This database is available at: http://www.fauna-iberica.mncn.csic.es/english/proyecto/index.php The objective of the Iberian Fauna Project is to carry out all types of scientific studies that will allow the acquisition of basic zoological information about animal biodiversity in the Iberian-balearic region. These studies are mainly oriented to increasing the systematic study of animals by analyzing the distribution of the species in order to estimate the areas that need greater protection. With the Iberian Fauna web project the National Museum of Natural Sciences is seeking to develop an information center of the zoological biodiversity in our country that will facilitate taxonomical work , and will help disseminate the current knowledge of the Iberian animal world to the general public at large. Covered Phyla include: Porifera (esponjas), Entoprocta, Cnidaria (medusas, corales, anémonas), Cycliophora, Ctenophora, Mollusca (caracoles, almejas, pulpos, etc.), Placozoa, Pogonophora, Myxosporidia, Echiura, Platyhelminthes (planarias, fasciolas, tenias), Sipuncula (sipuncúlidos), Gastrotricha, Annelida (lombrices de tierra, gusanas, sanguijuelas), Gnathostomulida, Arthropoda (insectos, cangrejos, arañas, garrapatas, ciempiés, etc.), Nemertea, Tardigrada, Mesozoa, Bryozoa, Rotifera (rotíferos), Brachiopoda, Nematoda, Phoronida, Nematomorpha, Chaetognatha, Kinorhyncha, Echinodermata (erizos de mar, estrellas de mar), Acanthocephala, Hemichordata, Priapula, Urochorda (ascidias, salpas, larváceos), Chordata (anfioxos, lampreas, peces, anfibios, reptiles, aves, mamíferos).
