Caproidae
Caproidae, or boarfishes, are a small family of marine fishes comprising two genera and 12 species. They were formerly placed in the order Zeiformes with the dories, but are now placed with the Perciformes since they have many perciform characteristics, for instance in the caudal skeleton. Boarfishes are native to the Indian, Atlantic, and Pacific Oceans, where they are mainly found at depths below . Boarfishes have deep and thin bodies. They are small, with only a few species known to reach a maximum total length of . Their coloration is red, pink, and silvery. The earliest identified caproid fossils date to the middle Eocene epoch of the early Tertiary Tertiary ( ) is a widely used but obsolete term for the geologic period from 66 million to 2.6 million years ago.

Capros (genus)
The boarfish (''Capros aper'') is a species of fish in the family Caproidae, the only known member of its genus. Its scientific name is from Greek κᾰ́προς (''kapros'') and Latin ''aper'', both meaning "wild boar." Description ''Capros aper'' commonly reaches a length of about 13 cm in males, with a maximum length of about 30 cm. The weight reaches about 85 g. The female is larger than male. This fish has large eyes, a quite long snout, and a very protractile mouth that forms a short tube when extended. The general form of the body can be defined as rhombic, quite deep, and compressed. The dorsal fin is unique, the caudal fin is rather large and spatulated with a convex edge, the ventral fins are very large and have a thorny spine, and the pectoral fins are quite small. The color of the body is reddish orange, sometimes with three wide darker bands, one behind the eye, one in the center of the body, and one on the caudal peduncle. During the breeding se ...

Zeiformes
The Zeiformes are a small order of marine ray-finned fishes most notable for the dories, a group of common food fish. The order consists of about 33 species in seven families, mostly deep-sea types. Zeiform bodies are usually thin and deep. Mouths are large, with distensible jaws, and there is no orbitosphenoid. Pelvic fins have 5–10 soft rays and possibly a spine, 5–10 dorsal fin spines and up to 4 anal fin spines. They range in size from the dwarf dory ''(Macrurocyttus acanthopodus)'', at in length, to the Cape dory ''(Zeus capensis)'', which measures up to . The boarfishes (Caproidae) have been included in this order though they are currently included in the Perciformes.

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Pentacerotidae
Pentacerotidae or armourheads are a small family of fishes in the order Perciformes. They are native to the Indian Ocean, western and central Pacific, and southwestern Atlantic. They are generally found at rocky reefs below normal scuba diving depths, although several species occur in low densities at shallower depths. Their name, from Greek ''pente'' meaning "five" and ''keras'' meaning "horn", refers to the prominent, sharp spines in their dorsal fins (though these do not number five in all species). The largest species in the family (''Paristiopterus'') may reach a length of . Many species have distinct dark-and-light-striped bodies, while others are overall dusky-silvery.

Tertiary
Tertiary ( ) is a widely used but obsolete term for the geologic period from 66 million to 2.6 million years ago. The period began with the demise of the non-avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene Epoch. The time span covered by the Tertiary has no exact equivalent in the current geologic time system, but it is essentially the merged Paleogene and Neogene periods, which are informally called the Early Tertiary and the Late Tertiary, respectively. The Tertiary established the Antarctic as an icy island continent. Historical use of the term The term Tertiary was first used by Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, the Quaternary, was applied.

Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Perciformes
Perciformes (), also called the Percomorpha or Acanthopteri, is an order or superorder of ray-finned fish. If considered a single order, they are the most numerous order of vertebrates, containing about 41% of all bony fish. Perciformes means "perch-like". Perciformes is an Order within the Clade Percomorpha consisting of "perch-like" Percomorphans. This group comprises over 10,000 species found in almost all aquatic ecosystems. The order contains about 160 families, which is the most of any order within the vertebrates. It is also the most variably sized order of vertebrates, ranging from the ''Schindleria brevipinguis'' to the marlin in the genus ''Makaira''. They first appeared and diversified in the Late Cretaceous. Among the well-known members of this group are perch and darters (Percidae), sea bass and groupers (Serranidae). Characteristics The dorsal and anal fins are divided into anterior spiny and posterior soft-rayed portions, which may be partially or compl ...
