Kentrocapros spilonotus is a species of marine ray-finned fish belonging to the family Aracanidae, the temperate boxfishes or deepwater boxfishes. This species is known from two places in the Hawaiian Islands, one near Laysan and the other is the Penguin Bank.
Kentrocapros spilonotus was first formally described as Aracana spolinota in 1905 by the American ichthyologist Charles Henry Gilbert with its type locality given as Albatross station 3939 near Laysan Island in the Leeward Islands of Hawaii from a depth between 59 and 163 fathoms (354 and 978 ft; 108 and 298 m). [3] In 2006 Keiichi Matsuura examined the known Specimens of A. spilonota and reclassified it into the genus Kentrocapros . [4] The 5th edition of Fishes of the World classifies the genus Kentrocapros in the family Aracanidae which is in the suborder Ostracioidea within the order Tetraodontiformes. [5]
Kentrocapros spilonotus is classified within the genus Kentrocapros, a name which combines kentro meaning "thorn" or "spine", a reference to the spiny ridge along the flanks of the type species, K. aculeatus , with capros, meaning "wild boar". This may allude to these fishes being known as seapigs in the 19th Century, probably an allusion to the resemblance of these fishes on a rear view to a pig. The specific name, spilonotus, means "spot-backed" and refers to the brownish-green spotting on the back and upper bodty ofthis fish. [6]
Kentrocapros spilonotus has between 9 and 11 soft rays in its dorsal fin and between 9 and 12 on the anal fin. There is a stiffcarapace which covers all of the body except the caudal peduncle, gill slit and the bases of the fins. The carapace has three ridges on each side of the body. The lower ridges have a pair of recurved spines in its centre and the upper ridge has smaller recurved spines, also in its centre. The preserved specimens are brown in colour with numerous darker spots on the upper carapace with pale fins. [4] This species has a maximum published standard length of 10.6 cm (4.2 in). [2]
Kentrocapros spilonotus has been recorded from just two localities in the Hawaiian Islands, one near Laysan Island and the other on the Penguin Bank near Molokai and has been foudn at depths between 106 to 293 m (348 to 961 ft). [1]
Tetraodontiformes, also known as the Plectognathi, is an order of ray-finned fishes which includes the pufferfishes and related taxa. This order has been classified as a suborder of the order Perciformes, although recent studies have found that it, as the Tetraodontoidei, is a sister taxon to the anglerfish order Lophiiformes, called Lophiodei, and have placed both taxa within the Acanthuriformes. The Tetraodontiformes are represented by 10 extant families and at around 430 species overall. The majority of the species within this order are marine but a few may be found in freshwater. They are found throughout the world.
Ostraciidae or Ostraciontidae is a family of squared, bony fish belonging to the order Tetraodontiformes, closely related to the pufferfishes and filefishes. Fish in the family are known variously as boxfishes, cofferfishes, cowfishes and trunkfishes. It contains about 23 extant species in 6 extant genera.
Aracanidae, the deep sea boxfishes or temperate boxfishes, are a family of marine ray-finned fishes belonong to the order Tetraodontiformes, which also includes the pufferfishes, triggerfishes and ocean sunfishes. The fishes in this family are found in the Indo-West Pacific region, particularly in the waters around Australia.
Tetrosomus gibbosus, commonly called camel cowfish because of the hump on its dorsal keel, is one of 22 species in the boxfish family, Ostraciidae. It is a ray finned fish. Other common names include helmet cowfish, humpback turretfish and thornbacked boxfish. It is most closely related to T. reipublicae, the smallspine turretfish. T. gibbosus is a species of boxfish found in the wide Indo-West Pacific. It has been recorded since 1988 on rare occasions in the Levantine waters of the Mediterranean Sea, likely following entry via the Suez Canal. It is the first species from the family Ostraciidae to be found in the Mediterranean Sea.
