Appearance
Serranids are generally robust in form, with large mouths and small spines on the gill coverings. They typically have several rows of sharp teeth, usually with a pair of particularly large, canine-like fangs projecting from the lower jaw. Many serranid species are brightly colored.
They generally have ten spines in their dorsal fins and seven soft rays in their anal fins. They are also characterised by the fin spines being unserrated. The genera within the Serranidae are separated by the meristics of the soft rays in the dorsal fin.
All serranids are carnivorous, feeding on other fish and crustaceans. They are typically ambush predators, hiding in cover on the reef and darting out to grab passing prey. Their bright colours are most likely a form of disruptive camouflage, similar to the stripes of a tiger.
