Fits into Mediterranean zoogeographic area. Animals that live in the Park are very interesting and geologicaly speaking, very old. In the periods of Ice ages, It has not been covered with ice so very distinctive animal life had a chance to thrive here.
Besides the very rich ornithofauna (bird species) that is described in the section ABOUT RESERVE, other animal species are also interesting and diverse.
Water in the lake is a bit salty, and considering that sea water penetrates the lake basin, freshwater, as well as marine fish species are present in the lake. Of all the freshwater fish in the lake, only Eel (Anguilla anguilla) and River Blenny (Salaria fluviatilis) are autochthonous which means that it is is their natural habitat. Other species were introduced into the lake, either on purpose or accidentally.

Mullets are the most common marine fish in the lake.

Most of the amphibians are under law protection. Most common are Marsh Frog (Rana ridibunda), Common Tree Frog (Hyla arborea), Agile Frog (Rana dalmatina) and different toads (Bufo sp.). Sometimes you can find salamanders (Salamandra salamandra), newts (Triturus vulgaris) and Yellow-Bellied Toad (Bombina variegata).
