older specimens. The carapace normally measures between 13 to 17cm (5 – 6¾ inches) but can occasionally reach 20 cm (8 inches) and is slightly convex in shape. The base of the shell is yellowish, with large blackish spots which fade with age.
It is relatively abundant in the rivers, reservoirs, ponds and all types of aquatic bodies in Spain with good vegetation and refuge on the banks. Sometimes they can be seen in dirty and contaminated water as is often the case when towns and villages in Spain have inadequate sewage treatment works.
They spend many hours sunbathing at the water’s edge or on semi-submerged logs and rocks, quickly diving and staying underwater for long periods at the slightest sign of danger.
The Mediterranean Pond Terrapin is a skilful hunter of fish, amphibians and their larvae, aquatic insects and also feed on carrion.
I have even observed them feeding on livestock excrement (goat and cow)
The breeding season begins in March continuing to July. Up to 22 eggs are laid days 15 to 68 days after copulation which are normally divided between 2 clutches with a 21 to 32 day interval. Hatching occurs after 56 to 82 days.
The name ‘leprosa‘, refers to the algae which grows on its shell which can cause a perforation and deformation of the plates and sometimes gives a malformed appearance. (If you have ever handled a Mediterranean Pond Terrapin then you have also probably noticed the awful stench coming from its shell!)
