The aquatic vegetation of the Somolinos lagoon is made up of compact formations of Magnocharetum hispidae"), which form mats on the bottom and on the walls of the basin, and Greenland dense.

As unique species in the aquatic flora, Sparganium emersum and Zannichellia contorta") stand out. Other species of aquatic flora found in the lagoon are Chara vulgaris"), Lemna minor and Ranunculus peltatus.

The marginal vegetation is integrated, on the edge of the lagoon, by reeds and sedges, typical of waterlogged soils that can suffer a certain desiccation at the end of summer, and by *Cladium mariscus"). Towards the exterior of the lagoon these formations are replaced by clumps of reeds.

Towards the less flooded areas, meadows dominated by lagoon reeds are recognized, which come into contact with Juncus inflexus" meadows. In the northern area of ​​the lagoon, where the Manadero River flows, small extensions of basophilic meadows appear. On the banks of the streams that reach the lagoon, willows appear surrounded by brambles. In some areas this marginal vegetation has been replaced by poplar plantations.

The birdlife of the Somolinos lagoon is quite simple, basically made up of the little grebe, the moorhen, the mallard, the coot, the gray heron and the lapwing.

Among the non-aquatic birds, the birds of prey stand out with a nesting colony of griffon vultures. Other endangered birds that breed in the surrounding area use the area as a regular hunting ground, generally the golden eagle, the short-toed eagle, the hawk, the Egyptian vulture, the red kite, the peregrine falcon and the eagle owl. Other species of interest are the red-billed chough, the sandgrouse, the common dove, the gray nightjar, the red rock thrush, the Montagu's harrier, the Dupont's lark and the white-capped blackbird. The presence of the red-backed shrike during the breeding season has also been recorded. Other birds present are the red partridge and other passing game birds.

In the amphibian community, the presence of the common salamander, the marbled newt, the common midwife toad and the San Antonio frog stand out. As for reptiles, the presence of the European pond turtle, the kittiwake skink, the blind snake, the European smooth snake, the long-nosed viper, the black-green lizard and the lution stand out.

Regarding the mammal community, the otter, the badger, the wild cat, the marten, the weasel, the Iberian mole, the water rat, the rabbit, the hare, the fox, the roe deer and the wild boar stand out, as well as the community of bats that uses this territory as a feeding area.

Among the ichthyofauna, the populations of vermilion and native trout stand out.

The Cocinilla slope, next to the lagoon, is proposed as "Global Geosite" (Spanish geological site of international relevance) by the Geological and Mining Institute of Spain due to its stratigraphic interest, with the name "MZ006: Laguna de Somolinos" within the group of geological contexts "The rifting of Pangea and the Mesozoic successions of the Betic and Iberian mountain ranges."[1]​.
