In Greek, debates means “magnificent”, and paucispinis is Latin for “having few spines”. Boccaccio can be found from Slovak Bay, Alaska to central Baja California, but is mostly abundant from Oregon to northern Baja California.

Juveniles stay in shallower water because of the protection provided by floating kelp mats or driftwood. Shallow water kelp forests and oil platforms also help these fish avoid danger, as they can use them to dodge and hide from predators.

As the fish get older, they to move into deeper, colder water. The Monterey submarine canyon is an ideal place for many marine organisms to inhabit or migrate through, and Boccaccio in this canyon can consume multiple marine species such as shellfish (pelagic shrimp and crab), anchovies, sardines, other small rock fishes, and squid.

The Boccaccio is one of the larger rock fish and can grow up to 3 feet (0.91 m) in length and live to 45 years. Females grow faster than males and also live longer.

Certain effects of strong and weak upwelling affect the Boccaccio's food sources and the survival of its larvae. When the water is cold the upwelling is strong with more productivity and warmer water produces a weaker upwelling with a low amount of resources.

El Niño and La Niña effect of the upwelling due to the drastic changes in the warmth of water. Recreational and commercial fisheries off the coast of California rely heavily on Boccaccio.

Commercial fishermen tend to target Boccaccio due to their abundance and longer shelf life. The California Department of Fish and Game has set a regulation limit of 2 bocaccios per day at a minimum length of 10 inches (250 mm).

Also, the depths of fishing have decreased now as older and larger Boccaccio tend to stay deeper because the deepest fishermen can fish at is around 240 feet (73 m). Studies off of Southern California oil platforms show they have produced a slight increase on Boccaccio population.

Juveniles like to use these platforms as they provide a resemblance of a natural habitat with more protection, and because of the availability of plankton. In January 2001 the U.S. National Marine Fisheries Service (NFS) received a petition to list the southern population of Boccaccio as a Threatened species under the U.S.

In November 2002, NFS published its recommendation that ESA listing was not warranted. The southern distinct population segment of Boccaccio is a U.S. National Marine Fisheries Service Species of Concern.

Species of Concern are those species about which the U.S. Government's National Oceanic and Atmospheric Administration, National Marine Fisheries Service has some concerns regarding status and threats, but for which insufficient information is available to indicate a need to list the species under the U.S. On October 29, 2007, NFS received a petition from Mr. Wright to list the Puget Sound DPS of Boccaccio under the ESA.

NFS listed the Puget Sound/Georgia basin Distinct population segment as endangered on April 28, 2010. IUCN Red List of Threatened Species.

The common name grouper is usually given to fish in one of two large genera : Epimetheus and Mycteroperca. In addition, the species classified in the small genera Hyperion, Completes, Dermatologist, Graciela, Scotia, and Trio are also called 'groupers'.

However, some hamlets (genus Affected), the hinds (genus Cephalopods), the lyre tails (genus Various) and some other small genera (Gonioplectrus, Nippon, Paranoia) are also in this subfamily, and occasional species in other serrated genera have common names involving the word grouper “. Nonetheless, the word grouper on its own is usually taken as meaning the subfamily Epinephrine.

Groupers are Telecasts, typically having a stout body and a large mouth. They can be quite large, and lengths over a meter and the largest is the Atlantic Goliath grouper (Epimetheus Tamara) which has been weighed at 399 kilograms (880 pounds) and a length of 2.43 m (7 ft 11 1 2 in), though in such a large group, species vary considerably.

They do not have many teeth on the edges of their jaws, but they have heavy crushing tooth plates inside the pharynx. They habitually eat fish, octopuses, and crustaceans.

Reports of fatal attacks on humans by the largest species, such as the giant grouper (Epimetheus lanceolatus) are unconfirmed. They also use their mouths to dig into sand to form their shelters under big rocks, jetting it out through their gills.

The word grouper is from the Portuguese name, group, which has been speculated to come from an indigenous South American language. In New Zealand, “groper” refers to a type of wreck fish, Poly prion oxygenate, which goes by the Mori name haiku.

In the Middle East, the fish is known as hammer ', and is widely eaten, especially in the Persian Gulf region. The species in the tribes Grammistini and Diploprionini secrete a mucus like toxin in their skin called Rammstein and when they are confined in a restricted space and subjected to stress the mucus produces a foam which is toxic to nearby fish, these fishes are often called soap fishes.

Groupers are mostly monastic protogynous hermaphrodites, i.e. they mature only as females and have the ability to change sex after sexual maturity. The largest males often control harems containing three to 15 females.

As such, if a small female grouper were to change sex before it could control a harem as a male, its fitness would decrease. If no male is available, the largest female that can increase fitness by changing sex will do so.

Gonochorism, or a reproductive strategy with two distinct sexes, has evolved independently in groupers at least five times. The evolution of gonochorism is linked to group spawning high amounts of habitat cover.

Both group spawning and habitat cover increase the likelihood of a smaller male to reproduce in the presence of large males. Fitness of male groupers in environments where competitive exclusion of smaller males is not possible is correlated with sperm production and thus testicle size.

Gonochoristic groupers have larger testes than protogynous groupers (10% of body mass compared to 1% of body mass), indicating the evolution of gonochorism increased male grouper fitness in environments where large males were unable to competitively exclude small males from reproducing. Many groupers are important food fish, and some of them are now farmed.

Unlike most other fish species which are chilled or frozen, groupers are usually sold live in markets. Groupers are commonly reported as a source of Ciguatera fish poisoning.

DNA barcoding of grouper species might help in controlling Ciguatera fish poisoning since fish are easily identified, even from meal remnants, with molecular tools. In September 2010, a Costa Rican newspaper reported a 2.3 m (7 ft 7 in) grouper in Cieneguita, Limón.

The weight of the fish was 250 kg (550 lb) and it was lured using one kilogram of bait. In November 2013, a 310 kg (680 lb) grouper had been caught and sold to a hotel in Dong yuan, China.
