Serranus Basses belong all to the same genus „Serranus spp.“ and the family „Serranidae“ (groupers and sea basses) subfamily „Serraninae“. The Serranidae Family is very large in size and includes Bacalasos, Basslets, Cabrillas, Camolillos, Coneys, Grasbys, Groupers, Hamlets, Hinds, Leather Basses, Reef Basses, Sand Perches, Sea Basses, Serranos, Soapfishes, Splittail Bases and finnaly Threadfin Basses. There are approximately 450 global members of this family from 68 genera, the genus Serranus spp. Is one of the smaller one. Due to the considerable diversity and habits amongst the individual members it is difficult to provide detailed family characteristics.
However, they all have compressed robust bodies, one dorsal fin, large mouths with more than one row of teeth with the rear bone of the upper jaw being fully exposed on the cheek when the mouth is closed, and a lateral line that extends into the tail base. The gill covers are characteristic being serrated and have three spines. Their bodies are covered with small rough scales. Most of the members of this family are bottom dwellers and found in and around rocky reef structures; they are voracious predators feeding on fishes and crustaceans.
