Barbo comizo - Iberian barbel - Barbus comizo
- Endemic to the Tagus and Guadiana river basins in Spain and Portugal.
- It is estimated that B. comizo has undergone a population decline of at least 30% in the past 10 years due to water extraction, pollution and introduced taxa (Crivelli, A. pers comm.) this has led to a continuous decline in numbers and in area of occupancy.
- It prefers the middle and lower reaches of rivers, in deep and slow waters with abundant submerged vegetation. It occurs also in reservoirs. It is a large size barbel (>500mm )

Jarabugo - Spanish minnow - Anaecypris hispanica

- An endemic fish to the Iberian Peninsula. Most of the distribution is within Spain and some in Portugal (Guadiana river basin) (extent of occurrence <5,000 km²
- A. hispanica has experienced a decline in population of >50% in 10 years, and it is ongoing in spite of the establishment of a conservation program. The population is fragmented due to dams and is declining due to water extraction, introduced species and pollution.
- This species lives most of the time in small intermittent streams of the Guadiana River basin with high dissolved oxygen concentrations, coarse substratum, shallow depth and water temperature below 25°C. It is a short-lived species (maximum three years old) achieving a small size (< 60 mm). Reproduction takes place in April¿May. It is a species with limited dispersal. (Doadrio 2001).

- Threatened by Drought, habitat destruction, water extraction, domestic and agricultural pollution and introduction of Gambusia holbrooki
