Resumen: "A systematic checklist is presented for the marine estuarine fishes of Chiapas, Mexico, including notes on their zoogeography and conservation status. The checklist includes 379 species, two classes, 30 orders, 91 families, and 207 genera. Actinopterygii is themost diverse class (323 species, 181 genera, 72 families, and 23 orders), while Chondrichthyes (56 species, 26 genera, 19 families, and seven orders) is the least diverse class. Perciformes is the richest order (175 species, 98 genera, and 32 families), including seven families representing 32.2% of the total fish diversity reported here: Sciaenidae (25 species), Carangidae (21), Gobiidae (20), Haemulidae (14), Epinephelidae (11), Dactyloscopidae (10), and Gerreidae (10). Based on a taxonomical review of specimens in fish collections and literature-verified records, the list is composed of marinestenohaline (46.7%), marine-euryhaline (48.8%), primary freshwater (1%), secondary freshwater (2.6%), and diadromous (0.2%) species. The ichthyofauna showed greater zoogeographic affinity to theMexican (81.5%) and Panamic (80.5%) provinces, while 48 species are circumtropical, four amphipacific, five amphiamerican, and one exotic (Oreochromis niloticus). Based on the IUCN Red List, 259 species are of BLeast Concern^, 18 are BNear Threatened^, 11 are BVulnerable^, two are BCritically Endangered^ (Pristis pectinata and P. pristis), and one is BEndangered^ (Rhincodon typus)"
