There are three pattern variations in this species: almost uniformly colored animals; animals with large dark spots with bright edges and animals with two dark brown longitudinal bands, one bright band along the back and two bright bands along the sides. The belly is whitish.

The body is stout with a flat head that is wider than it is long. The dorsal glands are arranged in longitudinal patterns along the back, or can be absent. The pupil is shaped like an upside-down droplet (Noellert and Noellert 1992).

D. galganoi is similar in appearance to D. jeanneae, but can be distinguished from the latter by biochemical and morphometric characteristics (Busack 1986). The distinction between D. jeanneae and D. galganoi is also supported by phylogenetic work based upon mitochondrial sequences (Garcia-Paris and Jockusch 1999).

D. galganoi is endemic to the Iberian Peninsula. It inhabits Portugal and the western part of Spain. Previous studies separated vD. galganoi from D. jeanneae, which inhabits the eastern part of Spain by the Guadalquivir river in the southern part of its distribution, and by the saline lakes in the central part of the Iberian Peninsula, with contact zones between the two species in the eastern portion of the Sierra Morena, near the Sierra de Guadarrama and along the northwestern edge of the Meseta Norte (Garcia-Paris and Jockusch 1999). However more recent studies consider D. jeanneae a subspecies or too closely related lineage to differentiate genetically. See Speybroeck et al 2020 for a summary.

This frog is mostly found in or in the direct vicinity of water. They are found in stagnant waters, in swamps and mountain streams and even in brackish waters (Noellert and Noellert 1992).

Life History, Abundance, Activity, and Special Behaviors
The reproductive period of D. galganoi starts in October, and ends in late summer. During this period, the female can produce up to six clutches, each of 300 to 1500 eggs. Over the entire breeding season, she can produce as many as 4900-5600 eggs. Each female mates with a number of males, and each mating she produces 20 to 50 eggs. These eggs are laid singularly or as small clumps on the bottom, or are attached to plants. Eggs have a diameter of 1.5-2 mm, the gelatinous envelope measuring 6-8 mm. Depending on water temperature, the embryonic development takes 2 to 6 days. Larvae are 3mm in length upon hatching, and grow to a total length of 25 to 35 mm. The diurnal larvae are mostly found in December, March and May. Larval development takes 22 to 60 days, and newly metamorphosed frogs have a snout-vent length of about 10 mm. Sexual maturity is reached at an age of 3-5 years for males, and at an age of about 4 years for females. Total life span is estimated at about 9 years.

D. galganoi is active when water temperatures rise above 9°C. The optimum temperatures for this species is between 21 and 30°C. The animals become inactive when the relative humidity of the air drops below 45% (Noellert and Noellert 1992).

Trends and Threats
This species seems to be abundant throughout its entire range. As an ubiquitous frog species it is not endangered by specific threats; however, marginal and sparse populations, which possibly represent distinct genetic lineages, are threatened and in some cases became extinct because of the destruction of their habitats (Gasc 1997).

Possible reasons for amphibian decline

General habitat alteration and loss

Speybroeck et al (2020) summarizes molecular studies on Discoglossus and notes that the broad hybrid zone between galganoi and jeanneae, lack of monophyly based on nuclear data, evidence of introgression, and generally lack of barriers to gene flow support treating these as the same species.
