Fenestraja plutonia is a species of cartilaginous fish in the family Gurgesiellidae. It is commonly known as the underworld windowskate or Pluto pygmy skate. [2] The underworld windowskate is known from patches of continental slope in the western Atlantic Ocean between the coasts of the southern United States and Suriname. [1]

Etymology

The underworld windowskate's genus name, Fenestraja, comes from a combination of two words. Fenestre is a Latin word meaning window, which in this case refers to a small opening in bone. [3] A second Latin word, Raja simply refers to the genus as a skate/ray of the family Rajidae. Its species name is a reference to Pluto (Ancient Greek : Πλούτων, Ploutōn) the Greek god of the underworld. [4]

Taxonomy

Samuel Garman

The underworld windowskate was initially described by Samuel Garman in 1881 as Raja plutoni. Garman also considered placing the species in other genera such as Breviraja and Gurgesiella . [5] The first specimens had been caught during dredging of the Atlantic coast during the summer of the previous year. [5] In 1947, another skate from the Gulf Stream was described by Henry Fowler as Raja acanthiderma. [6] However this species designation has been suggested to be a synonym for the underworld windowskate, once the species was officially moved from Raja to Fenestraja. [7]

Description

The underworld windowskate has a heart-shaped disc, with denticles on the blunt snout, around the eyes, on the pectoral fins and down the sides of the long tail. [8] It is generally yellowish, grayish, or purplish brown on top, with dark spots. The ventral surface is yellow-white, and the tail has several dark bands. [8]

Distribution and habitat

According to the IUCN, five populations of the underworld windowskate are known, all from the western Atlantic Ocean. [1] The northernmost ranges on the North American continental shelf from North Carolina to Key West, including the Straights of Florida. [1] Another population is known from the waters around Andros Island in the Bahamas and in the Tongue of the Ocean. [1] A third area of continental shelf, this time in the Gulf of Mexico from the Chattahoochee River delta to the Mississippi River Delta is also known to contain the species. [1] Finally, two widely separated groups occupy the southern Caribbean Sea, the first off Costa Rica, near Puerto Limon, and the second from the South American continental shelf near Caracas, Venezuela, to Paramaribo, Suriname. [1]

Outside of these general ranges, specimens have been collected from the waters off Colombia, Ellesmere Island, in the eastern Gulf of Mexico, and James Bay, Canada. [9] Individuals have also been spotted by divers in southern Mexico, and in 1891 a specimen supposedly belonging to F. plutonia was collected from the California coast, even though the underworld windowskate is overwhelmingly an Atlantic species.

The frilled shark, also known as the lizard shark, is one of the two extant species of shark in the family Chlamydoselachidae. The frilled shark is considered a living fossil, because of its primitive, anguilliform (eel-like) physical traits, such as a dark-brown color, amphistyly, and a 2.0 m (6.6 ft)–long body, which has dorsal, pelvic, and anal fins located towards the tail. The common name, frilled shark, derives from the fringed appearance of the six pairs of gill slits at the shark's throat.

<i>Raja</i> (fish) Genus of cartilaginous fishes

Raja, also known as raia, is a genus of skates in the family Rajidae containing 16 species. Formerly a wastebasket genus, many species historically categorized here have been moved to other genera in the family, such as Amblyraja, Beringraja, Dipturus, Leucoraja and Rostroraja. Raja are flat-bodied, cartilaginous fish with a rhombic shapes due to their large pectoral fins extending from or near from the snouts to the bases of their tails. Their sharp snouts are produced by a cranial projection of rostral cartilage. The mouth and gills are located on the underside of the body. They may be either solid-coloured or patterned, and most skates have spiny or thorn-like structures on the upper surface, while some species contain weak electrical organs within their tails. Mating typically occurs in the spring and the female lays numerous eggs per clutch which are encapsulated in leathery cases, commonly known as "mermaid’s purses". Species vary in size, ranging from about 40 to 140 cm (1.3–4.6 ft) in length. These bottom-dwellers are active during both day and night, and typically feed on molluscs, crustaceans and fish. Raja skates are found in the East Atlantic, also in the Mediterranean, and western Indian Ocean, ranging from relatively shallow water to a depth of 800 m (2,600 ft). Skates and related species have fossil records dating from the Upper Cretaceous period, thus this well-adapted species is quite ancient.

<span class="mw-page-title-main">Barndoor skate</span> Species of cartilaginous fish

The barndoor skate is a species of marine cartilaginous fish in the skate family Rajidae of the order Rajiformes. It is native to the northwestern Atlantic Ocean, and is found from the Grand Banks of Newfoundland and the southern side of the Gulf of St. Lawrence south to North Carolina. The fish is one of the largest skates found in the North Atlantic Ocean, reaching lengths up to 1.5 m (5 ft). It is carnivorous, feeding on invertebrates and other fish found near the sea floor.

<span class="mw-page-title-main">Spotback skate</span> Species of fish

The spotback skate is a species of fish in the family Arhynchobatidae. It is found off the Atlantic coasts of Argentina, Brazil, and Uruguay where its natural habitat is over the continental shelf in the open sea. It is a large fish, growing to over a metre in length. It feeds mainly on other fish according to availability, with shrimps, octopuses and other invertebrates also being eaten. Reproduction takes place throughout most of the year, with the eggs being laid in capsules that adhere to the seabed. The spotback skate is the subject of a fishery and is thought to be overfished, resulting in Greenpeace adding the fish to its red list of fish to be avoided, and the International Union for Conservation of Nature listing it as an "endangered species".

They are unusual among skates in that their egg cases may contain up to seven eggs each. This species is one of the most commercially important skates off California and is sold for food.
