Hemiramphidae is a family of fishes that are commonly called halfbeaks, spipe fish or spipefish. They are a geographically widespread and numerically abundant family of epipelagic fish inhabiting warm waters around the world. The halfbeaks are named for their distinctive jaws, in which the lower jaws are significantly longer than the upper jaws. The similar viviparous halfbeaks have often been included in this family.
Bovichtidae, the temperate icefishes or thornfishes, is a family of marine ray-finned fishes, classified in the suborder Notothenioidei of the order Perciformes. They are native to coastal waters off Australia, New Zealand, and South America.
The Percophidae, duckbills, are a family of percomorph fishes, from the order Trachiniformes, found in tropical and subtropical waters of the Atlantic and Indian Oceans and in the southwestern and southeastern Pacific.
The marbled rockcod is a species of marine ray-finned fish, belonging to the family Nototheniidae, the notothens or cod icefishes. It is native to the Southern Ocean, where it can be found at depths from 5 to 350 m. This is a commercially important species.
The largetooth cookiecutter shark is a rare species of squaliform shark in the family Dalatiidae, reported from depths of 60–200 m (200–660 ft) at scattered locations in the Atlantic and Pacific Oceans. As its common name suggests, it is similar in appearance to the cookiecutter shark but has much larger lower teeth. This species reaches a maximum known length of 42 cm (17 in). The largetooth cookiecutter shark feeds by gouging out chunks of flesh from larger animals, including bony fishes, sharks, and marine mammals, and is able to take larger bites than I. brasiliensis. Little is known of its life history; it is thought to be a weaker swimmer than I. brasiliensis, and is presumably aplacental viviparous like the rest of its family. This shark is an infrequent bycatch of commercial trawl and longline fisheries, but is not thought to be much threatened by these activities.
Sardinella is a genus of fish in the family Dorosomatidae found in the Atlantic, Indian and Pacific Ocean. They are abundant in warmer waters of the tropical and subtropical oceans. Adults are generally coastal, schooling, marine fish but juveniles are often found in lagoons and estuaries. These species are distinguished by their ranges and by specific body features, but they are often confused with one another. Fish of the genus have seven to 14 striped markings along the scales of the top of the head. The paddle-shaped supramaxilla bones are characteristic; they separate Sardinella from other genera and their shapes help distinguish species. They have paired predorsal scales and enlarged fin rays.
Trachiniformes is an order of percomorph bony fish, whose contents are traditionally placed in suborder Trachinoidei of Perciformes.
Notothenia is a genus of marine ray-finned fishes belonging to the family Nototheniidae, the notothens or cod icefishes with the species in this genus often having the common name of rockcod. They are native to the Southern Ocean and other waters around Antarctica.
The Sierra Spanish mackerel is a species of fish in the family Scombridae. Specimens have been recorded at up to 125 cm in length, and weighing up to 6.71 kg. It is found in the western Atlantic, along the Caribbean and Atlantic coasts of Central and South America from Belize to Rio Grande do Sul, Brazil. Literature records for S. maculatus from the area apply to S. brasiliensis, which has erroneously been considered a synonym of S. maculatus by many authors. It feeds on small fish, squid/cuttlefish, shrimp/prawn, and isopods.
