Rajella fyllae is a species of skate in the family Rajidae. [3] [4]
The scientific name fyllae refers to the ship HDMS Fylla, from where the holotype was collected by the Fylla scientific expeditions of 1884 and 1886 to Greenland. [5]
It is sometimes called the round ray or round skate, [6] but those names are also used for the family Urotrygonidae or the genera Heliotrygon and Irolita . [7] [8] The name Fylla's ray is also used, perhaps by writers who thought that "Fylla" was the name of a person. [9] [10]
The round ray lives in the North Atlantic Ocean and Arctic Ocean. It is a benthic fish, found in depths of 147–2,055 m (482–6,742 ft), typically 300–800 m (980–2,620 ft); in cold deeper continental shelf waters, 3–5.5 °C (37–42 °F). [11] [12]
Like all rays, the round ray has a flattened body with broad, wing-like pectoral fins. Its maximum length is 60 cm (2.0 ft). Its dorsal (upper) surface is grey or brown, with the lower surface light gray or fawn, with dark patches on the pelvic fins and axils of pectoral fins. [13]
Rajella fyllae feeds on mysids, copepods, crustaceans and amphipods. [14]
In breeding, there is a distinct pairing of the male and female, with an "embrace." It is oviparous, the eggs being oblong with stiff pointed "horns" in the corners; they are deposited in sandy or muddy flats. [15]
Skates are cartilaginous fish belonging to the family Rajidae in the superorder Batoidea of rays. More than 150 species have been described, in 17 genera. Softnose skates and pygmy skates were previously treated as subfamilies of Rajidae, but are now considered as distinct families. Alternatively, the name "skate" is used to refer to the entire order of Rajiformes.
Chimaeras are cartilaginous fish in the order Chimaeriformes, known informally as ghost sharks, rat fish, spookfish, or rabbit fish; the last three names are not to be confused with rattails, Opisthoproctidae, or Siganidae, respectively.
Narcinidae, or numbfishes, are a family of electric rays. They are bottom-dwelling cartilaginous fishes with large, rounded pectoral fin discs and long tails. They can produce an electric discharge for defense, from which their scientific name is derived.
Carcharias is a genus of mackerel sharks belonging to the family Odontaspididae. Once bearing many prehistoric species, all have gone extinct with the exception of the critically endangered sand tiger shark.
Rajella is a genus of skate found deeper than 150 m (490 ft) in the Pacific, Atlantic and Indian oceans.
The broad skate is a poorly known species of skate in the family Rajidae. It occurs at depths of 846 to 2,324 metres, and has been observed via remotely operated underwater vehicle by the Monterey Bay Aquarium Research Institute as deep as 3,167 metres (10,390 ft), making it one of the deepest-occurring skates known. It is sporadically distributed in the Pacific Ocean, from the Gulf of Panama to British Columbia and the Bering Sea, to the Tohoku Slope off northern Honshu and the Okhotsk Slope off Hokkaido. The species name, badia, comes from the Latin batius meaning "brown", referring to its color.
Marsha's lanternshark is a species of shark in the family Etmopteridae. It is found in the Western Pacific near the Philippines and can reach 23.4 cm in length.
The spotted ray or spotted skate is a species of skate in the family Rajidae.
The Jeffrey's goby is a species of goby fish.
Scopelogadus beanii, or Bean's bigscale, is a species of ridgehead fish. It is named for Tarleton Hoffman Bean.
The black seasnail is a species of fish in the family Liparidae (snailfish).
Cataetyx alleni, sometimes called Allen's brotula, is a species of fish in the family Bythitidae.
Nansenia oblita, also called the forgotten argentine or the Mediterranean large-eyed argentine, is a species of fish in the pencil smelt family (Microstomatidae).
The Arctic rockling, also called the silver rockling or Arctic threebeard, is a species of fish in the family Lotidae.
Sudis hyalina is a species of fish in the family Paralepididae (barracudinas).
Lycodes terraenovae, also called the Newfoundland eelpout, Atlantic eelpout or fish doctor, is a species of marine ray-finned fish belonging to the family Zoarcidae, the eelpouts. It is found in deep waters of the Atlantic Ocean.
Bigelow's ray, also called the chocolate skate or Bigelow's skate, is a species of skate in the family Rajidae. It is named in honour of the oceanographer Henry Bryant Bigelow.
The deepwater ray, also called the deepwater skate or abyssal skate, is a species of skate in the family Rajidae.
