Scorpina - another tasty fish

The Scorpaenidae (also known as scorpionfish) are a family of mostly marine fish that includes many of the world's most venomous species. As their name suggests, scorpionfish have a type of "sting" in the form of sharp spines coated with venomous mucus. The family is a large one, with hundreds of members.[2] These belong to the higher taxon of Actinopterygii (ray-finned fish).[3] They are widespread in tropical and temperate seas, but mostly found in the Indo-Pacific. They should not be confused with the cabezones, of the genus Scorpaenichthys, which belong to a separate, though related, family, Cottidae.

Some types, such as the lionfish, are attractive as well as dangerous, and highly desired for aquaria. In addition to the name scorpionfish, informal names for family members include firefish, turkeyfish, dragonfish, and stingfish, usually with adjectives added.

General characteristics of family members include a compressed body, ridges and/or spines on the head, one or two spines on the operculum, and three to five spines on the preopercle. The dorsal fin has 11 to 17 spines, often long and separated from each other, and the pectoral fins are well-developed, with 11 to 25 rays. The spines of the dorsal, a**l, and pelvic fins all have venom glands at their bases.[4]

Most species are bottom-dwellers that feed on crustaceans and smaller fish. Many inhabit shallow waters, but a few live as deep as 2,200 m (7,200 ft).[2] Most scorpionfish, such as the stonefish, wait in disguise for prey to pass them by before attacking, while lionfish often ambush their prey. When not ambushing, lionfish may herd the fish, shrimp, or crab into a corner before swallowing. Like many perciform fishes, scorpionfish are suction feeders that capture prey by rapidly projecting a suction field generated by expansion of the fish's buccal cavity.

The Scorpaenidae, which became popular because of the specimens found within it, is composed of smaller families. These are the Scorpaeninae (scorpionfishes), Sebastinae (rockfishes), and Pteroinae (lionsfishes or turkeyfishes); this last one being the one in which the previously mentioned lionfish belongs to.[5]

Scorpaenid systematics are complicated and unsettled. Fishes of the World recognizes 10 subfamilies with a total of 388 species, while (as of 2018) FishBase follows Eschmeyer and has three subfamilies, 25 genera, and 222 species.

If you have chance, dont miss to try this fish:

John Dory, St Pierre or Peter's Fish, refers to fish of the genus Zeus, especially Zeus faber, of widespread distribution. It is an edible demersal coastal marine fish with a laterally compressed olive-yellow body which has a large dark spot, and long spines on the dorsal fin. The dark spot is used to flash an 'evil eye' if danger approaches. Its large eyes at the front of the head provide it with binocular vision and depth perception, which are important for predators. The John Dory's eye spot on the side of its body also confuses prey, which are scooped up in its big mouth

Various, often doubtful explanations are given of the origin of the name. It may be an arbitrary or jocular variation of dory (from French dorée, gilded), or an allusion to John Dory, the hero of an old ballad. Others suggest that "John" derives from the French jaune, yellow. The novel An Antarctic Mystery by Jules Verne gives another account, which has some popularity but is probably fanciful: "The legendary etymology of this piscatorial designation is Janitore, the 'door-keeper,' in allusion to St. Peter, who brought a fish said to be of that species, to Jesus at his command." Other known names for the John Dory are the "St. Pierre", or "Peter's Fish", perhaps explaining why dories were often referred to as "Peter Boats", Saint Peter being the patron saint of fishermen.[5] A related legend says that the dark spot on the fish's flank is St. Peter's thumbprint.[6] In the north coast of Spain, it is known commonly as San Martiño.
